Abstract
Summary .A mathematical model of the process of mixing cream- and vegetable spread was developed. In modeling the diffusion understanding of the nature of the process were used, allowing escape from the apparatus geometry. After turning on the mixer the mixing process begins. Its duration can be determined by the behavior of the tracer particles introduced into the agitated medium in a predetermined quantity through the free liquid surface within a short period of time. If tracer particles have the same density with the surrounding bulk liquid phase, then the path of movement of the particles and the fluid are identical. The degree of homogeneity of the composition can be stirred calculated by the coefficient of variation, which is identified by the local concentrations of tracer particles in the volume of stirred medium. The task of a one-dimensional particle transport in the plane layer of the mixed liquid is solved for their calculation. The calculated ratios obtained allow us to calculate the particle concentration at any point in the volume being mixed at random times. Based on the experiment effective mixing coefficients are identified and relations for their assessment, depending on the Reynolds number of the mixer in the range studied variations of process are offered. Using the time dependence of the variation coefficient characterizing the homogenity of the system being mixed, it is possible to determine the duration of mixing to obtain the product with the desired uniformity and homogeneity of the product under the definition of a predetermined duration of the mixing process. The variation coefficient %, indicating a sufficiently good uniformity of the spread composition was found for the spread №1, being mixed with a stirrer rotating at a speed of n=150 rev / min, and the dimensionless length of the process Fo =0,0935 for obtaining estimated relations. Using the proposed calculation algorithm one can estimate the homogeneity of the product at any time.

Summary. Developed a new system for producing concentrated semi-finished products in the form of pastes for the food industry. Currently, an important task of the food industry is the creation of new products with the aim of improving the structure of the range, saving scarce raw materials, as well as reduce sugar intake; development of product functionality and products with extended shelf life. The use of local non-traditional types of plant materials can contribute to solving existing problems. Fruit and vegetable pastes are a valuable food products which can be used as a semifinished product in the confectionery, bakery, food concentrates industry. Fruit and vegetable purees have a distinct structurally viscous or pseudo-plastic properties and concentration form a very viscous mass. Already in the beginning of the process of concentration, i.e. at a relatively low degree of evaporation that leads to a rapid increase in the viscosity of the concentrate mass and reduce evaporation. With increasing temperature is the burning mass, and also change its color and flavor. Therefore, for the concentration of fruit and vegetable purees, you must use equipment whose design takes into account the possible rheological and thermal problems. The analysis of literary data structures evaporators and studies, we developed a system for producing concentrated pastes of fruit and vegetable raw materials. Developed installation can increase the quality of the finished product due to the intensification of the process of concentration, to reduce material and energy resources, increase productivity.

Summary. A new design of the conical rotary- and film apparatus for carrying out the process of dripping phosphatidic emulsion of vegetable oils, which are used in the oil industry and other industries that use the evaporation of moisture from the high-heat-labile concentrates. As a result of experimental studies we achieved the following. The conical rotary film apparatus perforated inner cavity of the rotor is divided into a supply and distribution of the original product and vapor removal zone with a barrier that hosts spheroconical insert shapes with reverse bend the conical portion, the top of which is directed towards the delivery of the original product. In the area of supply and distribution of starting material the perforations of the rotor have a slit shape. In the cavity of the rotor curved blades are mounted whose generators have the form of the curve. This curve is obtained by approximation of the polyline. The nozzle for inputting of starting mate-rial having tangentially formed holes on both ends is rotatably mounted in the central part of the conical body along its axis, one end of which is placed in the interior of the perforated rotor in the feeding zone and the distribution of the starting material, and the other one is placed in the chamber for a starting material, which is connected in series with the heater and the feeding pump for starting material. Scientific novelty of the innovative design of the device is to reduce the amplitude of the oscillation of the film rotary apparatus by re-ducing friction of particles suspension on the rotor blades, causing higher dynamic loads, ensure even distribution of starting material on the inner surface of the housing, as well as reduction of energy consumption.

Abstract
Summary. The optimal parameters of milling and fractionation of flaxseeds were substantiated. It was found that the hull fraction with the highest content of lignan secoisolariciresinol diglucoside SDG was obtained when flaxseeds were grinded using a rotatory impact continuous operation mill at the rotation 1380-1640 rpm. Studies have shown that with the increasing of the rotor speed the number of unbriken seeds decreased. However, due to the fact that the shells are crushed more, they become more difficult to separate from the cotyledons. For identification and quantification of SDG the HPLC-MS method was used. It is found that the optimum separation membranes and cotyledon fraction occurs at sifting milled seeds sequentially through the sieves having meshes of 1 and 0.5 mm. The technology of industrial production of lignans-containing fraction and flour on the basis of flaxseeds processing were proposed. This technology includes milling flaxseeds at the rotation 1380-1640 rpm, with subsequent 2% silicon dioxide addition and stepwise sieving using sieves with the mesh size 2 mm. To use a fraction membranes high in lignans as raw material for biologically active additives to food it needed additional enforcement-ground to a size not more than 0.4 mm (technological features of capsulation). The developed technology allowed getting with maximum yields of lignans-containing fraction (10% yield) and flaxseed flour (80% yield).

Abstract
Summary. In the production technology of many foods microbiological processes are crucial to the economic indicators of enterprises and the quality of the products manufactured. The examples of this are the production, where the biomass is the end product. For example, the production of various strains of the yeast Saccharomyces for different branches of the food industry: baking, brewing, winemaking, as well as for the pharmaceutical industry. The development of mathematical models of microbial cells is one of the greatest challenges of microbiology. The need to search for mathematical models is dictated by the continuous development of microbiological industry, increases in the requirements for the production design, maintenance and predictions of the processes depending on the change of process parameters. However, this requires knowledge of the laws governing material and energy exchange between the culture medium and the cell and the availability of mathematical models describing them. This knowledge cannot be obtained without studying the biological processes kinetics. Kinetic regularities of microbial growth is largely determined by the selection method of the microbiological process and the type of equipment in which these processes occur. Many biological processes can be described with a simple mathematical model, but there are kinetic regularities of biological processes that can only be described by equations of more complex type. Culturing yeast kinetic models, reflecting the complexity of the biological processes occurring during the cultivation were obtained. According to the analysis of experimental data on the Saccharomyces cerevisiae yeast culturing with a batch process, a system of equations (mathematical model), giving a functional relationship of biomass growth and cells consumption of carbohydrates with their different initial values in a culture medium under conditions of oxygen deficiency without stirring is obtained.

Abstract
Summary. Nowadays purification of ethanol from the head and intermediate impurities is done with the selection of fractions of fusel alcohol and fusel oil from the distillation column and head and intermediate fractions impurities from condenser Epuration column operating accord-ing to the hydro-selection method. Due to this the fraction contains at least 13% ethyl alcohol, resulting in a reduced yield of the final product. Distillation of these fractions in the known acceleration columns requires increased consumption of heating steam for 6-8 kg / dal and increasing installation metal content. In this paper we investigate the process of distillation fraction from the condenser of Epura-tion column, fusel alcohol from the distillation column and subfusel liquid layer from the decanter, which is fed on a plate of supply of new accelerating column (AC), which operates on Epuration technology with the supply of hydro-selection water on the top plate and has in its composition concentration, boiling and stripping parts, a dephlagmator, a condenser, a boiler. Material balance equations of the column were obtained and ethyl alcohol concentration on its plates were determined by them. Having converted the material balance equations, we determined the dependences for the impurities ratio being drawn from the accelerating column with the Luther flows and ethyl alcohol fraction. Then we received the equation for determining the proportion of impurities taken from the column condenser with fraction. These calculations proved that the studied impurities are almost completely selected with this faction, ethyl alcohol content of it being 0.14% of the hourly output.

Summary. The extrapolation procedure based on the maximum likelihood method (MLM) is one of the perspective collective choice procedures. In the analysis of collective choice procedures check of manipulability and determination of the degree of manipulability is essential. The above procedure is subject to manipulation by participants of choice. Carrying out evaluation of the degree of manipulability of the extrapolation procedure based on the MLM by using the developed to the present time indexes is impossible because of inadmissibility of existing assumptions to the mechanism of the procedure. In the paper an index of resistance of preference relation in a pair of alternatives from the collective ordering is proposed as a criterion ofthe degree of manipulability of the extrapolation procedure based on the MLM. In the article it is given description and results of numerical experiments carried out to determine the possibility of manipulability of the extrapolation procedure based on the MLM by using three ways of change of expertsʹ opinions at various values of the index of resistance for pair of alternatives from the ordering the most vulnerable to possible manipulation by participants of choice. A purpose of manipulation was to swap the positions of the alternatives from this pair in the collective ordering. On the basis of the results of experiments it is determined а range for threshold value of the index of resistance for pairs of alternatives from the ordering above which it is not observed manipulability of the extrapolation procedure based on the MLM in the three considered possible ways of manipulation by participants of choice. In each individual case exact threshold value of the index of resistance for pair of alternatives depends on number of permissible orderings corresponding to the changed opinions of the participants of collective choice.

Summary. In many applied problems of control, optimization, system theory, theoretical and construction mechanics, for problems with strings and nods structures, oscillation theory, theory of elasticity and plasticity, mechanical problems connected with fracture dynamics and shock waves, the main instrument for study these problems is a theory of high order ordinary differential equations. This methodology is also applied for studying mathematical models in graph theory with different partitioning based on differential equations. Such equations are used for theoretical foundation of mathematical models but also for constructing numerical methods and computer algorithms. These models are studied with use of Green function method. In the paper first necessary theoretical information is included on Green function method for multi point boundary-value problems. The main equation is discussed, notions of multi-point boundary conditions, boundary functionals, degenerate and non-degenerate problems, fundamental matrix of solutions are introduced. In the main part the problem to study is formulated in terms of shocks and deformations in boundary conditions. After that the main results are formulated. In theorem 1 conditions for existence and uniqueness of solutions are proved. In theorem 2 conditions are proved for strict positivity and equal measureness for a pair of solutions. In theorem 3 existence and estimates are proved for the least eigenvalue, spectral properties and positivity of eigenfunctions. In theorem 4 the weighted positivity is proved for the Green function.

Summary. Control systems using a network channel for communication between the elements are called network management systems. Using networks to connect geographically distributed components of the system has a number of advantages, such as reducing the cost of system installation, compact size and weight, ease of diagnostics and system maintenance, and increased flexibility. Nevertheless, the use of networks has also created new problems that did not exist in conventional control systems. These issues should include a random time transmission over the network from one device to another network device, possible loss of data packets during transmission, an asynchronous mode of operation control system components. Network features make analysis, modeling, and management of network management systems more complex and difficult task. This complexity is due primarily to the fact that such systems require complex research, including research on the theory of communication and control theory. One of the challenges in the modeling of management systems, is a simulation of the transmission channel. In this paper we propose an approach for modeling the particular case of the transfer process. Considered a network channel with a random delay and packet loss. It is assumed that the channel can simultaneously transmit multiple data packets. Time delay is modeled random distribution law Erlang appropriate order. The probability of packet loss depends on the arrival rate of data packets in the channel transmission and the parameters of the law Erlang distribution. A model of the channel as a series connection of discrete elements. Discrete produce independent quantization of the input signal. This representation allows to model the random data. The formula for determining the probability of packet loss during transmission.

Thus, the purpose is research on the basis of system approach of complex technical providing the information management system and development of a number of methods of the analysis and the synthesis of complex technical providing suitable for use in engineering practice of design of systems. The well-known paradox of development of management information consists of that parameters of the system, and consequently, and requirements to the complex hardware, can not be strictly reasonable to development of algorithms and programs, and vice versa. The possible method of overcoming of these difficulties is prognostication of structure and parameters of complex hardware for certain management informations on the early stages of development, with subsequent clarification and working out in detail of them as far as development and clarification of other subsystems of management information, i.e. decision of questions of development of complex hardware in the conditions of incompleteness of data about the info-base of the system.

Summary. In operation of industrial pyrolysis furnaces, the main task is the selection of the optimal mode of thermal decomposition of the feedstock, depending on the yield of the desired products under conditions of technological limitations on the process. To solve this problem for an operating reactor, this paper considers the SRT-VI Large-Capacity industrial Furnace , the mathematical model of the pyrolysis process was constructed, using a kinetic scheme which consists of primary reaction of decomposition of raw materials and secondary elementary reactions of interaction of the considered mixture components, the heat balance equation and hydrodynamics of flow in the coil. The raw material for the selected installation type is naphtha (straight-run petrol). Output parameters of the model are the molar costs of marketable hydrocarbons. The reactor is described by the equation of ideal displacement in the static mode of operation. It is assumed that all reactions have a temperature dependence that follows the Arrhenius law. The activation energies of chemical processes were estimated using the PolanyiSemenov equation and identification of pre-exponential factors was carried out using a genetic algorithm (GA). This task requires solving simultaneous system of differential equations describing the pyrolysis process and a search for a large number of unknown parameters, and therefore it is proposed to modify the GA. Optimal scheme includes Gray encoding arithmetic operators, tournament selection, with tournament ranking more than 4, crossover with partial random choice of alleys, mutations with a high probability of occurring and elitism with competitive global competition. Using the proposed approach, the parametric identification of model process is accomplished. The analysis of the simulation results with the data of operating reactor showed its suitability for use in order to control the pyrolysis process.

One of the promising directions of development of network management systems is the use of common computer networks in the control loop for the exchange of information between elements of the system. Such a construction of control systems leads to new problems. So in the design and study of such systems need to combine different methods of scientific fields. First of all, it is the field of control theory and communication theory. However, not all the developer has full knowledge of these areas to the same extent. To solve engineering problems, in order to ensure the required quality of operation, developed methods of analysis and synthesis of networked control systems with data transmission over a channel with competing access methods. These techniques allow the calculation of probability-time characteristics of a stochastic process data channel with competing access methods to build transients considered control systems to calculate their qualitative characteristics, to determine the conditions of stability of network systems management and tuning parameters to optimize the digital controllers for the respective criterion. These techniques are the basis for the development of software. The proposed software system allows for the analysis and synthesis of the network through which the information data exchange. As well as to study the network system for a variety of laws regulation. Complex structure based on the principles of modularity, hierarchy and nesting modules to each other. Easy to use interface allows the software user numb special training.

Abstract
Summary. To date, artificial intelligence systems are the most common type to classify objects of different quality. The proposed modeling technology to predict the quality of flour products by using artificial neural networks allows to solve problems of analysis of the factors determining the quality of the products. Interest in artificial neural networks has grown due to the fact that they can change their behavior depending on external environment. This factor more than any other responsible for the interest that they cause. After the presentation of input signals (possibly together with the desired outputs), they self-configurable to provide the desired reaction. We developed a set of training algorithms, each with their own strengths and weaknesses. The solution to the problem of classification is one of the most important applications of neural networks, which represents a problem of attributing the sample to one of several non-intersecting sets. To solve this problem developed algorithms for synthesis of NA with the use of nonlinear activation functions, the algorithms for training the network. Training the NS involves determining the weights of layers of neurons. Training the NA occurs with the teacher, that is, the network must meet the values of both input and desired output signals, and it is according to some internal algorithm adjusts the weights of their synaptic connections. The work was built an artificial neural network, multilayer perceptron example. With the help of correlation analysis in total sample revealed that the traits are correlated at the significance level of 0.01 with grade quality bread. The classification accuracy exceeds 90%.

Summary. The concept of algorithmic models appeared from the algorithmic approach in which the simulated object, the phenomenon appears in the form of process, subject to strict rules of the algorithm, which placed the process of operation of the facility. Under the algorithmic model is the formalized description of the scenario subject specialist for the simulated process, the structure of which is comparable with the structure of the causal and temporal relationships between events of the process being modeled, together with all information necessary for its software implementation. To represent the structure of algorithmic models used algorithmic network. Normally, they were defined as loaded finite directed graph, the vertices which are mapped to operators and arcs are variables, bound by operators. The language of algorithmic networks has great features, the algorithms that it can display indifference the class of all random algorithms. In existing systems, automation modeling based on algorithmic nets, mainly used by operators working with real numbers. Although this reduces their ability, but enough for modeling a wide class of problems related to economy, environment, transport, technical processes. The task of modeling the execution of schedules and network diagrams is relevant and useful. There are many counting systems, network graphs, however, the monitoring process based analysis of gaps and terms of graphs, no analysis of prediction execution schedule or schedules. The library is designed to build similar predictive models. Specifying source data to obtain a set of projections from which to choose one and take it for a new plan.

In order to create a technology "whipped" bread for school meals, determined to investigate the influence of recipe components on the processes of structure formation. Received a few factors: the magnitude of the current drive, bulk density, test temperature and test duration of kneading, and the integral curves depending on the diameter of air bubbles. To test a variety of prescription formulations characterized by the higher values of current in the formation of its structure and decrease when it is churning. With increasing temperature of the test processes, leading to an increase of its viscosity intensifies. The presence in the formulation of Apple powder leads to a sharp increase in the viscosity of the dough due to the high water absorption capacity. The dependence of bulk density on the duration of the process of churning the dough with different prescription composition characterizes the formation of the foam structure of the test. The decrease in volume weight on the duration of the churning of the test is identical, however, as the saturation of the air test, the intensity of decrease in volume weight test for them is changing. This is due to the foaming ability of the prescription of the test and thus the formation of a foam structure with different dispersion of air bubbles. The higher foaming ability of the prescription of the test and its viscosity, the higher the dispersion of air bubbles. With the increase of dispersion of air bubbles increases the firmness of bread crumb during baking. Dispersion of air bubbles affects the stability of the crumb during baking, the specific volume and porosity of bread. Analysis of results and properties of the obtained products showed that they possess the organoleptic and physico-chemical properties and are enriched with new products.

Abstract
Summary: Bacterial cellulose is an organic material that is synthesized by microorganisms extracellularly. Bacterial cellulose can be used in various industries. Especially, bacterial cellulose has found its application basically in medicine. The production of bacterial cellulose is a complicated and long process. The principal criterion for the process to be successful is bacterial cellulose to be obtained in a higher yield. Russia is lacking an operating facility to produce bacterial cellulose; therefore, research in this art is the hottest topic. This paper reports details on the biosynthesis of bacterial cellulose by the Мedusomyces gisevii microbe and investigates the effect of active acidity level on the bacterial cellulose synthesis. It was found that the synthesis of bacterial cellulose by the symbiosis of Мedusomyces gisevii does not require pH to be artificially maintained. The substrate concentration effect on the bacterial cellulose yield was also examined. The bacterial cellulose synthesis was witnessed to be conjugated with the acetic-acid bacterium growth, and conditions corresponding to a maximal bacterial cells number correspond to a maximum microbial cellulose yield. The maximal bacterial cell number was observed when the glucose concentration in the broth was 20 g/l; as the glucose concentration was increased to 55 g/L, the acetic-acid bacterial cell number diminished in inverse proportion to the substrate concentration, which is likely due to the substrate inhibition. A glucose concentration of 15 g/l and lower is not enough, causing a decrease in the cell number, which is directly proportional to a decline in the substrate concentration. The maximum bacterial cellulose yield (8.7-9.0 %) was achieved at an initial glucose concentration of 20-25 g/l in the broth. The conditions providing the maximum bacterial cellulose yield gave an enlarged bacterial cellulose specimen 605 g in weight. The physicochemical properties of the bacterial celluloses were studied. The structure and purity of the bacterial celluloses were confirmed by infrared spectrophotometry.

Summary. Food fibres are included in the list of useful substances necessary for the normal functioning of human organism. It is part of products, that the enzymes of stomach and bowels are unable to overcook. There are they in fruit, vegetables, skin of bobs, and as early as shell of seed and cereals. In Russian Federation the valuable source of pectin is a sugar-beet bagasse, because other types of pectin-containing raw material can not compete with it on a low cost and present resources. A sugar-beet pectin possesses a high protective action, i.e. by ability to destroy poisonous substances and radionuclides from an organism. In spite of deficit of pectin in Russia, considerable home production them is presently absent. The methods of production of pectin offered before were bulky, with the low level of apparatus-technological registration and considerable expenses of reagents does not provide the favourable terms of labour with considerable ecological problems. The aim of work is perfection of the modes of receipt of pectin from a sugar-beet bagasse with using as an extractant of the electrochemically activated water. Application of such method allows to soften the process of hydrolysis-extracting, that assists not only the increase of exit and quality of pectin but also gives an opportunity of the further processing of raw material on food fibres. As a result of undertaken studies the modes of realization of process of hydrolysis-extracting of pectin are worked out from a digister. A pectin from a sugar-beet bagasse differs in high maintenance of free carboxyl groups, the use is possible as the complexing agent in a medical and preventive feed. Thus, possibility and expediency of receipt of pectin and food fibres are shown from the offered digister with using as an extractant of the electrochemically activated water. Such technology answers the requirements of ecological safety of production, carries innovative character, assists the decision of problem of the complex use of digister and market entry functional ingredients and bioactive additions of home inexpensive preparations of the complex setting.

Abstract
Summary: The investigation results of the application of pectinase and glucanase enzyme preparations for the red whortleberry raw material pretreatment during the juice production stage have been represented in this article. It has been shown that the application of enzyme preparations promotes the increasing of the juice output. The best results were obtained with the usin g of pectinase enzyme preparations. It has been experimentally verified that a larger effect can be achieved through the using of enzyme preparations with different substrate specificity in compositions. Increase of an output of juice from vegetable fabric is tightly connected to intensification of such processes as hydrolysis of cellulose and a hemicellulose. Being components of vegetable cellular walls, these polysaccharides give them durability and cause rigidness of structure. Therefore use of the enzymes splitt ing cellulose and a hemicellulose will inevitably cause their destruction, will lead to irreversible violations of integrity of a cellular wall, its destabilization and, as a result, increase in an output of juice. Besides, hydrolysis of neutral polysaccharides is followed by release of the related organic acids, phenolic substances. When corrupting cellular walls also large number of vegetable colorants that is especially important in case of manufacture of berry juice is selected.

Summary. Currently in the repair and manufacture at the stage of recovery of steel parts, widely used special coatings formed by electrolytic effects on ferrous ions. This technique offers high performance, ease of implementation, low cost of technological equipment and materials used, as well as easy automation of the process. However, this method has several disadvantages: low fatigue strength of reconditioned parts, insufficiently strong grip of the iron coating to the substrate, particularly in alloy steels, insufficient wear resistance. For the purpose of increasing durability and wear resistance of parts, restored through electrochemical action, it is proposed to use chemical-heat treatment, consisting in the application of carbonitriding. Investigated the efficacy of different modes of carbonitriding in the highly carburizing paste-and their influence on the structure and properties of iron plating. It is established that the nitrocarburizing both low and high temperatures repeatedly (6-7.5 times) increases the microhardness of the coatings. The highest hardness is obtained by low-temperature carbonitriding with direct quenching in water. Conducting the carbonitriding process at low temperatures (650 °C), significantly increases the hardness of the iron coatings, increasing the limit of its fluidity, a and also greatly increases its endurance limit. Nitrocarburized fatigue strength of samples with iron precipitation on the surface, as shown by our studies, not only higher strength of the same samples without carbonitriding (more than 2 times), but higher than the fatigue strength of the base metal without coatings. Raising the temperature of the carbonitriding did not increase the hardness of electrolytic iron. Developed a rational technology of hardening of steel parts, re-chain iron fortification. Selected optimum conditions for carbonitriding hardening restored iron fortification, with the purpose of increasing durability of machine parts Optimal process temperature re-benching of the process of carbonitriding in which is possible to obtain maximum fatigue strength and wear resistance from the restored detail, is the process of carbonitriding at 650°C, followed by quenching and tempering at 150 °C.

Abstract
Summary. Ensuring food security of Russia is one of the strategic tasks solved during sustainable social and economic development of national economy. The key role is played in this regard by processes of integration of the interfaced productions – subsystems of agro-industrial complex (agrarian and industrial complex). The modern directions of development of economic activity of the organizations of a food and agricultural profile to some extent already use integration advantages, however thus there are insufficiently balanced target interests of the interfaced participants of agro-industrial production that is directly or indirectly reflected in methods and instruments of organizational management. For mitigation of this situation and leveling of influence of factors of imbalance of management processes, it is offered to reform modern system of the business relations in agrarian and industrial complex on the basis of creation of the polycluster formations possessing the following key properties: territorial concentration of subjects; intra cluster competition; stability of economic relations; politsentrichnost; sona-pravlenny development of subjects; manifestation of a positive synergy. Considering these attributive lines of a cluster, methodological approach to creation of the agrofood polycluster formation (APF) is developed, using instruments of interindustry reengineering, in a beet sugar subsystem of agrarian and industrial complex. The aprioristic analysis and an assessment of conditions and a tendency of functioning of the interfaced participants of beet sugar production where negative consequences of the import substitution which is real threat of food security are most shown formed the basis for introduction of APF in this subsystem. As the characteristic of the content of the updated methodological approach to creation of APF the matrix of interface of target interests of subjects of a cluster in which structure are included is developed: state, cluster, sugar plants, beet-raising farms, seed-growing farms, research establishments, educational institutions, other organizations. The matrix diagonal visually shows an essence of two-uniform advantage of this type of APF: activation of processes of interface of target interests on the basis of self-development and integration of the knowledge accumulated by subjects of a cluster that in total allows to protect competitive advantages of a cluster at the intercluster level. Especially in the course of functioning of agrarian and industrial complex the assessment of pro-allowances of safety which is offered to carrying out hierarchically in the following sequence has importance: assessment of potential of ensuring industrially production safety with polycluster formation; cluster contribution assessment to achievement of industrial and production and food security.

Summary. As a result of investigation of science and methodical approaches related problems of building and development of innovation clusters there were some issues in functional assignments of innovation and production clusters. Because of those issues, article’s authors differ conceptions of innovation cluster and production cluster, as they explain notion of innovation-production cluster. The main goal of this article is to reveal existing organizational issues in cluster building and its successful development. Based on regional clusters building analysis carried out there was typical practical structure of cluster members interaction revealed. This structure also have its cons, as following: absence cluster orientation to marketing environment, lack of members’ prolonged relations’ building and development system, along with ineffective management of information, financial and material streams within cluster, narrow competence difference and responsibility zones between cluster members, lack of transparence of cluster’s action, low environment changes adaptivity, hard to use cluster members’ intellectual property, and commercialization of hi-tech products. When all those issues listed above come together, it reduces life activity of existing models of innovative cluster-building along with practical opportunity of cluster realization. Because of that, authors offer an upgraded innovative-productive cluster building model with more efficient business processes management system, which includes advanced innovative cluster structure, competence matrix and subcluster responsibility zone. Suggested model differs from other ones by using unified innovative product development control center, which also controls production and marketing realization.

Abstract
Summary. Modern global processes identified human capital, education and science as determinants of innovation development. In order to achieve economic growth the government should create the necessary conditions for effective interaction of business, scientific and educational processes at the level of each region. Most of the subjects of the Russian Federation tend to the mono-production of individual industries. The basic industry of the Lipetsk region is metallurgy. The policy of modernization and differentiation of economy allowed to reduce the share of this sector to 55% and led to the rapid development of other industries, agriculture, food and processing industry and construction. Innovations are widely supported and new types of production are created in the region. High rates of economic development have affected the regional labor market, changed the structure of labor demand and increased employers’ requirements to the quality of educational programs. The system of vocational education of the Lipetsk region is represented by the institutions of different levels. It offers a wide range of educational programs for traditional sectors of the regional economy. New and high-tech industries have a shortage of personnel. Employers demand engineering and technical professions and highly skilled workers. It is necessary to organize continuous improvement of qualification and create a system of continuous and advanced vocational education. To solve the problem of the shortage of labour in the region the Concept of "Human resource development of the Lipetsk region” was developed and approved. There is a Coordinating Council on staffing and vocational education. The road map for the creation of manufacturing and educational clusters was approved. Manufacturing and educational cluster of metallurgical profile proved to be effective. Three more manufacturing and educational clusters of machine-building, agriculture and construction profiles are created and developing. It is necessary to strengthen the integration of the business community and education, to form professional competence, to extend forms of interaction between the real sector of economy and professional educational institutions.
