Abstract
At present, methods of drying dispersed materials in variable regimes, when not only the temperature and speed of the drying agent varies with time, but also the state of the material layer undergoes changes, due to controlled hydrodynamics in the working volume of the drying plant. Variable modes are used for drying in oscillating modes, with stepped hydrodynamic and temperature modes, and also when drying in an isothermal cycle. If oscillating drying with alternation of heating and cooling zones of the material and drying of the material in stepwise modes, first of all, is aimed at preserving the quality of the target product, then isothermal drying consists in preheating the material to the maximum permissible temperature with subsequent drying without reducing it during the whole process with a maximum rate of moisture removal. Reduction of heat energy costs in drying processes with variable heat supply is achieved due to the maximum heat recovery in closed thermodynamic cycles for the heat carrier, including using heat pump technology. Using the example of a multi-zone drum dryer, equipped with a two-stage steam compression heat pump, the possibility of a significant saving of heat energy costs during the drying of dispersed material without additional calorific heating. From the analysis of the drying process in the I-d diagram it follows that the utilization and heat recovery in a closed thermodynamic cycle by the heat carrier can reduce the specific energy consumption. An algorithm for controlling technological parameters in the field of permissible technological properties of the dried material is proposed.

Abstract
Models of many technological processes (drying, Smoking and drying fish) are described by equations. Such models and applies the model of drying process of raw materials for example wood drying. The article considered a model of drying of raw materials based on the heat equation with variable coefficients. Physical properties of wood during the drying process change, and therefore the equation coefficients are changed according to some given law. The model becomes essentially nonlinear. As a rule, to obtain the solution for such models explicitly impossible. In this case, it becomes the actual task of developing numerical methods for solving model equations and writing of appropriate programs for computer simulation of technological processes. The existence of such programs allows researchers to solve the problem of selecting the optimal parameters and the optimum conditions of the studied technological processes to determine the time required to achieve the desired values of the objective functions. Based on the calculation formulas developed simulation program of the thermal field in MatLab that can be used to simulate the drying process under different conditions. The article provides examples of model calculations for different values of parameters of raw materials. Processes associated with heating or drying of the feedstock, are observed when Smoking or drying fish. The suggested algorithm can be, after some modifications, used for their modeling.

Abstract
The extension of periods of storage of fruits of gourds is an urgent task processing industry. The most developed and available for injection is a method of dehydration of raw materials due to supply of heat transfer fluids. In addition to solid dry frame in raw materials is 80–90% water. In the period of moisture removal from raw material changes of thermal-physical and structural-mechanical and physicochemical characteristics. The ratio of water and dry matter in vegetative raw materials largely determines the modes of drying and storage conditions of the finished product. During drying, there are a number of limitations: the drying temperature should not exceed the degradation temperature of vitamins and proteins, and the magnitude of course, the moisture content of the product depends on the reaction prevention malonodinitrile sugars at the critical moisture content. An important problem of the drying of production is quality control stages of drying, the dynamics of which is quite difficult to describe using mathematical models.

Abstract
Forage production is currently undergoing a period of intensive renovation and introduction of the most advanced technologies and equipment. More and more often such methods as barley toasting, grain extrusion, steaming and grain flattening, boiling bed explosion, infrared ray treatment of cereals and legumes, followed by flattening, and one-time or two-time granulation of the purified whole grain without humidification in matrix presses By grinding the granules. These methods require special apparatuses, machines, auxiliary equipment, created on the basis of different methods of compiled mathematical models. When roasting, simulating the heat fields arising in the working chamber, provide such conditions, the decomposition of a portion of the starch to monosaccharides, which makes the grain sweetish, but due to protein denaturation the digestibility of the protein and the availability of amino acids decrease somewhat. Grain is roasted mainly for young animals in order to teach them to eat food at an early age, stimulate the secretory activity of digestion, better development of the masticatory muscles. In addition, the high temperature is detrimental to bacterial contamination and various types of fungi, which largely avoids possible diseases of the gastrointestinal tract. This method has found wide application directly on the farms. Apply when used in feeding animals and legumes: peas, soy, lupine and lentils. These feeds are preliminarily ground, and then cooked or steamed for 1 hour for 30–40 minutes. In the feed mill. Such processing of feeds allows inactivating the anti-nutrients in them, which reduce the effectiveness of their use. After processing, legumes are used as protein supplements in an amount of 25–30% of the total nutritional value of the diet. But it is recommended to cook and steal a grain of good quality. A poor-quality grain that has been stored for a long time and damaged by pathogenic micro flora is subject to mandatory processing. Among the most promising now include the technology of expansion.

Abstract
In conditions of industrial maintenance of animals, their health is noticeably weakening, in the majority of the body, profound metabolic disorders are noted, and productivity is reduced. In such conditions it is necessary to use feed additives in the form of briquettes-licks, able to compensate for the lack of micro and macro elements, vitamins and many other substances. Intensification of feed production through the use of new advanced technologies allows to improve the quality of products and reduce losses in its production. The technologies used for briquettes-licks and equipment for their production do not always allow to provide high quality products and achieve the necessary effect when fed. In addition, they are energy-intensive, do not imply the use of secondary energy carriers. Therefore, the creation of a functional product, combining a complex of substances necessary for animal feeding, and the development of an energy-efficient method for its production is topical. The proposed technology makes it possible to obtain feed briquettes with high homogeneity and a specified content of biologically active substances, to ensure a longer-term preservation of the products. The developed line provides for the maximum rapid cooling of the finished product and a reduction in the specific energy consumption for its production as a result of the heat of spent coolants. The high-quality licks produced were homogeneous in their composition, resistant to unfavorable conditions. They are characterized by a higher stability of structural and mechanical properties and stability of storage quality for a long time: after twelve months, the technological properties of the products have not changed, signs of damage associated with increased humidity of the environment have not been noted. On the surface of briquettes, signs of development of microflora were not observed. The values of microbiological quality indicators were within acceptable limits. The development of energy-efficient method of its production is relevant. The proposed technology allows to obtain feed pellets with high uniformity and specify the content of biologically active substances, provide a long-term preservation products. It gives the possibility of issuing briquettes with high quality. In the developed line provides the most rapid cooling of the finished product and the reduction of specific energy consumption for its production as a result of the use of waste heat coolant. High licks were homogeneous resistant to adverse conditions and maintain the structural and mechanical properties and quality for a long time .If stored for twelve months technological properties of the product have not changed, deterioration of symptoms associated with high ambient humidity, it is noted. On the surface of briquettes signs of microflora is not observed. Values of microbiological quality parameters were within acceptable limits.

Abstract
Grain of cereal cultures along with other types of nutrients contains much starch which digestion happens slowly and at the same time only certain forms and that in a small amount are productively used. According to a number of researches, the comprehensibility of nutritious potential of starch in the created natural form does not exceed 20–25% depending on a type of cultures. Therefore the problem of new technologies of processing of grain also consists in introduction of such ways of processing of initial raw materials which would allow to translate starch in convenient for assimilation by an organism a form. It is possible at destruction of granular structure of starch at the cellular level that promotes a rupture of natural communications between separate components and to his translation in more plain carbohydrates in the form of dextrins and sugars. Without special processing is trudnousvoyaemy as well cellulose which contains in a large number in grain and beans, especially in their top protective layers and covers. Therefore the developed ways of profound processing of initial grain raw materials have to promote destruction of a part of cellulose and lignin formations of cellulose in natural forms in simpler types of monosugars and amino acids. In world practice of production there is a set of methods and technologies of processing of grain raw materials for the purpose of increase in its nutritiousness. In recent years along with such receptions as extruding and expansion experts turn the increasing interest on methods of direct impact of electro magnetic fields on the earned extra raw materials. One of such processing methods is the method of electrohydraulic influence.

Abstract
Kinematic calculation is a mandatory part of the design of the flat lever mechanisms. This operation is very time-consuming and always need many calculations. Therefore, it is important to develop mathematical models for calculating the kinematic characteristics of the flat lever mechanisms, containing at least one double-leash Assur group. The article is devoted to mathematical modeling of five types of the Assur groups. The initial pin joint position and the driving ring kinematic characteristics used as an input for the further calculations. For the selected Assur group created the equation of motion in plane coordinates axis for the pin joints. With double differentiating the equations of motion were derived equations for determining velocity and acceleration of the pin joints in the global axes projections. The result of several transformations in matrix forms is the equations for the kinematic characteristics of the slave units in the selected Assur group. Finally, mathematical procedures for the kinematic characteristics of each double-leash Assur group were calculated. In a structural analysis of the complex planar mechanisms with a leading link and several double-leash Assur groups it is possible to determine the kinematic characteristics of all parts by consistently addressing the appropriate procedure. All suggested algorithms implemented as a software library that will speed up the designing of the complex planar mechanisms.

Abstract
The article is devoted to the development of the algorithm of the heating phase control of a rubber compound for CJSC “Voronezh tyre plant”. The algorithm is designed for implementation on basis of controller Siemens S-300 to control the RS-270 mixer. To compile the algorithm a systematic analysis of the heating process has been performed as a control object, also the mathematical model of the heating phase has been developed on the basis of the heat balance equation, which describes the process of heating of a heat-transfer agent in the heat exchanger and further heating of the mixture in the mixer. The dynamic characteristics of temperature of the heat exchanger and the rubber mixer have been obtained. Taking into account the complexity and nonlinearity of the control object – a rubber mixer, as well as the availability of methods and great experience in managing this machine in an industrial environment, the algorithm has been implemented using the Pontryagin maximum principle. The optimization problem is reduced to determining the optimal control (heating steam supply) and the optimal path of the object’s output coordinates (the temperature of the mixture) which ensure the least flow of steam while heating a rubber compound in a limited time. To do this, the mathematical model of the heating phase has been written in matrix form. Coefficients matrices for each state of the control, control and disturbance vectors have been created, the Hamilton function has been obtained and time switching points have been found for constructing an optimal control and escape path of the object. Analysis of the model experiments and practical research results in the process of programming of the controller have showed a decrease in the heating steam consumption by 24.4% during the heating phase of the rubber compound.

Abstract
The paper shows the general technology for designing a forest road route in space and the rationale for choosing the most effective method for specific conditions The experience of designing the track using the method of supporting elements showed its high efficiency, at the same time the opportunities for further improvement of the automated design process were revealed with the aim of completely eliminating the stage of graphic processing of the route and automatically recording all the requirements presented to it. To realize these possibilities, a study of the design of the clothoid route was carried out by approximating a sequence of points in the sketch line using nonlinear programming methods (abbreviated name is the method of approximation of a sequence of points). The idea is to determine the position and all the geometric characteristics of the clotoid path, corresponding to the requirements for it, by corresponding processing on the computer of the mathematical model of the sketch line. In this case, the trace should best approximate the specified sketch line, i.e. Geometrically incorrect approximate route. The sketch line can be obtained automatically, for example, using the method of designing the optimal "chain" route, or it can be scheduled by the designer using aerial photography materials or topographic plans, based on economic and other considerations, and entered into the computer's memory using automatic coordinate recorder.

Abstract
The tracing of individual logging roads is part of a more general task - the development of a scheme for transport development of the enterprise's forest raw material base. As a result of its solution, the location of the main transport routes - highways and branches - is determined in the forest, taking into account the optimal distances between the branches. When establishing these distances, account is taken of the costs of forest management measures, referred to the total volume of timber, tending to the branch. The search for a variant of the track of a timber logging road close to the optimal for one of the criteria for the removal of the concentrated volume of timber is carried out in several stages. First, the optimal route variant is inscribed, inscribed in the grid of squares of the digital terrain model (the route passes along the sides and diagonals of squares). Then the found variant is smoothed with broken lines located in its vicinity. For each of the smoothed variants of the route, fourteen important technical and economic indicators are automatically calculated, allowing to make an informed decision when choosing the final version of the route of the future road. The accuracy of the construction of the digital relief model on a topographic map using the developed technique was estimated from the reference longitudinal profiles taken manually from the map in contours and built automatically using a digital terrain model. The results of the comparative analysis testify to the quite satisfactory accuracy of the developed method of manual digitization of maps. With the help of the same reference longitudinal profiles, it is possible to control the correctness of the results of digitization. To do this, it is sufficient to draw several rectilinear segments intersecting the simulated section in different directions and compare their longitudinal profiles constructed on the map with automatically calculated.

Abstract
At the Food Production Department of Murmansk State Technical University (MSTU) was developed a technology of production of smoked fish products with the use of air-flue mixture, produced in an infrared smoke generator under conditions of low-temperature pyrolysis of wood chips with an initial moisture content of 40 to 60% and a bulk density of from 104 to 154 kg/m3. A method of producing smoke and its hardware design enabled to securely control the temperature of the smoke receiving smoking environment, which guarantees a minimum content of threat to human health of polycyclic aromatic hydrocarbons (РАНs). The developed technology involves short cycle smoked salted semi – fish fillets and allows to obtain finished products with excellent organoleptic properties. The content of РАНs in finished products less than 0.0002 microgram/kg, which is significantly below the maximum permissible concentrations (MPC) according to the requirements of SаnРiN 2.3.2.1078 (less than 0.001 mg/kg product) and according to the requirements of TR CU 021/2011 (0.005 mg/kg product). This technology successfully implemented in production at fish processing plants in Murmansk region. However, marketing research has shown that the market for smoked fish in the Murmansk region is characterized by a narrow range, which affects consumer demand and reduces the competitiveness of the regional enterprises-manufacturers of smoked products. To solve this problem it is offered to expand the range of smoked fish products due to use of non-traditional Smoking techniques raw materials – fillet of cod fish (saithe, haddock, cod). To improve consumer properties of products, in particular, to improve the indicator of “consistency: and "juiciness" of the proposed use on the stage of the salting of prefabricated enzyme preparation from hepatopancreas of snow crab (Chionoecetes opilio), added to brine with density of 1.18 to 1.2 g/сm3 at a dosage of 0.04%, the curing time of the mix in the brine for 15 minutes. When optimizing technological regimes of the salting process with the enzyme preparation we used the method of fuzzy modeling implemented in the MatLab calculating software.

Abstract
There are one of ways to save peoples heath is eating food, what rich in fiber. To the recovery of polyunsarurated fatty acids, protein, mineral substances, fibers it recommended to eat flax seeds and its products. One of these products are flaxes. The purpose of the work was a rational choice of the duration of soaking seeds, providing strong reception of finished products. Founds that when hydrated of 10 to 30 minutes of the study setting almost unchanged. After 30 minutes soaking the tensile strength increased, and then decreased. The maximum value observed in the samples in which lasted 40 minutes soaking. Probably, due to the fact that upon contact with water 30 minutes before the moisture is adsorbed on the surface of flax seed are thus formed in a small amount of mucus. From 30 to 40 minutes soaking carbohydrates undergo hydrolysis inner layers of the endosperm and seed shell. While the water absorption capacity of flax reaches limits. Also increases the amount of mucus, and after 40 minutes soaking becomes excessive, resulting in reduced tensile strength of the finished product. Therefore, rational while soaking flax 40 minutes, providing the maximum value of the parameter under study. Flux thus, thanks to the ability of flax seed soaking and store slime forming after drying alpha-linolenic acid is a source of polyunsaturated fatty acids, dietary fibers, vitamins, minerals.

Abstract
Currently, there is another stage for increased interest in improving the quality and expanding the range of soft drinks and beer with the release of new titles due to the attraction of alternative types of plant materials, including technology-based ingredients and formulations – powdered malt extracts of various cereal crops – barley, buckwheat, peas, corn. X-ray diffraction experiment is one of the most accurate methods for studying the structure of matter at the atomic and molecular levels. X-ray diffractometry allows, the first, to determine the characteristic interatomic distances in matter from the position of the peaks in the diffractogram and to identify them-to estimate the given distance between atoms of different elements. Secondly, the width of the diffraction peaks can be used to estimate the degree of ordering of the structure and determine the characteristic dimensions of polymer formations. Thirdly, X-ray diffractometry makes it possible to evaluate the composition of a mixture of substances based on the comparison of diffractograms from the substances to be mixed. For the first time the comparative investigation of structural mechanical properties of powdered malt extracts with the assessment of solubility by X-ray diffraction analysis is studied. The main interatomic distances in the extracts are identified; the comparative X-ray diffraction study of the extract from peas, barley, buckwheat malt, prepared without introduction of molasses during drying were carried out. Calculation gives the following sizes of areas of coherent scattering for the extract L = 56.07?10-10 m; for the extract with molasses L = 7.470?10-10 m, in consideration with the calculated indicator of substance solubility with a characteristic size of the particles. It was found that the addition of molasses during drying allows to increase the solubility in 1.7 times. This statement is based on the comparison of the X-ray diffraction peaks of patterns and accounting of the size effect of solubility, and it was corresponded with the data on the solubility obtained by the standard method.

Abstract
Chocolate it’s popular confectionery product for children and adults. However, excessive consumption of chocolate adversely affects to human health due to high content of simple carbohydrates, especially sucrose. At Department of Technologies grain processing, bakery, confectionery and pasta production in Moscow State University of Technology and Management. K.G. Razumovsky developed a recipe for chocolate with natural sweeteners, such as stevioside and erythritol. Stevioside is a glycoside extracted from a stevia plant. Thanks to thermal stability (destruction occurs at 190–200 °C) it can be used in the traditional technology of chocolate production. Erythritol (erythritol) is a polyhydric sugar alcohol, produced from corn. Main difficulty of chocolate production with natural sweeteners on traditional way is - replacing sucrose with stevioside and erythritol in finished chocolate, a specific bitterness appeared, elimination of which became the main task of research. The obtained sample is characterized by maximum approximation to traditional taste, it does not have a side effect of using sweeteners - bitterness and a specific aftertaste. According to organoleptic and physicochemical parameters, it is close to classical dark chocolate, and also exceeds by more than two times average value of antioxidant capacity by lipophilic fraction, compare with well-known chocolate producers in Russia. This may be a consequence of increased content cocoa products in prototype recipe of chocolate sample, in comparison with traditional brands, with exclusion of sugar from recipe and replacement with natural sugar substitutes.

In experiments was used a dilatometric technique. The polymerization was carried out at different temperatures (60, 80, 100 °C for styrene and 40, 60, 80 °C for methyl methacrylate). Determination of molecular weight of the styrene and methyl methacrylate were produced on the basis of measurements of the intrinsic viscosity of its solutions in toluene. Analyzed kinetics of radical polymerization of styrene and methyl methacrylate in the presence of initiating agents, benzoyl peroxide and DOPA, benzoyl peroxide and DОPT. Determined kinetic parameters of the polymerization of vinyl monomers in the presence of new catalytic systems. The rate of polymerization significantly depends on the concentration of the initiating agents. At high amine concentrations that exceed the peroxide content, there is a rapid expenditure of benzoyl peroxide. Established that tertiary aromatic amines oxopropylidene affect the increase in the rate of initiation of radical polymerization at moderately low temperatures. The proposed mechanism of radical polymerization of vinyl monomers in the presence of initiating system benzoyl peroxide DOPT.

Abstract
Recycling rubber waste and improving of the efficiency of the secondary elastomeric materials use is an important technical and economic challenge. Vulcanized rubber waste is the most difficult to recycle. One of the promising ways of recycling waste vulcanized rubber is their grinding and subsequent use of the obtained powder as a filler in elastomeric compositions. The influence of the nature of ground vulcanizate (GV) on the properties of elastomeric compositions based on nitrile-butadiene rubber is studied in the paper. GV of two types are used for the investigation. The first type is tire based on non-polar rubbers of general purpose. The second type is obtained from wastes of production of industrial rubber article (IRA) based on polar nitrile-butadiene rubber. Particle size of GV’s fraction used in study is 0.63–1.00 mm. GV was input in unfilled model composition based on nitrile-butadiene rubber in dosages 50, 100, 150 and 200 phr. It is found that Mooney viscosity of the elastomeric compositions filled with GV of IRA wastes increases more than using the tire GV. The rate of stress relaxation in the uncured compositions are not depend on the nature of GV. The cure optimum of the composition containing GV-based on polar rubber smaller than GV based on general purpose rubbers is used. The influence of the ground rubber type and dosage on the cure network structure are investigated. the density of cross-linking of the vulcanizates decreases with increasing dosage GV. Vulcanizates filled with GV derived from IRA have higher cross-linking density than those containing tire GV.

Abstract
The development of effective separation schemes for oil refining products is an urgent task for modern industry. Clean and super pure materials are the main requirement of modern productions. The implementation of modern technological processes in the petrochemical and oil refining industry requires highly efficient devices, to which high demands are placed on ergonomics, economy, manufacturability and reliability. The effectiveness of the mass-exchange apparatus depends on the conditions of the technological process, the physical properties of the contact phases, taking into account the nature and amount of mechanical impurities circulating in this system. Therefore, the evaluation of the efficiency of mass-exchange devices with different types of contact devices, in order to identify their optimal technological and design parameters, is quite a difficult practical task. The application of a mathematical complex for the evaluation of the efficiency of mass exchanging apparatuses makes it possible to select the optimal operating modes and the design of a column disk apparatus necessary for efficient separation of the mixture. Dependences of the mass transfer coefficients in the gas phase and the efficiency of the Murphy sieve plate are presented, depending on the gradient at different gas velocities in a columnar apparatus for a sieve tray. An increase in the gas velocity reduces the effect of the uneven distribution of the liquid and gas (vapor) on the mass transfer coefficient in the gas phase, and at a gas velocity of 1 m/s and higher, there is no. A 40% reduction in the mass transfer coefficient in the gas phase is observed at a speed of 0.2 m/s, and at 1 m/s - by 1%. Increasing the gradient increases this effect. The decrease in the efficiency of the plate-type mass transfer apparatus by 5–35% used in petrochemical production is due to the gradient of the liquid level, as well as the type of contact device and the gas velocity

Abstract
The complex estimation of state of sugar-beet complex of the Russian Federation has been made. The basic indices of sugar beet production and processing such as area under crop, yield, croppage, sugar content, forecasted sugar yield, and production of sugar from beet are presented. Particular attention has been given to the analysis of sugar-beet industry of the Central Federal District and its separate regions. A high potential of raw-material base development in Central Federal District and, in particular, Central Black-Earth Region has been revealed. Thus, in Russia, about 53% of sugar beet sown annually is located in Central Federal District. In the District, areas under the crop were 607.4 thousand hectares in 2016 and increased by 8.7% in comparison with 2015. Also, in the structure of croppages, Central Federal District has the greatest position as providing 58.5% of overall production, and the Central Black Earth Region рrоduсеs 88–89% of the District sugar beet croppage. Over the period of 2005–2014, Central Federal District has surpassed Privolzhsky Federal District by 23.3% and Siberian Federal District by 25.3% in sugar yield per 1 hectare; but it is slightly inferior to Southern Federal District and North-Caucasian Federal District in this respect (by 3 and 12.6% accordingly). These achievements were promoted by favorable soil and environmental conditions during vegetation and harvesting of sugar beet, perfection of the crop cultivation technology and modernization of sugar industry. On the whole, Russia is the leader in beet sugar production (5 million tons) that provides 90% level of self-sufficiency. Strengthening of material and technical base, as well as development and introduction of resources-economy technologies can become the priority directions of the sugar-beet complex steady development in an effort to realize the policy of imported products substitution.

Abstract
Among the priority directions of the development of the alcohol industry, the development of energy and resource-saving technologies for ethanol production from grain is currently in the forefront. To obtain and fermented sugared grain must, starch and other components of the raw material must be transferred to a dissolved state. The choice of modes and technological parameters for obtaining sugared wort during the development of new technologies for ethanol production is based on economic and instrumental-technological aspects of production and is largely determined by the properties of the processed raw materials. In this regard, the need to develop new technologies that take into account the composition of protein substances and non-starch compounds of various types of grain raw materials, with the purpose of efficient bioconversion of all constituents of grain, which not only intensify the process of alcoholic fermentation and increase the yield of alcohol, but also obtain fodder protein Products is timely and relevant. To study the effect of enzymatic preparations containing xylanase, ?-glucanase and cellulase, as well as the thinning, saccharifying and proteolytic effects on the characteristics and viscosity of the wort, the aim was to obtain a highly concentrated wort from an aqueous-powdery wheat suspension. Application as a thinning preparation Termoferm 3500 L allows to obtain wort with the maximum concentration of solids, fermented carbohydrates and reducing sugars. At the same time, the indicator of apparent goodness of the wort when using Thermoferm 3500 L was 85.8%. The dependence of the flowability of starch wort on the duration of hydrodynamic and enzymatic treatment at the stage of mechano-enzymatic treatment was studied. As a result of studying the rheological characteristics during the preparation of starch wort, an effective, simple technological method for reducing the viscosity of media, namely, raising the temperature of water during batching from 50 to 70 ° C, could be propose.

Abstract
Traditional crops for malt production are rye, barley and wheat. Gluten-free and oats are considered to be gluten-free crops and recommended for use in dietary nutrition for patients with gluten intolerance. Increasing the range of gluten-free products is one of the most important conditions for improving the standard of living of people suffering from celiac disease. The influence of the duration of germination and drying on the amylolytic, saccharifying, proteolytic activity of buckwheat and oat malt with the purpose of improving the technology of creating a gluten-free product is given in the article. In buckwheat malt, the maximum value of amylolytic ability (AU) is 21.2 U/g, which is 6.0% higher than that of rye grain. In the case of oat malt, AU was 18.79 units/g, which is 6.0% lower than in traditional crops. The maximum accumulation of saccharifying capacity (OS) in all malts occurs on the third day of germination and reaches the following values: in rye malt – 5.1 units/g, in buckwheat – 2.9 units/g, in oatmeal 3.3 units/g. Compared with the traditional culture of buckwheat OS lower by 43.1%, oats by 35.3%. The maximum values of proteolytic activity (PA) of malts were achieved on the third day of ration: in rye – 23.2 units/g, in buckwheat – 26 units/g, in oats – 16 units/year. Compared to rye grain, PA buckwheat is 12.0% higher, oats lower by 31.0%. It was found that the enzymatic activity of malt, obtained from gluten-free raw materials, is lower than in rye malt, therefore it is not possible to completely replace traditional raw materials without additional application of the enzyme preparation.

Abstract
The article suggests innovative model for assessment of labour market subjects’ competitiveness, or successfulness. The authors state that general complex indicator for individual competitiveness within the labour market cannot be identified. Instead, precise enough assessment of such competitiveness can be based on some variables, though different for in-house and external labour market. The model of latent variables’ assessment based on Rasch’s method was selected as the base for the suggested method. The assessment model gives unbiased generalized values of subjects’ competitiveness on the linear non-dimensional scale based on the partial estimates of the selected criteria. The free choice of these criteria allows the model’s appliance for various labour market segments. The article demonstrates the mathematical grounding for the model; methodic of the assessment criteria selection; the way of assessment performance using MS Excel. It also analyses the features of the obtained estimates and shows their comparison with the estimates obtained by traditional methods. The model suggested by the authors can introduce any quantitative parameter of competitiveness as a variable after analysis of the factors affecting it. The quantitative estimates of these factors become the model’s criteria, but the assessment precision does not alter.

Abstract
The article deals with the concept of motivation of effective activity of the staff, under which the authors have in the form of activity of employees, aimed at achieving personal and organizational needs. The authors distinguish between the concepts of stimulus and motive, while under the first definition they mean the achievement of here and now goals. Different approaches to the theory of motivation are considered, which testify to the need to take them into account in production activities and in the system of personnel security, as well as different levels of employee motivation classification, such as nuclear – an especially important and immediate need of the employee, compensating – an important but not a priority for the employee, organizational. Combining the first two, the background one is important for the organization, but remote in time for the employee. The model of distribution of employees, participants of the project organization depending on the performance of activities on the stages, taking into account the three criteria – material incentive (nuclear demand), competency of the performer (compensating need), time motivation (background requirement) is offered. The analysis is justified by the influence of motives of a different-level order, reflected in the growth of labor productivity, the reduction of administrative and managerial expenses, increased involvement of workers in activities related to improving working conditions, the accessibility of managers to a broader base of talented professionals, the ability to employ people living in remote places . It is pointed out that a long-term motivation can meet not only the immediate needs of the employee, but also be a background requirement, when, without having the opportunity to increase the salary to the employee, the head can motivate the employee with a convenient working regime. Studies on the need to take account of background needs. A matrix of integral coefficients has been obtained, the elements of which indicate the need to use differentiation in the project activity of the organization for the levels of motivation of each employee. The authors proved that it is necessary to prioritize nuclear, compensating and background needs, which serve as the basis for the employee's motivational profile; he is individual for each employee.

Abstract
In the context of the weakening economic development of the region, it is necessary to find new ways to increase the efficiency of interaction between the economic structures of the region. One of the areas is the development of integration processes in the field of cooperation between the public and private capital to meet the goals and objectives of the effective functioning of both the participants of integration interaction, as well as the region as a whole. Factors that influence the emergence and development of integration processes, are a scarce resource; motivated by the need to diversify the business; the desire to improve the economic efficiency of business entities. Development grace-integral process is economic interaction managing subjects, followed by combining them to achieve common objectives and obtain the synergistic effect due to a number of resource solutions, organizational and administrative problems. To obtain high economic benefits of integration interaction of the participants, we have proposed a mechanism for the development of integration processes in the region, based on three levels of interaction between regional authorities, educational institutions and private organizations. It allows forming a single chain integration and process management to increase the effectiveness of their implementation in practice, and to avoid the disadvantages associated with the formation of the integrated structures. Integration cooperation of regional authorities with organizations of various spheres of activity of the region and education (research) organizations is a key component of the new Russian innovation policy because, if done right, it provides broader benefits from investments in research and development, creating favorable conditions for sustainable innovation development and is a strategic factor in the economic growth of the region.

Abstract
In this article is based dependence of country economic safety from development of innovative process in economics. Are distinguished three important inside factors which present threat to economic safety of Russia. These factors are connected: with aggravation of condition of country scientific-technical potential; with threat of origins of social conflicts from imperfection of labor payment mechanism, from increase of unemployment, from deterioration of quality and standard of education; with imperfection of legislation law and law enforcement. For removal of these threats it is necessary qualitative change of factors of production and human capital. Qualitative and quantitative indexes of human capital in many respects are formed both innovative activity in country and economic increase. The environment, in which is accomplished innovative activity, can ensure or hinder development, therefore it is in need of management. For this environment itself of innovative activity it is necessary to consider as economic system. As innovative environment in Russia only begins to be formed and taking into consideration instability of country economics, is found in unbalanced state, then processes of functioning as system it is necessary to consider from position of synergetic. Management of synergy process makes sure through institutional and economical activity of man. In search of ways of management quality increase, including innovative environment, ought to take into consideration synergetic effects both positive and negative, which can appear in creating innovative system and use them. The most important factors of innovative environment development are: standard of development of education, of science, relations between them and connection with production. Basic for way out from modern crisis is economic mechanism, in order to launch this mechanism necessary instruments of influence, between them important role play jurally means. Economic means of regulation of economics and of employer`s activity are not able to exist and to realize out of legal state regulation. At present the environment of innovative activity in Russia are in immature condition that hinders innovative development. Are required active managing actions from party of state structures for formation and development of innovative environment.

Abstract
The principles of social partnership when changing the bases of social and labor relations become an important element in the work of the modern leader. In Russia, on the part of the state for 2016–2021 years, it is planned to form a new model for the sphere of labor relations in the form of effective cooperation between employers and employees through the introduction of innovative principles. In conditions of objective competitive restrictions, the implementation of the principles of social responsibility is difficult. Toughening of legal norms with regard to the responsibility of managers in the system of collective social and labor relations, on the one hand, is intended to reduce the share of offenses in the organization of labor remuneration, unjustified its differentiation, on the other, reduces the management motivation caused by the increased risk of such liability. The social responsibility of the enterprise manager as a phenomenon alters the content of the mechanism of its distribution. Providing the Russian economy with highly competitive jobs implies a significant increase in labor productivity, therefore, the growth of wages and staff development is stipulated. Effective leadership aimed at the strategic development of the enterprise, not in all situations is able to solve unstructured tasks, even with sufficient attention to the staff and the right style of behavior. The tool for implementing strategic goals in this case is the personnel policy of the enterprise, which is proposed to be implemented in accordance with the developed professional-qualification model. The growth of the efficiency of the enterprise should be ensured with the use of internal reserves without attracting new personnel due to the renewal of production capacities, retraining of the staff for the purpose of acquiring higher skills and the ability to efficiently and efficiently employ flexible employment.

Abstract
The article discusses the new policy of import substitution in Russia. The replacement of imports by domestic counterparts is a priority of Federal and regional authorities. Innovative management should primarily take into account the new economic conditions which exist and will soon operate a food company. Describes the factors that have a negative impact on the efficiency of innovative management of dairy plants: the drop in oil prices, decline in exports, domestic oil prices, the devaluation of the ruble. The analysis of the indicators of import dependence and import substitution in the dairy group food. The analysis of indicators of the food industry showed that the indicator of self-sufficiency in the last 10 years have been below the 0.90 standard. In 2007, the industry reached self-sufficiency ratios 0.8146 that is still below the required standard more than 10%. These calculations allowed us to attribute the production of dairy products to import-dependent food industry. Therefore, in this industry were conducted further research based on the indicators “import” and “self-sufficiency”. Used methods of statistical control showed that the inverse correlation between these indicators does not exist. So, the volume of the imported imports depends on other factors and only increasing their own production, this figure does not decrease. Therefore, in the production of milk and dairy products need more reforms to improve the indicators of self-sufficiency. Providing the population of our country milk and dairy products in need of rapid change to increase its own production of dairy products. Thus, features of innovative management of dairy enterprises are determined by the modern conditions of import substitution.

Abstract
Small and medium-sized enterprises are characterized by maneuverability, readiness for change, and focus on innovation. But the growing instability of the external and internal environment requires the company to develop increasingly complex control systems. There were several models of management: by objectives, by processes and by changes. Achieving the goals involves the development and implementation of strategy and tactics. In business, strategy comes from the goal set by the owner before the organization. Process management describes and defines the main elements and categories of the process, observing the balance of responsibility and authority by creating a team to improve each business process. Management of changes is a special mechanism for the adoption and implementation of adequate management decisions. The article compares these management models, examines the criteria, indicators and factors for assessing the effectiveness of management of the organization. Comparative analysis showed that management of changes is more preferable for small and medium-sized businesses. Management of changes involves obtaining a certain idea of future trends in the development of the organization and the active use of entrepreneurial structure of modern management methods. This will ensure the economic stability and stability of the organization. Evaluation of the effectiveness of the enterprise can be carried out in accordance with performance indicators. The article suggests a matrix of selection of such indicators taking into account the sphere of influence. Recommendations are given on the choice of indicators of the effectiveness of achieving the goals. Also, the values under which the enterprise acquires stability of such key factors of management effectiveness as efficiency, capacity and sustainability of the organization are indicated. The theoretical and practical significance of this research is the development of methodological and instrumental support for the successful implementation of management decisions of the change management model.

Abstract
The implementation of innovative-oriented processes of transformation of the Russian economy at the current stage of development requires the formation of regional innovation systems that predetermine the growing competitiveness of the national economy in the future. The optimal functioning of the innovation system of the region as the most important link in the national innovation system depends on the availability, condition and level of development of its innovative potential, which in turn determines the economic growth of not only a single region, but the country as a whole. The essence and structure of innovative potential of organizational systems are considered in the article. The main approaches to the definition of the concept of innovative potential and the definition of the content of the concept are analyzed. An approach to the formation of an integrated indicator is proposed. The integrated indicator of the region's innovative potential was calculated using the area diagram method. The values of the innovation potential for the regions of the Central Federal District were calculated and the ranking of the regions was performed in accordance with the final value. Conclusion. To build a model for innovative development of the region, it is necessary to analyze the components of the innovation potential, its evaluation, and a possible development forecast for the coming years. Voronezh, Tula and Kostroma and Belgorod regions have high rates for the Central Federal District. Ryazan, Smolensk and Kostroma oblasts have rather low indicators in comparison with other regions.

Abstract
In the article the directions of expansion of the complex approach to the assessment of the influence of the external environment on the regional socio-economic system are considered. The authors propose an approach based on mathematical modeling of the main indicators of the development of the region. Empirical data for the development of models has become the departmental expenditure structure of the Bryansk region of the Department of Economic Development and the indicators presented for the development of the forecast of the socio-economic development of the Russian Federation for the period until 2019. When forming a model of indicators of socio-economic development of the region, approximating functions were obtained, limited by the range of specified values of departmental expenditures of the budget of the Bryansk region for 2012-2019. And acting as an interpolating relationship. For the optimal selection of the parameters of the equations, the method of least squares was used. Practical implementation of the conceptual model for assessing the impact of the external environment on the regional socio-economic system determines the need for its automation. The information advisory system developed on the basis of the presented model will allow to automate the process of supporting the adoption of the management decision. The obtained model for assessing the influence of the external environment on the regional socio-economic system is an information and analytical system for monitoring the regional situation as the basis for subsequent management decisions.

Abstract
The organic products market and the demand for quality products in the world are growing rapidly. In Russia it is only being formed. The European Union has an efficiently functioning system for regulating the production and use of organic products. The purpose of the study was to compare the current European and domestic legislation in the field of organic agriculture to develop proposals for the further improvement of domestic legislation, which will contribute to the development of the organic products market. The author used methods: abstract-logical, analysis, comparison, induction, deduction, monographic. As a result of the research, the author came to the following conclusions: at present, the regulatory and legal system for regulating the organic products market in Russia is a set of laws, standards, requirements not only Russian but also international. It includes both special legal acts and general economic ones, as well as federal as well as regional ones. Formation of the legal field in this area occurs during the economic crisis, sanctions and unsanctions, the country's membership in the WTO, etc. On how quickly its completion will depend on the position of Russia in the international organic market. In Russia there is still no law coordinating organic production. Adoption of the law on the production and circulation of organic products will ensure the development of ecological farming, as well as the production of quality and safe food. The development of forms and methods of state regulation of the organic products market will create conditions for the evolution of organic farming and farming in Russia, which will ensure that not only citizens of the country will be provided with environmentally friendly products, but will also provide an opportunity for domestic organizations to become full-fledged players on the international organic market. The results obtained by the author, in the future can be used by market participants of organic products in practice and the government in the development of special laws and by-laws.

Abstract
The article is devoted to the actual topic of our time – the management of business risks. 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 under development, the problem of a clear comprehensive definition of risk becomes now of particular relevance. The article discusses the basic concepts of risk management; studied its components in the business activities; reflected system and risk management principles; The basic types of risks in business. A organizational and economic mechanism of enterprise risk assessment. Practical advice on risk management. Entrepreneurship without risk does not exist. With the development of market economy the specific entrepreneur determines the methods that will work, and they all lead to entrepreneurial risks. The level of threats on the market today, above the level of potential profits. It is concluded that it is impossible to increase revenue without increasing the risk or reduce risk without reducing income. The lower range of the probability distribution of expected returns relative to its mean value, the lower the risk associated with this operation. Avoid risk in business is almost impossible, but you can reduce this risk. And it depends on how professionally and correctly operates the entrepreneur, what kind of strategy he will choose to reduce the appearance of risk.

Abstract
The article deals with the practice of evaluation of international investment projects using the cash flow discounting rate. The problem of the discount rate manipulating is connected with the category “country risk”, which often determines the impact on the rate and, accordingly, the investment decisions. Critically examines existing approaches to the definition of “country risk”. Categories that make up a complete picture of “country risk” are distinguished. The general defect of existing country risk concepts is revealed – the fact that the measurements are based on rather subjective assessments and do not have sufficient empirical evidence, the fact that almost all of them have a clear liberal democratic bias: as a rule, drawing attention to the relationship between the political system and stability, the liberal democratic structure of society is recognized as the most stable, without any acceptable scientific evidence, followed by autocracy, military dictatorships and new independent states. The author affirms the lack of a clear and unambiguous definition of this category, the controversial approach to ranking of countries. The author analyzes and proves the bias of rating assigned by foreign companies. As a conclusion the need to create a national research concept of the “country risk” category is аffirms with the subsequent promotion of national rating agencies to the world market. The author's conception of the category “country risk” is proposed, an author's definition is given to this notion, it is recommended to establish the primacy of national ratings over foreign ones both in domestic and international relations in order to have independent influence on international capital flows. It is also proposed the evaluation of projects based on the dynamic discounting rates, especially for long-term strategic projects.

Abstract
The level of development of state control points to systemic problems of state administration and affects the state of economic security in the region. The author conducted a study of the Russian practice of internal control and internal audit in the public sector. The functions of internal financial control duplicate the functions of line management for operational management. Internal financial audit means the audit of the financial and economic activities of the institution. Comparison with the provisions of conceptual documents and standards has made it possible to identify that internal financial control and internal financial audit does not fully correspond to the representations of these documents. The author substantiated the need to transform internal financial control in internal control, internal financial audit into internal audit. The author proposed to supplement with the specialization “Economic and legal support of economic security in the public sector” specialty 38.05.01 “Economic security”.

Abstract
In article the basic provisions allowing to create the capacity of scientific-industrial complex are considered. The scientific-industrial complex makes release of innovative production by means of realization of the cyclic carried-out process on carrying out applied - research and development, the organization of mass production., implementation of the analysis about results of operation of an innovation by the end user. The decision on production is made on the basis of the analysis of the request for performance of works by the enterprise submitted in the form of the bespoke. As a rule, volumes of activity of scientific-industrial complex allow to realize at the same time several bespoke created in a package. The volume and character of orders depends on the capacity of the enterprise and its scientific specialization. For definition of the key provisions on the organization of activity of scientific-industrial complex influencing a possibility of use of capacity of the enterprise the algorithm of selection of bespoke is considered. Comparison of requirements to realization of works on the order to opportunities of capacity of scientific-industrial complex, allowed to establish a number of the factors influencing efficiency of activity of the enterprise and use of its potential. The first such factor is ability of scientific-industrial complex to carry out scientific and applied activity of a certain thematic direction. Similar "specialization" of the enterprise allows to reduce costs and time for performance of work, increasing thereby resilience of the organization. The second factor is presence at scientific-industrial complex of the corresponding set of the resources necessary for performance of work by bespoke. The third factor is ability of the enterprise to realize the "potential" bespoke allowing to receive a reserve on works in the future. Realization of a similar reserve is possible thanks to consistently arising interest at the customer in results of activity of scientific-industrial complex.

Abstract
Of particular importance in modern conditions is the transition to financial management based on the analysis of the financial state, taking into account the setting of strategic objectives of the enterprise, adequate to market conditions, and searching for ways to achieve them. The maximum validity of the managerial decisions made is provided only by a qualitative analysis of the financial condition of both their enterprise and current and potential business partners. In this case, not only the current financial condition is important, but also the forecast for the near and distant future. Financial situation is the most important characteristic of business activity and reliability of the enterprise. It determines the competitiveness of the enterprise and its potential in business cooperation, is the guarantor of effective economic activity, both the enterprise itself and its partners. The financial condition, determined by the whole set of economic factors, shows the level of balance of assets and liabilities of the enterprise, as well as the effectiveness of their use. The financial condition of an enterprise is manifested in its solvency, optimality of the structure of the sources of capital and the optimality of the structure of the assets of the enterprise, primarily from the ratio of fixed and circulating assets, and also from the balance of assets and liabilities of the enterprise, its financial stability is largely enviable. Consequently, solvency, liquidity, financial stability and, in general, the financial condition of an enterprise characterize its reliability as a business partner in the conditions of renewal and development of a market economy.

Abstract
In the modern world the credit institutions importance has gone beyond monetary and credit relations. They act as institutions on a par with the state and the market. It is impossible to imagine a rational organization of economic activity on a national scale without banks. Systemically important banks can be turned into a market element, an instrument of effective state policy, with effective and productive use. Weak credit institutions act as a factor of economic degradation. Therefore, the banking system, by accumulating and distributing cash, plays an important role in the economy of any country. Crisis phenomens and the unfavorable macroeconomic situation have a negative impact on the country's economy. Instruments, that support and stimulate the banking system, is played an important role. In this case, it is necessary to take into account the individual characteristics of a particular country, applying this or that mechanism of anti-crisis regulation. In the article, based on official statistical data published by the Russian Bank and the Bundesbank, the analysis of the banking systems state in Russia and Germany was made on the basis of an assessment of key indicators of banking activity in 2007–2016, including: the assets of credit institutions, the own funds of credit institutions, and the volume of loans issued. As a result of the analysis of the Russian and German national banking systems state in conditions of economic instability, it was revealed that the measures applied by the governments of countries are only half measures, which do not give sufficient effect. Besides that the state of the banking systems of the two countries is quite unstable. However the governments of Russia and Germany are struggling with the negative crisis phenomena (currency instability, decline in investment flow, etc.) and continue improving the current anti-crisis policy and developing new measures for support the banking system.

Abstract
In the presented material an attempt to draw an analogy between the phenomenon, rather new to the Russian economy, – outsourcing and already proved – the public-private partnership (PPP) is made. The second which combines interests of the state and private business has already proved as the mechanism allowing to influence positively the Russian economy. The tendencies planned in modern economy it is characterized by gradual understanding that withdrawal by the companies from classical policy to outsourcing introduction (a conclusion of non basic assets from structure of the company and transfer of function on their management to other organizations) creates him competitive advantages. Functions, possible for transfer on outsourcing, in particular, in construction branch and housing and communal services are considered. His advantages are given, shortcomings and problems of introduction are noted. In case of the relations of outsourcing between the state and the private partner (outsourcer) of PPP it is possible to consider as his version. On the other hand, outsourcing in itself represents a form of PPP. As a result it is possible to count on advantages as one, and another. Use of PPP in the form of outsourcing gives an opportunity to effectively use the budgetary resources and to increase quality of the provided state services. Now, the minimum legislative basis for creation of the outsourcing relations between the state and the private partner is created, they are already used in the Russian economy, examples are given. Thus, outsourcing acts in two forms: as special case and as form of PPP.

Abstract
The problem of selling agricultural products has always been acute for agrarians, it is at the regional level that commodity producers are disunited and sell their products, often without knowing the state of market prices. The lack of interconnection between agricultural producers, processing industry and trade; Price pressure exerted on agrarians by intermediaries and speculators; Low competitiveness of domestic products, due to the lack of proper methods of storage, modification, sorting; Unsustainable sale of most small agricultural producers all this makes it important to create logistics integrated distribution centers (LIRTC) of agricultural products. The lack of a systemic approach, the lack of organizational and methodological support for the formation of LIRC agricultural products, the fragmented nature of applied recommendations are the reasons for the lack of a coherent mechanism for the formation of such centers on the basis of regions. Analysis of the semantics of the term “distribution center” is carried out, on the basis of the analysis carried out, the existing definition of the “distribution center” is added. The author's definition of the term “logistic integrated distribution center” of agricultural products is formulated. On the basis of the analysis of the existing classifications of the "distribution center", a set of classification characteristics was outlined, systematized and supplemented.

Abstract
In work the algorithm of creation of network model for the set complex of works is considered. The given model is under construction at the same time on the basis of two methods independent from each other: method of a critical way, method of an assessment and revision of plans. Application of these methods has allowed to solve at once two problems – to reduce duration of feasibility of working operations on critical and all full ways, and also to maintain quality of products at the standard level. On the example of the real project on the organization of production of tail plumage of the plane, consisting of the difficult interconnected operations, the model directed to reduction not only the general duration of the project, but also an early and late date of completion of events is created. Network modeling of a complex of works on preparation of production of release of a new product has allowed to plan the planned schedule of performance of a complex of the forthcoming works for the minimum period; to demonstrate those reserves of time on each constructed way which are capable to mobilize most effectively not only material resources, but also human. Possible deviations at realization of a complex of works on all possible ways are revealed that will reduce risk of failure to meet time constraints of feasibility of the project. Having constructed a consecutive logical chain of all operations of production, and, thereby, having used the differentiated approach at distribution of responsibility between all participants (separately on each separate operation), it was succeeded to affect essentially management efficiency in general on the project. Network modeling as one of methods of the analysis of early and late terms of the beginning and completion of operations on a complex of works has allowed to present visually an algorithm of realization of each stage and each operation in time, having received the expected duration of implementation of the project in end.

Abstract
The following article is dedicated to the problem of unequal access of people living in different regions. The most important social benefits financed from the regional budgets, identify the causes and possible ways to reduce inequality. The relevance of the research is determined by the purpose of creation of innovative economy in Russia and the need to improve the quality of human capital. The stated purpose requires the growth of social expenditures and changes in their structure. In this article we have analyzed the structure and dynamics of the volume of expenses of consolidated regional budgets for health, education, housing and utilities, and the social policy, as well as the costs of state social extra budgetary funds from the 2013 to 2016 years. The object of research were chosen the subjects of the Ural Federal District. Formulated conclusions are about the social orientation of fiscal policy in the regions and the most important principle of social policy is the principle of social justice. In order to reduce the structural imbalances in social spending all over the country, it is proposed to activate the mechanisms of public-private partnership, to amplify the level of control over the expense of public funds, to provide the magnification of financial sustainability of state, extra-budgetary social funds and, above all, of the Pension Fund of the Russian Federation

Abstract
Providing economic security for the development of regions, increasing their competitiveness, risk-free and sustainable activities are the main tasks of the regional program of social and economic development, which occupies a special place in the system of instruments for public management of these processes. The program of social and economic development is a unique strategy of the region aimed at security and optimization of the spatial structure and relations between the center and the regions in order to ensure economic security and growth by maximizing the effective use of existing internal and external factors. The institutional influence of the state in order to improve the economic security of regions and enterprises occurs palliatively when the business of the region is supported in direct – subsidies, and more often indirectly – compliance with the laws and regulations of the Russian Federation and the region, on the principles of institutional and market synergies. Adaptation of enterprises in the region to the market is difficult, when specific socio-organizational, economic, technical and technological, scientific, information activities in their interrelations function in the field of Russian laws. The search for ways to improve the economic security of the Russian Federation, regions and enterprises takes place in the context of global integration through the improvement of the mechanism of state regulation. An important task of the current stage of economic security of the country and regions is the construction of a system of its institutional organization that would be able to balance the levers of government with the opportunities of private enterprises, provide a quality level of providing the business with protection from terrorism, predation, financial risks, legal competition etc.
