Abstract
A mathematical model of the polydisperse medium mixing process reflects its stochastic features in the form of uneven distribution of phase elements on the time of their presence in apparatus, particle size, ripple retention of the apparatus, random distribution of the material and thermal phase flows of the working volume, heterogeneity of the medium physical- and chemical properties, complicated by chemical reaction. For the mathematical description of the mixing process of animal feed ingredients in the presence of chemical reaction the system of differential equations of Academician V.V. Kafarov was used. Proposed by him hypothesis based on the theory of Markov’s processes stating that "any multicomponent mixture can be considered as the result of an iterative process of mixing the two components to achieve the desired uniformity of all the ingredients in the mixture" allows us to consider a process of mixing binary composition in a paddle mixer in the form of differential equations of two ingredients concentration numerous changes until it becomes a homogenous mixture. It was found out that the mixing process of the two-component mixture is determined in a paddle mixer with a constant mixing speed and a limit (equilibrium) dispersion of the ingredients in the mixture i.e. with its uniformity. Adjustment of the model parameters was carried out according to the results of experimental studies on mixing the crushed wheat with metallomagnetic impurity, which was a key (indicator) component. According to the best values of the constant of the continuous mixing speed and the equilibrium disperse values of the ingredients contents, the mathematical model parameters identification was carried out. The results obtained are used to develop a new generation mixer design.

Abstract
Researches of thermal and rheological properties of cream- and vegetable spread are necessary for the scientific substantiation of their obtaining process, namely mixing and crystallization processes. As the object of research, we chose a cream- and vegetable spread, with the following composition: peanut butter 10%; wheat germ oil 10%; linseed oil 20%; butter 59.8%; emulsifier 0.2%. With the data obtained in the course of research of the rheological properties of cream- and vegetable spread, one can subsequently generate recommendations for optimization of technological modes of production. In particular, one can solve problems of intensification of hydro-mechanical and thermal processes by carrying them out at such a temperature and speed when the maximum preservation of the produced product structure will be achieved. Determination of thermal characteristics was carried out in the apparatus for the study of thermal and rheological properties of viscoelastic liquids Coesfeld RT-1394H. Rheological researches of cream- and vegetable spread were carried out on a series of viscometers SV-10 and PB-8m. The graphs of spread dynamic viscosity dependence on the temperature, and the dependence of the effective viscosity of the spread and vegetable oils on the shear rate were built according to experimental data. The data obtained is rational to choose the equipment for processing and production of cream- and vegetable spread, to simulate processes taking place in the production process, to solve problems of intensification of thermal and hydro-mechanical processes reasonably, by conducting the production process at temperatures that do not cause the destruction of the product structure.

Abstract
Research and innovation activity to create energy-efficient processes in the melon processing, is a significant task. Separation skin from the melon flesh with their subsequent destination application in the creation of new food products is one of the time-consuming operations in this technology. Lack of scientific and experimental base of this operation holding back the development of high-performance machines for its implementation. In this connection, the technique of the experiment on the separation of the skins of melons in the pilot plant and the search for optimal regimes of its work methods by statistical modeling is offered. The late-ripening species of melon: Kalaysan, Thorlami, Gulab-sary are objects of study. Interaction of factors influencing on separating the melon skins process is carried out. A central composite rotatable design and fractional factorial experiment was used. Using the method of experimental design with treatment planning template in Design Expert v.10 software yielded a regression equations that adequately describe the actual process. Rational intervals input factors values are established: the ratio of the rotational speed of the drum to the abrasive supply roll rotational frequency; the gap between the supply drum and the shearing knife; shearing blade sharpening angle; the number of feed drum spikes; abrading drum orifices diameter. The mean square error does not exceed 12.4%. Regression equations graphic interpretation is presented by scatter plots and engineering nomograms that can be predictive of a choice of rational values of the input factors for three optimization criteria: minimal specific energy consumption in the process of cutting values, maximal specific performance by the pulp and pulp extraction ratio values. Obtained data can be used for the operational management of the process technological parameters, taking into account the geometrical dimensions of the melon and its inhomogeneous structure.

Abstract
The article describes solutions to the problems of declining productivity of ceramic membrane elements for wine processing on the final manufacturing phase. A relative stabilization of filtration velocity, venting efficiency and wine lightening were experimentally confirmed during contacts with oscillation waves of ultrasonic transmitter on the ceramic filter. Which significantly reduced the cost of various preservatives to increase periods storage. To study the processes of wine processing by the proposed method it was made an experimental installation on the basis of pilot machine MRp-1/2 for bottling of quiet liquids and an ultrasonic device "Volna– M" UZTA-1/22-OM with a firmly, waveguide which transmits sound, fixed filter frame on the ultrasound emitter. To stabilize the performance of ultrasonic units with ceramic membrane elements without quality deterioration of wines it was empirically determined rational parameters of power of ultrasound input and pressure in the system. The given derived dependencies and graphs allow to define the time of relatively stable operating filter regime. It was revealed a significant cost reduction on filtration, as it allows escape from the contamination of the product by various preservatives, and increasing of storage duration in a sealed container during aseptic filling without a thermal sterilization. Ultrasonic emitter contact by superposition wave vibrations on the ceramic filter increases not only the efficiency of gas removal, but also improves the organoleptic characteristics, stabilizes the filters, improves their productivity. Gas removal creates unfavorable conditions for development of the yeast, which in turn increases the shelf life of semisweet wine.

Abstract
The evaluation of application of steam recompression for epuration column heating was carried out in the work. Researches on epuration process were carried out on an industrial brew rectification apparatus of Veselolopansky distillery. During the experiment, column apparatus operating parameters interrelations with the heat pump energy characteristics were analyzed, variants for epuration column operation with a heat pump with different vapor pressure entering the compressor by varying the compression pressure were examined. The experiments carried out allowed to determine the optimum vapor pressure of compression, providing the column operation without the heating steam supply. At a slight overpressure of vapor the optimal compression ratio is 3.4–3.7 kPa, the pressure after the compressor is 352–376 kPa; in the bottom part of column at the atmospheric pressure the optimal compression pressure is 303–325 kPa, the compression ratio is 4.0–4.4. For the low-pressure-regime use the optimum pressure is 252–275 kPa, the degree of compression-stump is 4.9–5.5. Thermodynamic analysis modes of epuration showed that epuration column working with a heat pump has the highest exergy efficiency (32.6%). Use of heat pump saves 1.03–1.15 kg of steam at the rate of 1 liter of ethanol, introduced in the column with supply. Heat pumps can be used to reduce the energy intensity of BRA in obtaining high-quality rectified alcohol.

Abstract
The article is devoted to the development of a correction control algorithm by temperature mode of a periodic rubber mixing process for JSC "Voronezh tire plant". The algorithm is designed to perform in the main controller a section of rubber mixing Siemens S7 CPU319F-3 PN/DP, which forms tasks for the local temperature controllers HESCH HE086 and Jumo dTRON304, operating by tempering stations. To compile the algorithm was performed a systematic analysis of rubber mixing process as an object of control and was developed a mathematical model of the process based on the heat balance equations describing the processes of heat transfer through the walls of technological devices, the change of coolant temperature and the temperature of the rubber compound mixing until discharge from the mixer chamber. Due to the complexity and nonlinearity of the control object – Rubber mixers and the availability of methods and a wide experience of this device control in an industrial environment, a correction algorithm is implemented on the basis of an artificial single-layer neural network and it provides the correction of tasks for local controllers on the cooling water temperature and air temperature in the workshop, which may vary considerably depending on the time of the year, and during prolonged operation of the equipment or its downtime. Tempering stations control is carried out by changing the flow of cold water from the cooler and on/off control of the heating elements. The analysis of the model experiments results and practical research at the main controller programming in the STEP 7 environment at the enterprise showed a decrease in the mixing time for different types of rubbers by reducing of heat transfer process control error.

Abstract
Currently, wireless technology is becoming the preferred, and in some cases the only possible for the information communication devices. If you need coverage of a large space with a complex configuration arises the need to efficiently host multiple Wi-Fi emitters, providing a stable connection with each possible location of the receiver signals. Suppose we have a model that allows to determine the coverage of a stable connection Wi-Fi emitter at a given spatial point. Then the problem of locating Wi-Fi emitters can be formulated as determining a discrete set of locations of transducers satisfying the condition. Otherwise, it is necessary to determine the positions of all the emitters that completely cover a given area, and the number of emitters should be minimal. In this formulation it is the task of the lowest coverage – the problem of finding the smallest set of columns of the matrix, "covering" all of her lines. To develop methods for solving a problem of the smallest covering usually resort to its matrix interpretation, which reduces to the problem of the smallest dominating set of a graph. From the point of view of the formulation of the problem of the smallest covering two cases are possible configuration of the coverage area of the surrounding space Wi-Fi emitters: 1. without variable. Its peculiarity is that the coverage area is completely defined by the location of the emitter. It is possible in the case where the coverage area of the symmetric or the orientation of the directivity diagram of the radiation is fixed. In this case it is possible to build a graph associated with the set of locations of emitters in which each point of placement are associated with adjacent vertices. In this formulation we arrive at the problem of the smallest dominating set of a graph. 2. Variable. It takes place in the case when the diagram of radiation is directed, and the coverage area may vary depending on the orientation of the emitter. That is, the actual emitter can be deployed in an infinite number of different provisions, but the limb covered points significantly limits the number of different orientations. In this case, each point position of the transmitter can be put into correspondence with several matrix rows and cover each point will correspond to exactly one column.

Abstract
Analytical study of the processes of heat conduction is one of the main topics of modern engineering research in engineering, energy, nuclear industry, process chemical, construction, textile, food, geological and other industries. Suffice to say that almost all processes in one degree or another are related to change in the temperature condition and the transfer of warmth. It should also be noted that engineering studies of the kinetics of a range of physical and chemical processes are similar to the problems of stationary and nonstationary heat transfer. These include the processes of diffusions, sedimentation, viscous flow, slowing down the neutrons, flow of fluids through a porous medium, electric fluctuations, adsorption, drying, burning, etc. There are various methods for solving the classical boundary value problems of nonstationary heat conduction and problems of the generalized type: the method of separation of variables (Fourier method) method; the continuation method; the works solutions; the Duhamel's method; the integral transformations method; the operating method; the method of green's functions (stationary and non-stationary thermal conductivity); the reflection method (method source). In this paper, based on the consistent application of the Laplace transform on the dimensionless time θ and finite sine integral transformation in the spatial coordinates X and Y solves the problem of unsteady temperature distribution on the mechanism of heat conduction in a parallelepiped with boundary conditions of first kind. As a result we have the analytical solution of the temperature distribution in the parallelepiped to a conductive mode free convection, when one of the side faces of the parallelepiped is maintained at a constant temperature, and the others with the another same constant temperature.

The simulation was performed at different parameters of the control object, which is characterized by a stable and an unstable state of the system. VA-den analysis of the numerical values of the roots and character of their location on the complex plane, which to you-water that the system is stable or unstable. To confirm the obtained results were calculated and presented dynamic characteristics of the closed-loop system under different conditions, which confirm the initial assessment, the root criterion. To determine the factor stability of multivariable digital systems is proposed to use the deviation of the maximum root of the characteristic equation from the stability boundary. The obtained results apply to the class of symmetric multivariable control objects. The approach to assessing the sustainability of multivariable system regulation can be effectively used in automatic mode during the synthesis of robust control systems multidimensional technological objects.

Abstract
Mathematical model of kinetics of charge deep levels in the forbidden band of the semiconductor, which takes into account the processes of carriers charge exchange between deep levels and both allowed bands, which adequately describes the nature of the non-exponential relaxation capacity, is proposed. A method for determining the spectrum of deep level transient spectroscopy having greater accuracy and resolution in comparison with traditional methods using a relaxation time approximation. The results of numerical experiments using the kinetics charge deep levels model in the frameworks of proposed approximations are presented. Account of generational and recombination components of charge exchange processes of all deep levels in the forbidden band of the semiconductor leads to the conclusion that the kinetics of ionization of these centers, in general, does not obey the Boltzmann statistics. Account of charge exchange processes between the deep levels a significantly effects on their recharge kinetics. Numerical analysis results show that the processes of deep levels ionization are more complicated than the staged-type kinetics. It is shown that in most cases stagedtype kinetics at deep level transient spectroscopy leads to significant methodological error in the parameters determination. From the results of numerical analysis follows, that the density of surface electronic states has a significant impact on the overall recharged kinetics of deep levels. Donor deep levels recharge analysis revealed not only the features of the deep levels ionization in semiconductors, but also allowed to answer some questions that are typical to all deep-level transient spectroscopy in general.

Abstract
Calculation of kinematic mechanisms is very time-consuming work. Due to the content of a large number of similar operations can be automated using computers. Forthis purpose, it is necessary to implement a software implementation ofthe mathematical model of calculation of kinematic mechanisms of the second class. In the article on Turbo Pascal presents the text module to library procedures all kinematic studies of planar lever mechanisms of the second class.

It is assumed that the known length of all links, the positions of all additional points of links and the coordinates of all kinematic pairs rack mechanism, i.e. this stage of work to determine the kinematics of the mechanism must be preceded by a stage of synthesis of mechanism (determining missing dimensions of links). Denote the coordinates of point C and considering that the analogues of velocities and accelerations of this point is 0 (stationary point), appeal to the procedure that computes the kinematics group the Assyrians (GA) third. Specify kinematic parameters of point D, taking the beginning of the guide slide E at point C, the angle, the analogue of the angular velocity and the analogue of the angular acceleration of the guide is zero, knowing the length of the connecting rod DE and the length of link 5, refer to the procedure for the GA of the second kind. The use of library routines module of the kinematic calculation, makes it relatively simple to organize a simulation of the mechanism motion, to calculate the projection analogues of velocities and accelerations of all links of the mechanism, to build plans of the velocities and accelerations at each position of the mechanism.

Abstract
The paper considers that the most effective measure to reduce the number of road accidents when overtaking in areas with limited visibility is timely information about drivers driving conditions and the lack of an oncoming car within the danger zone. More reliable results give light boards included automatically when the car passes the corresponding sensor. In this light boards issued information must be obtained by the driver at such a distance from the places of concentration of traffic accidents in which the driver received it, would be able to freely make a particular maneuver. To determine this distance, we used the method of calculating the path of overtaking. Analysis of the various options the traffic situation, taking place on the road with an unsecured appearance, shows that the most disadvantaged will be the following: one of the first bands moving slow-moving car, followed by a time interval of 3 - speedboat driver who wishes to overtake; in the opposite lane at the expiration of 3 from the moment of the passage of low-speed vehicle-speed sensor moves. A scheme for the organization and regulation of traffic on road sections with unsecured visibility with in the power of information devices. Information that warn drivers about traffic conditions on the road with limited visibility, set on the way to a dangerous site from both directions at a distance of visibility is not less than 400 m, and traffic does not exceed 400 authors / h per lane. The economic effect of the introduction of information devices is achieved by reducing the number of traffic accidents on the road with limited visibility in plan and profile, as well as by increasing the Flow rate of road traffic.

Abstract
Because of the difficulty of constructing rigorous mathematical models of technological, biomedical and economic facilities have been developed methods of forecasting based on statistical analysis. The complexity of the analyzed object is equivalent to its information capacity. The maximum capacity is achieved if all of the object’s state is equally likely. The relative uncertainty of information obtained crucial system complicates decision-making on the state of the object. To reliably predict the state of the object is measured several characteristics, the measurement range is broken into grades, but within each gradation is made by averaging of the signal. Next solve two problems: the detection problem (detection of deviation of operation from normal mode) and a recognition task (assessment of the degree of deviation from the norm). The number of gradations of the trait is closely linked to the capacity of the training sample (at least 40). In the description of the system from 8 to 30 signs and power training samples from 40 to 120, the method includes the formalization of the signs in the first stage, the selection using a correlation analysis of the most informative features in the second stage and a classification of the state of the object by the method of cluster analysis allowed to correctly diagnose the system status in emergency mode with an accuracy of between 89 to 98%. The proposed information approach allows the classification and prediction of technical, economic and biomedical systems of any complexity, which opens up the possibility of predicting the behavior of such systems and control the appearance of interference.

Abstract
The macroscopic polarization is the most essential concept in any phenomenological description of dielectric media. The presence of a spontaneous macroscopic polarization is the defining property of a ferroelectric material that is central to whole physics of ferroelectrics. Based solely on symmetry considerations, Landau theory can provide a reliable description of a system equilibrium behavior near a phase transition. This phenomenological approach allows giving relations between measurable quantities using a minimal set of input parameters that can be determined by comparison with physical experiment or numerical first-principles calculation. Now, the problem of true presentation of Landau-Devonshire potential for different materials is outstanding. The properties of Landau-Devonshire thermodynamic potential (TP) for ferroelectric materials in this article is investigated on the example of barium titanate. The previously approved topological method of research of nonlinear properties of ferroelectrics is applied. The cellular complexes approach use for interpretation of TP extremes. The new representation of the 8-order polynomial TP compared with previously used 6-order representation. For the 8 order potential the structure of metastable states for barium titanate is presented in the vicinity of first-order phase transition point at T = 5°C. New method proposed for the qualitative description of the metastable states structure that TP generates. Based on the method the temperature regions are pointed where the 6 and 8 order potentials predicting for the metastable states are qualitatively different.

Abstract
Fruiting bodies of mushrooms are rich in proteins. The most rich in proteins is Boletus edulis (white mushroom), and total protein contains all the essential amino acids. The low bioavailability of proteins Boletus edulis stimulates the search for ways to improve. One way to improve the bioavailability of nutrients of Boletus edulis is an extraction. This article presents the results of studies of extracts of white mushroom (Boletus edulis), obtained using different methods of processing the chopped dry fruiting body. The effect of physical and biotechnological parameters on the efficiency of the extraction of proteins was studied. The spectral characteristics and protein content of the obtained extracts were determined. It is shown that the ultrasonic extraction activation leads to the most efficient protein extraction(an increase of 9.5%). It is also significantly affected by the duration of extraction. The use of the enzyme preparation in the investigated ratios do not have a positive impact, however, enzymatic treatment in conjunction with ultrasound treatment increased the efficiency of 13.5%, showing the complex diffusion processes in the fruiting bodies of mushrooms. Increasing the length of the extraction, despite the high content of protein in the extract, is impractical because of the risk of bacterial contamination of high-nutritive extract. Increasing the temperature of the process has no significant effect on the protein content, but it reduces the value of the extract, due to the destruction of heat-labile components, which include vitamins and secondary metabolites. The extract application rate for curd product was determined. For the test samples organoleptic characteristics and titratable acidity were determined. The most appropriate dose of the extract in the manufacture of making curd product is 15% by weight of the finished product.

Abstract
Healthy nutrition is one of the main factors that becomes stronger the human immune system, especially in the big cities, forms intellectual abilities of people, increases the qualitative characteristics of living standards etc. The most important components of a healthy nutrition are vegetables and products from them. Rather high moisture content of many vegetables, e.g., fruit, partially fills the needs of the human organism in water, lowers the energy value of the diet, enhances the motility of the gastrointestinal tract. In this regard, the improvement of technology universal product from regional vegetables available has got importance, prolonged pronounced social effect and contributes to health improvement. Among vegetables the zucchini include diet properties, but the use of them is accompanied by certain difficulties associated with seasonal logistics and the limited range of products from them. In this work, there were studied the varietal characteristics of the zucchini, zoned in the North-West region, in terms of their technological properties, morphological characteristics and biochemical composition of fruit during ripening. Were investigated the optimal ways of canning zucchini by drying with freeze-drying and infrared heating that allows you to provide catering universal semi-finished product during the whole year, not only in areas of cultivation, but also in areas outside of growing vegetables. There was discovered the effect of anomalous dehydration of fruit vegetables in the result of the study , which helped to explain the increased, in comparison with other types of vegetables, losses during heat treatment and to justify their methods and technological parameters of drying. It was found that one of the reasons for the reduction of mechanical strength parenchymal tissue of fruit vegetables, is the destruction of cell walls by increasing the pressure inside the air inclusions, in contrast to some other types of fruit vegetables, the softening of which are caused by changes in protopectin cellulose and middle lamellae of cells. The result of this study helped to develop the recipes and technology of a universal semifinished product from zucchini for enterprise of catering.

Abstract
In diseases of the gastrointestinal tract, it is recommended to refrain from food oxidation. Therefore, the inclusion in the diet of bakery products with low acidity is important in the diet for such patients. One way to reduce the acidity of bread is the use of electric aqueous solution (EAS). Studied the effect of EAS with different values of рН (7.42; 9.34; 11.12) on the properties of dough and quality of bread from wheat flour first grade. The dough is kneaded straight dough method. In the fermentation process investigated the change in effective viscosity and titratable acidity. After fermentation the dough is molded, the test workpiece is subjected to proofing and baking. In ready from deliah determined the acidity, moisture content, porosity and specific volume. It is established that all samples of the test there was a decrease of effective viscosity in the fermentation process due to the occurrence of physico-chemical processes. The maximum value of effective viscosity is characterized by the semi-finished product, obtained using EAS рН of which 11.12 (3474 PA⋅s). It is revealed that the least value of ultimate рН (1.7 deg) also had a sample on EAS with a рН = 11.12. The use of catholyte fraction of HRES with the given value of рН allowed to decrease the acidity in the finished product (45.5%) compared with the control in the pilot study value was 1.2 degrees, while in the control to 2.2. The research concluded that the use of electroactivated aqueous solution suitable for the production of bakery products of low acidity.

Black currant was chosen the main raw material for the development of the beverage production technology. It is characterized by a high content of bioactive components that increase the adaptive abilities of human body. The purpose is to use ultrasonic extraction method in the preparation of functionally directed actions beverages. Extractor with submerged ultrasonic emitter was used as an experimental device. The essence of its operation is as follows: a mixture of the extractant and the plant substrate in different ratios was loaded into a container with the emitter, then the ultrasonic generator was turned on. The vibrations of ultrasonic frequency (22 kHz) made high-frequency mechanical vibrations that caused the formation of intense cavitation areas and diffuse dissolution of cell substrates in the extractant in the treated mixture. The ultrasonic extraction technique involves brief contact of berries and extractant (up to 15 minutes) upon application of ultrasonic vibrations. With an increase in exposure time, the yield of biologically active substances increases to reach an equilibrium state corresponding to the most complete exhaustion of raw materials. All this leads to a significant acceleration of the transition from the active ingredients from the raw materials into the extractant to obtain a product with improved physical - and chemical, organoleptic characteristics, as well as a higher antioxidant activity.

Abstract
Currently pectin is widely used in food industry, pharmaceutical industry, medicine, and other industries due to its ability to form gels of different strength, and to having curative and preventive characteristics. Kabardino-Balkaria is one of the regions with industrial amounts of fruits, rich in pectin substances. In order to select the most promising raw materials for commercial production of pectin in the fruit of zoning in the territory of the Republic was determined the content of pectin substances and their physico-chemical parameters in the varieties of apples (Idared, Granny Smith, Florina), pears (Clapp Favorite, Talgar beauty), apricots (Ruddy, Salah), plums (Stanley, Kabardian early). It was established that the greatest number of pectin substances among varieties of apples is allocated in apples in Granny Smith sort, in pears in Clapp Favorite, in plums in Stanley, and in apricots in Salah sort: 1,14, 0,98, 1,03, 0.71% in the raw substance, respectively. It was found that pectin from apples, plums, apricots and pears with the exception of Clapp Favorite is highly etherified. The degree of methoxylation of pectin from apples varies between 70.71–81.85%, plums – from 60.99 to 67.31%, apricots – from 63.72 to 68.25%, from the pear Talgar beauty – 56.0%. Pectin from apples Granny Smith has the highest value of the degree of etherification. A high degree of etherification of pectin in this sort of apples can be recommended as thickening agents in different branches of food industry. Pectin from pears Clapp Favorite has low degree of etherification – 40.7%, that shows the evidence of their possible use in the manufacture of therapeutic and prophylactic purposes. According to the planned program of intensive horticulture in the region, by 2020 the area of Apple orchards will be up to 15 thousand hectares, and the harvest – up to a million tons. Taking that fact and the obtained experimental data into account, we assume that apples are industrially important raw material for the production of pectin.

Abstract
The study of mixed-ligand complex formation is important problem of coordination chemistry currently. The ligands of different nature within the domestic environment of the complex, have a mutual influence, changing the chemical properties of complexes (acid-base, oxidation-reduction, the rate of ligand substitution in the internal environment) and their biological activity. According to the literature, the issues of mutual influence of ligands, which leads to a change in the reactivity of the complexes have been widely studied with the assistance of ligands of different nature. In recent years sharply increased interest in nanoobjects of different nature. This is due to the fact that many of the physical, chemical and biological properties of the nanoparticles significantly different characteristics from those of larger (macroscopic) objects. The aim of the study was to examine the conditions of formation (ratio of components, acidity) in solutions of mixed-metal biocomplexes copper. The studies have shown that the conditions of synthesis have significant impact on obtaining nanoparticles of zinc, copper and cobalt. The study of morphology and size of the resulting nanoparticles were performed on a scanning electron microscope Quanta FEG 650 in high vacuum (pressure in the chamber 8⋅10-3 to 3⋅10-3 Pa) mode. The resulting nanoparticles are studied metal particles kanglomeraty complex structure of various shapes and sizes up to 200 nm, and the crystals are spherical shape sizes of 40–90 nm.

Abstract
Analyzed the system of drying plant air cleaning, specializing in the production of food powders, dust emission identified place in the shop drying in the production of soluble dietary powders, the parameters of the dryer exhaust coolant, analyzed the properties of the product, as well as determined the effectiveness of the use of air purification equipment. Analyzed used at the enterprise two-stage cleaning system. As a first purification stage conical cyclone installed as a second stage purification analyzed dust collector is proposed with internal circulation of the liquid. It was found that the drying of the powder contained in the emissions of a large proportion of the fine fraction of dust. Several studies have been conducted with this food dust. It was found that the collection efficiency in the cyclone ranged from 68% (tea dust) to 92% (dust kvass wort). Analyzing the data obtained indicated that the efficiency of cleaning exhaust coolant is heavily dependent on the food composition of disperse dust, and less than 10 microns particles is insufficient. It is proposed to use for cleaning the coolant wet dust collector with internal circulation of the liquid. The regularities of change of concentration of solids in the cleaning liquid, its viscosity and surface tension with increasing operating time since the start of the dust collector. It is found that increasing the concentration of solids in the cleaning liquid increases with the operating time of the machine since the start-up leads to changes in surface tension and viscosity of the liquid. It is shown that the effective dust collection in the machine decreases as the viscosity of the working fluid. Both theoretically and experimentally established patterns may be used when calculating the optimum specific liquid flow to provide effective cleaning and releases the trapped product return process cycle.

Abstract
The possibility of use of dispergators of various nature for production of rubber technical products with expanded temperature conditions of operation is studied. It is investigated influences of dispergators of Dispergator FL and INT 159 on properties of rubber mixes for receiving products with high resistance to thermal aging or frost resistance. Research of influence of modifiers was conducted for rubber mixes on the basis of butadienenitrile rubbers synthetic (BNRS)-18 and BNRS-28. I’s established that at addition of a dispergator of Dispergator FL the indicator of relative deformatstion of compression (RDC) and respectively heat stability of rubbers increases. Introduction to structure of elastomeric composition of a dispergator of INT 159 practically doesn’t influence frost resistance, and Dispergator FL worsens her (the coefficient of frost resistance decreases by 15.4–17.8%). Possibly it is connected with the fact that at the lowered temperatures in the presence of Dispergator FL there is a bigger delay of relaxation processes and decrease in energy of the thermal movement of links of macromolecules of rubbers. It becomes insufficient for overcoming of intermolecular interaction in the modified system and commission of conformational transitions of macromolecules under the influence of external loading. Mechanical energy is to a large extent mentioned not on change of a form of macromolecules, and on their mechanodestruction. However, it increases heat stability since it that is higher, than molecular mobility is lower. INT 159 dispergator components, settling down on borders of supramolecular formations of elastomers, increase mobility of links of macromolecules of rubbers, weaken chemical bonds in them, reduce thermal stability, but at the same time INT 159 dispergator practically doesn’t reduce frost resistance therefore it is expedient to apply it when receiving frost-resistant elastomeric composition. Thus, when receiving thermostable elastomeric compositions it is necessary to use Dispergator FL, and frost-resistant – INT 159 dispergator.

Abstract
The effect of new promoters on the adhesion of elastic and strength properties unfilled elastomeric compositions based on synthetic isoprene rubber SKI-3 and also on the structure of their vulcanizates are investigated. Synthesized adhesion promoters constitute silica fillers modified with cobalt, nickel, and a combination of cobalt and nickel. They contain on the surface a reduced number (compared with industrial stearate, cobalt) ions of metals of variable valence. Tests are carried out to determine the dependency of changes of the tensile strength, the elongation at break and the density of the crosslinking of rubbers on dosages of the investigated adhesion promoters and amounts of metal ions on their surface. The effect of type and dosage of the synthesized promoters of adhesion of rubber to steel brassedcord on heat aging resistance of elastomeric compositions are established. It is established that the vulcanizates containing synthesized adhesion promoters have greater high temperatures resistance as compared with the rubber materials containing industrial cobalt stearate. Increasing dosages of modified silica acid fillers in elastomeric compositions, quantity of metals on their surface leads to the decrease of the resistance of vulcanizates to heat ageing. While Nickel ions have less oxidation effect on rubber, compared to cobalt ions that may be due to their lesser activity It is determined that the introduction of adhesion promoters leads to the formation of additional cross-linking. It is revealed that use the mineral promoters in the elastomeric compositions affects less the density of cross-linkage of rubber after heat aging as compared with the cobalt stearate. When administered in an elastomeric composition the silica modified nickel, increasing the crosslinking density of rubber upon exposure to elevated temperatures was observed.

Abstract
When buying enterprises as a property complex, firm-the buyer can pay for it as excess cost of the acquired entity on its balance sheet, and an amount less than the value of the assets on the balance sheet of the acquiree. Based on the requirements of the Russian legislation, in the account of the buyer acquires an intangible asset that distinguishes the Russian from the international practice. International financial reporting standards do not recognize goodwill an intangible asset of the buyer enterprise. Therefore, it is necessary to specify the Russian practice of accounting transactions in the purchase of enterprises as property complex. The article presents a definition of the property complex, based on the requirements of the Civil Code of the Russian Federation, highlighted the stages of transfer of the property complex of the specified accounting documents that must be decorated, the analysis of the approaches of domestic and foreign authors to the recognition and measurement of goodwill, studied the specificity of the requirements of the Russian normative-legislative acts to the category “goodwill”, “intangible asset”. Based on the requirements of the Russian legislation, a positive goodwill is recognized in intangible asset (goodwill), in contrast to the negative goodwill (badwill), which immediately applies on other income of the organisation – the buyer of the enterprise – a property complex. On the positive business reputation, then the requirements of the Russian legislation, a positive goodwill is recognized intangible asset. In this paper, the authors proposed a model accounting for the purchase of enterprise as property complex as a result of which the acquisition price of an enterprise as a property complex exceeds its carrying amount of the assessment, therefore, in accounting, the buyer acquires an intangible asset in the form of a positive business reputation, compiled and substantiated recommended to reflect this fact of financial and economic activities of the correspondence of accounts.

The article analyzes the main trends and particular conditions existing innovation infrastructure in the regions of the Southern Federal District, promotes the commercialization of scientific and educational activities of the sector. It was found that the formation of an effective innovation infrastructure of the region depends on its specificity. In this regard, for the formulation of effective formulas for the construction of the innovation sector of regional economies need to analyze the existing institutions and identify the main points of growth of individual regions. However, in regions concentrated in one federal district it is possible to identify common trends. So the author of the study based on the analysis of these trends come to the conclusion that for all regions is the general low level of development of financial institutions that promote innovation, as well as the weak link between the scientific and educational sphere and the real economy. Summing up the results of the analysis of formation of regional infrastructure, we can conclude that it is currently in the Southern Federal District, Volgograd Region in particular observed the completion of the institutional and infrastructural conditions for the development of innovation. Meanwhile, the existing elements of the innovation infrastructure in the regions characterized by fragmentation and a lack of integration ties, ensuring the implementation of the life cycle of innovation. Particularly acute is the problem of the development of infrastructure of venture financing in science and technology, providing an effective mechanism for technology transfer. To the list of priorities should include the creation of a system of information support of innovation. In order to develop recommendations to strengthen the orientation of research capacity to the needs of the regional economy is necessary to analyze the efficiency of the sector generating knowledge in terms of the commercialization process.

Abstract
Special economic zone – the tool of regional policy of the state used in regions where increase of an economic and social level of development is required, and questions of application of tax benefits and preferences in the territory of a special economic zone acquire special relevance. The purpose of this article is research of the questions concerning the mode of the taxation of special economic zones. In Russia still there is no consensus about the sizes and the special economic zone types, the mechanism of their activity and approach to management. Development of uniform methodology is necessary for the Russian legislation for effective creation of activity of special economic zones taking into account features of a territorial arrangement. This methodology can be developed on the basis of positive experience of functioning of free economic zones of the different countries of the world. In the real work with the help of economic and statistical methods data on development and results of activity of a special economic zone in the territory of the Russian Federation and the China are collected and considered. As an example of successful functioning of the Russian special economic zone the special economic zone "Alabuga" is considered, as an example of functioning in the territory of the China special economic zone Shenzhen and joint industrial park of China and Singapore in the city of Suzhou are considered. The analysis of experience of the China has allowed to draw conclusions on efficiency of development of certain territories of the China through introduction of special economic zones. This fact substantially depends on efficiency of mechanisms of creation and development of economic educations, a possibility of self-government and financial independence in these territories, attraction of the foreign investment capital. There aren't enough these mechanisms in functioning of the Russian special economic zones where concept special economic zone still remains new and disputable. Use of experience of the China in management and creation of activity of special economic zone will help to reach more effective indicators of activity of the Russian special economic zone, to enter the world market with more competitive goods and, as a result, to strengthen national economy.

Abstract
The evolution of well-known philosophers and economists views on wealth is considered: Voltaire, Adam Smith, JeanJacques Rousseau, Karl Marx, John Stuart Mill, Milton Friedman, John Maynard Keynes, Joseph Schumpeter, Georg von Wallwitz and others. Economics was initially studying ways and means of achieving wealth. The essence of wealth has changed dramatically in people's minds after the first and the second industrial revolutions. The world today is on the verge of the third industrial revolution (according to Jeremy Rifkin), or, as it is called by many scientists, the new tenor of technology. In the history of any civilization comes the moment of a radical direction change for new prospects or endangered. Not all civilizations were able to transform in time. However, in the past, the effects of civilizations collapse were limited in time, space, and never addressed the species. Currently, the high probability of temperature and planet geochemistry changes as a result of climate change can lead to mass extinction of animals, plants, and people. Humanity has the ability to transit into a stable post-carbon era in the middle of the century and to prevent catastrophic climate change. Currently, sustainable development is the mechanism used to achieve the ultimate goal of any country, enterprise and human development, which is wealth. Under controlled sustainable development we understand the system unity of not only economic, social, environmental, but also resource, technological, institutional activities, as well as a permanent interaction between development and economic safety.

Abstract
In this article authors have analysed the questions connected with globalization of economic space and the arising problems of migration of able-bodied citizens. The need to assess the conformity of the received skills and to recognise migrants’ skills in an expanding labor markets and reducing low-skilled personnel was revealed. Authors examined the professional standards’ merits in force in the territory of Russia, and revealed their shortcomings. They have defined that questions of verification of migrants qualification depend on national peculiarities of the host country and system of preparation of professional shots. It was found out that in Europe learning results obtained by different methods are recognized after the introduction of the system of education competence approach. They studied models of different systems of training and retraining of specialists, employed in different countries, based on their personal characteristics and validation of prior learning outcomes. Authors have come to the conclusion that, taking into account the specifics of Russian companies and the differences in the education system in Russia is inappropriate to apply the existing models developed by the international community. They justify the need for the creation of information and computer support for the evaluation process of competence formation. It was expressed the view that the definition of basic competences in the construction of learning paths is need. The synthesis of elements of competence “Know” was performed as example of a description of the individual graph construction. The view was expressed, that in the learning course formation its payback must be taken into account, in this connection, the authors proposed the integrated discipline assessment criterion in a hierarchical structure. The integrated criterion unites three groups of indicators of a course: consumer value, its requirement and resource intensity.

Abstract
One of the most important components in today's market is a party decision-making under risk and uncertainty. The first step in making such decisions - to adequately process the information for estimating the future value of assets and the interests of investors probabilities of each particular scenario. The next step is to choose the alternative that has the greatest utility for the investor. Each of these steps is associated with numerous difficulties, the roots of which stem from the specificity of human psychology. The article notes that an integral part of professional risk management is to identify the nature of the object of management in the sphere of economy. Since the domestic theory of risk management is being formed-tion, the problem of a clear comprehensive definition of “risk” becomes now particularly relevant-ness. The article deals with along with economic forecasts of the risks and the human factor in decision-tions solutions. Along with economic forecasts, the report focuses on psychological problems and attempts to take into account the human factor in decision-making at the forecast of risks arising in the company. The important parameters are the status and position of the person in the society, as well as its social well-being. Analysis Meto-ing risk assessment concluded that the need to develop new models and methods of risk management, taking into account the four-lovecheskogo factor. Economic psychology and its applications have developed into a special branch of economic knowledge - the so-called behavioral economics, which surely develops a wide range of economic issues - from the actual theory of individual behavior to the problems of public choice and the financial economy. The most interesting item is the fact that the concept of “risk” is considered from different points of view - as the economist-mathematician with the position, and a psychologist.

It is emphasized that the course of structural economic changes, selected by the Russian government actualizes the issue of increasing the competitiveness of Russian industry on a global level that, in turn, contributes to the implementation of effective management models at the enterprises and organization of internal processes. Positively recommended concept of lean production abroad became popular in Russia in early 2000’s. First successful example of its implementation – CJSC “Ford Motor Company” is considered. A large number of enterprises which represent state corporations “Rosteh” and “Rosatom”, industrial group “Basic element”, OJSC “Russian Railways” and which are individual major representatives of the Russian industrial sector are investigated. Different ways of development of lean production by Russian enterprises are analyzed and the most common way – independent interpretation and implementation is identified. Review of the tools of this management model used at the Russian enterprises is paid great attention. The prevalence of such tool as 5S (approximately 87,5%), because of its visible simplicity of understanding and ease of implementation is noted. The most important indicator – the economic effect of the introduction of the lean production concept at the enterprises of Russian industry in 2014 is analyzed. It is concluded that the economic result of the use of management model at Russian industrial enterprises is extremely low and varies at most about 1% of revenue. The obtained results demonstrate the prospects of further development of lean production and prove the possibility of achieving a high competitiveness of the domestic industrial sector of economy.

Abstract
The advantages of neural network technology is shown in comparison of traditional descriptions of dynamically changing systems, which include a modern land market. The basic difficulty arising in the practical implementation of neural network models of the land market and construction products is revealed It is the formation of a representative set of training and test examples. The requirements which are necessary for the correct description of the current economic situation has been determined, it consists in the fact that Train-paid-set in the feature space should not has the ranges with a low density of observations. The methods of optimization of empirical array, which allow to avoid the long-range extrapolation of data from range of concentration of the set of examples are formulated. It is shown that a radical method of optimization a set of training and test examples enclosing to collect supplemantary information, is associated with significant costs time and resources for the economic problems and the ratio of cost / efficiency is less efficient than an algorithm optimization neural network models the earth market fixed set of empirical data. Algorithm of optimization based on the transformation of arrays of information which represents the expansion of the ranges of concentration of the set of examples and compression the ranges of low density of observations is analyzed in details. The significant reduction in the relative error of land price description is demonstrated on the specific example of Voronezh region market of lands which intend for road construction, it makes the using of radical method of empirical optimization of the array costeffective with accounting the significant absolute value of the land. The high economic efficiency of the proposed algorithms is demonstrated.

Abstract
In the Russian economy not every business entity, implements innovative business activities. The situation generated by the complexity of perception and practical transition to an innovative economic system. On the development of innovative activities affects the overall condition of the economy, condition of material production. The research demonstrates that resource potential of innovative activities in recent years had a tendency towards absolute quantitative reduction and quality deterioration. The decrease in the level and quality of resource provision of innovative activity due to the lack of necessary financial resources. Currently, innovation has become the primary means of increasing the profit of economic entities at the expense of better meet market demand, reduce production costs compared to competitors. Given the complexity of businesses, there is a need of the state stimulation of innovative activity, which is carried out the main directions, forms and methods. In the system of direct effects of the state on business innovation is the stimulation of development of Technopark structures. Creating the most favourable conditions for innovative enterprises, the provision of various services is their main goal. For the food processing industry currently, the largest share in the investments in the investment activities have their own sources of funding, including the use of depreciation. To Finance industry-wide, cross-sectoral and regional scientific and technical problems you can create extra-budgetary funds for financing R & d and innovation support. To encourage regional interests, one of which is that innovation is available to local authorities. In the financial provision of innovative activity is given credit. A Bank loan allows you to increase the efficiency of innovation activity. The article concludes that these measures to stimulate innovative-innovative activity can effectively influence the activity of the company: will allow to increase the production of food products of high quality and varied assortment, which in turn, would boost the earnings of the food industry.

Abstract
The article is devoted to the definition of the economic content of the concept of “investment attraction” and the study of the criteria of investment attractiveness. We conducted a retrospective analysis and systematization of the various definitions of “capital”, “investment”, “investment attraction”, given by domestic and foreign authors. A generalized definition of capital is given: “capital’ is an objective economic category, which offers a business entity to carry out its investment activities in order to expand the scope and value of the business, making a profit and improve its investment attractiveness. It is emphasized that the concept of “investment” is broader than the concept of “capital”: it is investment in capital with varying degrees of liquidity for the purpose of subsequent increments and increase the value of the business entity. The author defines the main characteristics of the investment. A distinction of the term “investment attractiveness” of similar concepts, “market attractiveness”, “investment climate”, “investment image”, “investment potential” is made. It is concluded that the investment attractiveness is a component of the investment climate, which is characterized by an objective character and eliminates the subjectivity. Based on the understanding of different approaches to the study of the investment attractiveness and define its criteria the author offers a brief description of the concept of “investment attractiveness”: investment attractiveness is an independent economic category – a set of internal and external factors, as well as qualitative and quantitative indicators of the investment potential of any of the levels of the economic system – state, regional, sectoral, level of economic entities. Evaluation of investment attractiveness at all levels of the economic system is carried out in the current period (current situation analysis) and forecast period (investment market forecast).

Abstract
Approaches are presented in the article, qualificatory the design of financial results on the basis of factor analysis. Connection marks between development of enterprises and scientific and technical progress. It is shown that potential of enterprises can be based on the design of financial results. Actuality of this direction of research marks on a background the entered approvals against Russia. A control role is indicated at the effective use of resources. It is well-proven that a key moment in forming of profit of enterprise is a design of financial results. A factor analysis is reasonable at the estimation of activity of organization, which exposed an application of this determined model domain. is sent to capital augmentation. The role of the financial system and separate elements is shown in to financially-economic activity. Connection is set between a design and structure of the investigated object. A design cannot come true without determination of structure of the investigated object, because a structure characterizes steady connections between elements. The components of elements are able in totality to counteract to external influences. For expansion of the system to distinguish the most meaningful factors. To distinguish integrating connections from appropriate. Distinguished, that factors due to co-operating with each other can create a synergistically or extinguishing effect or neutralize each other. Factors will organize or will disorganize work of organization. The design of objects is built on the certain terms, and separate parties of object are examined at abandonment from the less meaningful elements of the system. The role of empiric and theoretical level of research in the design of activity of organization is shown. An author suggested to use the determined model for determination of functional connections between a resulting index and factor signs. Exposed an application of this determined model domain.

Abstract
Modern Russia goes through a difficult period of crisis and exchange of sanctions that have left a definite imprint on the Russian players in the logistics market. Logistics, as a so-called satellite, the motor trade is in their systems a huge potential. It is a sort of “blood arteries of the country” – water, road, rail, air. Any changes in international economic relations are automatically projected onto the market of logistics services. This article discusses the position of logistics in today's economic situation, as well as methods and means of adaptation and optimization under these conditions. The article reveals the undeniable advantages of the WMS – system, and describes a method for effective solutions for cost optimization in logistics as a cross – docking. This article also describes the idea and in fractional reveals the essence of this method of cost optimization solutions. In the process of studying the article becomes abundantly clear that this system has a distinct advantage in the absence of the need for investment funds, the only necessity of the system is an effective HR management and monitoring processes. There is confirmation of the fact that in difficult times of crisis, logistics has a huge potential and opportunities for growth and optimization. We give evidence that the innovative WMS technology strengthens its position and deeper embedded in the system of logistics and cross-docking, in turn, is one of the effective ways of making cost optimization in logistics at this time in this situation.

Abstract
The article explains the concept of the company sustainable development strategy based on its economic security level, which includes the economic security concept loss threat control; and the concept of company sustainable development based on the fact, that the company in a developed market should not only "defend", but also ensure its development. After it implementation of decomposition is applied to the system of strategic economic security through a balanced scorecard, which allows translating the mission and vision into a set of operational goals and targets. The main components of strategic economic security provision are: business processes, finance, contractors and staff; based on the state which economic security level is determined as: high, normal, low or critical. After that, the strategic prospects are set, i.e. transition from the lowest to the highest economic security level takes place, passing the economic security fields. In order to do this, certain company development strategy is selected, the mechanism for its implementation is being worked out. At the same time, company sustainable development strategy is identified in the case of a growth strategy use, which implies a transition from endogenous development strategy to introductive or introspective development strategy with further access to multi-integral development strategy. If there is inverse relationship, one can not speak of any sustainable development strategy. Besides, development, implementation and use of monitoring for the design process of the company's development strategy taking into account its economic security level acquires great importance.

Abstract
The article considers the topical problem associated with the need to ensure the successful operation of enterprises through the development and implementation of the development strategy of enterprises of enterprises included in the integrated structure. Such a strategy can only be successful if they are coordinated with corporate strategy, integrated structure, and they will establish mechanisms for the implementation of linkages between enterprises, enterprises and the parent company. These mechanisms should be specially created in the parent company division (corporate center), endowed with appropriate powers. The article suggests the model of the corporate centre, adapted to the conditions of Russian integrated structures. As shown by the results of the study, among the analyzed companies belonging to JSC “Concern "Sozvezdie"”, only one has a strategy for the development, although it was designed for operation in stand-alone mode without integration with overall corporate strategy. In the electronics industry to coordinate the development and implementation of strategies for the development of enterprises, as a rule, the most commonly used structures for the integrated model “strategic controller”, however, to implement this model in relation to the activities of the corporate center with a positive effect appears to be doubtful by reason of the presence of “centrifugal process” in the mood of most business leaders, the absence of all shared corporate culture and information systems to provide control and centralization of part of the centralized functions, etc. In this regard, the authors proposed a new model for the corporate centre on the transition period of 2–3 years, which reduces the interference of the center in the work of enterprises of the integrated structure and to reduce the flow of accounting documents, requiring considerable effort and time of personnel.

Abstract
Electric-power industry has the great influence on the development of economy and status of the country in general. Its stability and reliability has a great effect on national economy and welfare of citizens. Electric-power industry in Russia experienced many reforms but some of the fundamental problems have not been solved and the level of its efficiency is still questionable. Nowadays most experts agreed that Russia and the whole world are on the threshold of energy crisis that is why one of the priorities of economic policy should be energy efficiency which is a way of reducing the consumption of energy resources by enterprises and households. These actions should be taken due to the necessity of reducing negative impact on the environment associated with consuming of energy resources and waste products of enterprises and increasing requirements for energy efficiency in today’s world. At present it’s rather hard to analyze electricity sector in Russia. Statistics from different official sources do not correspond with each other. Sometimes it is hard or even impossible to differentiate electric power from heat energy among all resources. All these facts and many other circumstances make the analysis of electric energy market very difficult. To increase the efficiency of electric-power industry in Russia several problems must be solved, among them environmental protection issues related to reduction of electricity producing in cost. Thus it will help us to prevent possible negative technological, socioeconomic and ecological consequences of certain operations. This article considers fundamental problems of electric-power industry in Russia, their possible solutions, and development strategy of this industry to 2035.

Abstract
Over a long period of reforms, political, economic and social situation in the Russian Federation has changed significantly. Formed during transformation of the Russian economy, economic relations provoked a change in established patterns of socio-economic behavior of the population that determined the need for significant changes in the system of social security of citizens, especially in the social protection of families raising children with disabilities. Over the past five years has taken significant steps to improve the legislative norms regulating the situation of children with disabilities, which served as the preamble to the achievement of certain positive results, however, economic and social support for families raising children with disabilities, remains low. Equally important is the fact that the appearance of a fundamentally new for Russia, economic, social and institutional relations in this field has necessitated the study of various economic foundations of social protection of children with disabilities. To date this subject, though its importance was not considered in scientific research that determines the relevance of this dissertation work, its scientific and practical importance. The article discusses the conceptual basis of the resource potential of social protection of children with disabilities in the framework of the modern economic realities of the state policy on social-the shield of the population. A key aspect of the research was to determine the qualitative and quantitative level of resources, required to fully meet all the needs of potential customers, that is children with disabilities. The syllogism of the study is to identify criteria for the effectiveness of the services provided to children with disabilities the use of the resource potential of bodies of social protection.

Abstract
The concept “Cluster” of domestic and foreign literature traditionally is considered as administrative and organizational education. At the same time he represents the social and economic object created for life support of the person. The cluster is considered as system object. The main signs are defined and his life cycle is considered. Cluster self-organization takes place stages: growth of organizational weight and effects, market threats and restrictions interfering growth of organizational weight. Development of clusters requires the state support in various forms which is offered to be carried out at various stages depending on his type. The cluster is considered as the economic system possessing an emergent which dynamic aspect is the synergy, the receiving multiplicative effect causing an opportunity. The quantitative assessment of size of the listed effects represents rather complex challenge, at the same time there is a number of the factors which are with her in directly proportional dependence. The synergy which is present at a cluster allows to gain social and economic effect of his functioning by means of integration of effects of all structural elements bigger, than their simple sum. The emergent in a cluster causes increase of productivity at the expense of innovations in technological and organizational spheres and stimulations of the birth of new businesses. The multiplicative effect arising in a cluster provides incremental nature of economic results. It is possible to refer the following to the main economic results received from creation and development of clusters: decrease in transactional and transformational expenses and costs of formation and further use of infrastructure, economy of costs of introduction and development of the high and innovative technologies, optimization of logistic and information expenses, increase of business reputation and investment appeal.

Abstract
Need of an assessment of investment appeal of projects, according to authors, is caused also by the fact that the investment project is the independent object of the analysis entering the general program of development, both the knowledge-intensive enterprise, and economy in general. Results of the investment analysis allow the potential owner to determine the term necessary for return of originally invested sum, to calculate real increments of assets from acquisition of property, to estimate potential stability to risks of the cash flow formed by concrete object of property. In article features of an assessment of investment appeal of innovative projects on introduction of information technologies are considered. Methodical approach to innovative development of the knowledge-intensive enterprise is created. Within this approach the main evaluation stages are defined, approaches to an assessment of a discountrate of the IT and innovative project are specified, calculation of key indicators of investment appeal of the innovative project is made. The offered assessment procedure of investment appeal of the investment project of introduction of information technologies will allow the enterprise to choose an optimal variant of implementation of IT solutions which will give the chance to solve the problems revealed during an assessment of his activity. Research is based on the theoretical and methodological provisions, classical and modern fundamental concepts which are contained in works of classics of economic and administrative science and also the domestic and foreign scientists working in the field of the organization and management, the organization and management of innovative development of the knowledge-intensive enterprises. For the solution of the tasks set in article the complex of scientific basic and applied theories, approaches and methods has been used, namely: theory of systems and system analysis, theory of management, theory of decision-making, theory of innovations, theory of cost and interested persons, process and system approach, and also methods of mathematical modeling, logical analysis and empirical research, etc.

Abstract
Living standards depends on the state of the country’s industrial complex. In a message to Russian President Vladimir Putin's Federal Assembly was asked to implement in 2015 a national technological initiative, the development of industries of the new technological order. As a result of the predominance of the industry of the sixth technological order should occur major changes in the structure of production factors and significance. It follows the inevitability of structural changes in the system of economic institutions and mechanisms of economic security and competitiveness of the state achieve the main goal of the state program “The development of industry and increase its competitiveness” is carried out through the following the directions of sub-programs: investment goods (chemical complex development composite materials, industrial biotechnology, power engineering, machine tool industry, agricultural machinery, machinery specialized production, transport engineering); goods (light industry, children;s products industry, the automotive industry); military-industrial complex; infrastructure (development of engineering activities, industrial parks); semi-finished goods and materials (timber industry, metallurgy, industrial development of rare-earth metals). At the current pace of technological and economic development, the 6 th technological structure will come into proliferation phase in 2010–2020, and in the phase of maturity – 40-ies of XXI century. At the same time in 2020–2025 there will be a new scientific-technical and technological revolution, which will become the basis for developing, synthesizing advances in the above basic technologies. In this paper, we proposed as a tool to ensure the economic security of the state to use the acceleration system of technical development of the industrial complex.

Abstract
The article considers impact methods on the economic results, the effectiveness of the regional economic complex should be based on a high quality of the basic characteristics classification of the region state. Application composition techniques to ensure a comprehensive impact on the achievement of this goal should in synthesized form to union, adopt a target orientation of development of the region with the parameters objectively revealing his condition. Ensuring organizational, economic, financial and investment techniques to achieve the planned targets and requires specifying align resource potential of the region with the available capacity of the regional economic complex to promote economic growth, improve the efficiency of operations. The main characteristics of the potential resource opportunities in the region are the skill level of workers, the degree of depreciation of fixed assets and their renewability, increased innovation in the region, its branches and facilities, strengthening of competitive advantages, the annual average number of employees, the cost of fixed and current assets, financial stability. In the region the opportunity to potentially affect the ability of its structural components to achieve the financial and economic performance targets acts as efficiency ability to provide stable dynamics of regional production efficiency, enhance the level of benefits to achieve the planned efficiency used (consumed) resource. Applying of certain methods or their entire structure, created to provide a comprehensive impact on the goal achievement, in the synthesized form of target orientation combines regional development with the parameters most objectively revealing his condition. Achieving the appropriate organizational, economic, financial, investment or other measures to achieve planned targets that are expressed by the level of efficiency of activity in the conditions of the most complete involvement and intensity of use in time of financial and economic potential of the region, perhaps on the basis of a high level of institutional capacity of the regional economic complex. The potential to support sustainable economic growth or an annual increase the efficiency of regional production is characterized by a set of indicators that reflect the economic-financial and organizational capacity in conjunction with the ability of the regional economic complex effectively is-enjoy the material-technical, labor and natural resources, has successfully positioned on and other international markets.

Abstract
The financial condition of the enterprise can be estimated by a set of characteristics (solvency and liquidity, structure of the capital, profitability, etc.). The part of financial coefficients is low-informative, and other part contains the interconnected sizes. Therefore for elimination of ambiguity we will pass to the generalized indicators – rating numbers, and as the main means of research it is offered to use the theory of expert systems. As characteristic of the modern theory of expert systems it is necessary to consider application of intellectual ways of data processing of data mining, or simply data mining. The method of immersion of a problem of comparison of a financial condition of economic objects in an expert cover in a class of systems of artificial intelligence is offered (algorithms of a method of the analysis of hierarchies, contiguity leaning of a neural network, algorithm of training with function of activation softmax). The generalized indicator of structure of the capital in the form of rating number is entered and the sign (factorial) space for seven concrete enterprises is created. Quantitative signs (financial coefficients of structure of the capital) are allocated and their normalization by rules of the theory of expert systems is carried out. To the received set of the generalized indicators the method of the analysis of hierarchies is applied: on the basis of a linguistic scale of T. Saaty the ranks of signs reflecting the relative importance of various financial coefficients are defined and the matrix of pair comparisons is constructed. The vector of priority signs on the basis of the solution of the equation for own numbers and own vectors of the mentioned matrix is calculated. As a result the visualization of the received results which has allowed to eliminate difficulties of interpretation of small and negative values of the generalized indicator is carried out. The neural network with contiguity leaning and function of activation softmax is applied to further smoothing of dispersion of indicators. Application of this method allows to facilitate considerably problems of interpretation of results of comparison of a financial condition of various enterprises.
