Description
The work is done in scientific and practical directions for minimization of power losses in transmission of electricity to local distribution networks between the actors of the energy (producers and consumers) of energysaving technologies focused on technological activities such as modernization and reconstruction of networks. Quite often in various circuits of power systems, it is advisable to transfer energy and its power through intermediate (transit) nodes. Structural changes in the electricity sector, at present, are mainly associated with the introduction of market relations between the subjects of energy exchange; therefore, in this work special attention is paid to the problem of calculating the power losses, as it is nonlinearly dependent on the power at the nodes and branches of a network. It should be noted that the nodes in problems transit capacity could be both sources and consumers. The latter necessitated the need for search of possible ways to reduce transportation losses of energy due to both the improvement and optimization of distribution networks and through the use of intermediate transit nodes. It follows that the transportation problem in this formulation is more General and expands the possibilities of optimization of power losses for the local subsystems of the energy clusters. The work is composed of the transport matrix for solving problems transit capacity, where the algorithm taking into account the distinctive features of which consist in the use of continuous numbering of sources and consumers in the matrix, and any node can be a transit country. The transit capacity iith node Zii=0, and the dimension of the matrix in contrast to the previously considered tasks has (n+m) (n+m) and it remains square as all the transport problems of linear programming. Transit variables Xii are included in the solution of the problem with a minus sign, and all transit variables are considered basic. From the above example in the work of a number of branches of a network is minimal, which significantly reduces the cost of building and maintaining the network, and the solver minimizes the power loss between the subjects of energy exchange and, as a result to savings from the standpoint of cost of construction of the network and the management of overflows of energy in it

05.13.10 Management in social and economic systems
DescriptionThe article considers the most used methods and means of knowledge extraction taking into account the quality assessment of models in decision support systems. In scientific and practical terms, the possibilities of joint effective use of expert systems, data mining (IAD) and machine logical inference (MLV), which provides deeper data processing, taking into account the significant differences between databases (DB) and knowledge bases (BZ). DB is a unit of information unrelated to each other information, while BZ – not only related to each other, but also with the concepts of the world, which makes it possible to solve complex multicriteria problems in various subject areas. Currently, increasing attention is paid to nonnetwork technologies that have the ability to simulate nonlinear processes, work with noisy data, as well as the ability to learn and selfstudy, extracting essential features from the incoming information. At the same time, the integration of neural network technologies and artificial intelligence models into a single hybrid system together with the methods of logical inference in the form of a hierarchical sequence of the "Ifthen" rules structure significantly improves the understanding of the studied process and the quality of presentation of the result. Nevertheless, these methods and means of knowledge extraction are insufficient if the fuzzy linguistic inference mechanism is not used. The basic characteristic of fuzzy sets is the membership function, which is a generalized characteristic of a normal set. To set this feature, we use three types of shapes – triangular, trapezoidal and Gaussian type and two main procedures – phasefication and dephaseification which is considered by the example of the method of Mamdani. Along with the stated most promising direction in this area is the adaptive gain algorithm called AdaBoost, where the limitation of the gain due to the filtering is to apply the subsampling circuit which has the normal contour of batch training, reusable training data. This provides an opportunity to work with weak models, and in the conditions of hybridization causes efficiency increase, strengthens the classifiers united in the "Committee". Each next set of classifiers is built on objects incorrectly classified by previous sets. AdaBoost is sensitive to data noise and emissions and is less susceptible to retraining, which can significantly reduce the number of examples and obtain better output in the DSS

Description
The development of agroindustrial integration is an objective economic process involving, on the one hand, with the social division of labor and specialization, on the other  with the necessity of interaction between specialized sectors and modes of agricultural production. Agrarian enterprises come into this unification movement, seeking to reduce the risk, the occurrence of which is associated with the production depends on climatic conditions, natural agricultural products market, the dictates of the processing enterprises, the need to improve the competitiveness of production. Processing and service companies are also seeking to secure a stable income thanks to the raw material base, better use of raw materials, improving the quality of its products, decreasing the price and conquering markets. In most cases, the object is to integrate agriculture, and direct or indirect initiators often are nonagricultural plants and firms that concentrate the bulk of production and sales of AIC final product. As a result, the concentration of production results in savings on its scale, socalled technicaltechnological economy. Increased production expands beyond the optimal use of machinery and equipment. The more spread out are agricultural producers, so it is more difficult to realize their interests for scaling up. In the Russian practice we have developed a variety of organizational forms of integration differ in the nature of economic relations between the parties, the degree of independence of members of the business combination, the combination of centralization and decentralization. Conventionally, they are divided into associative  "soft" and corporate  "hard". By "soft" forms of association include associations, unions, nonprofit partnership and a strategic alliance. They can function effectively at the interregional level. Hard type of integration ties characteristic of plants, corporations, trusts, holding companies. Agricultural credit consumer cooperatives (ACCC) is a voluntary association of individuals and legal entities residing or conducting their business activities in certain rural areas, on the basis of membership and monetary union shares in order to meet the needs of the members in the credit and other banking services

ANALYSIS OF CONDITIONS OF FORMING EFFECTIVE ASSOCIATIONS OF DAIRY SUBCOMPLEX ENTERPRISES OF AIC
DescriptionThe authors investigate the conditions conducive to the formation of effective associations of raw material enterprises of the agroindustrial complex and raw material processors. The unbalanced process of relations between agricultural producers and processing plants negatively affects the economic position of the partners of the merger. The diktat of low purchasing prices for raw materials by processing enterprises hinders the costeffective operation of agricultural commodity producers. Procurement prices set by dairy processing enterprises for milk do not compensate not only production costs, but also losses from inflation. This leads to a sharp decline in the profitability of milk production. A paradoxical situation arose: on the one hand dairy plants encountered an acute shortage of raw materials, on the other, the problem of selling milk by its producers at an acceptable price was aggravated. The disparity between the purchase prices for milk and retail prices for dairy products has led agricultural enterprises to explore alternative markets. On the basis of the mathematical model of the agricultural consumer cooperative, conditions for the formation of effective associations of enterprises of the dairy subcomplex of the agroindustrial complex are analyzed

01.00.00 Physicalmathematical sciences
DescriptionIn this article, we discuss various issues related to the formulas approximating the distribution function of prime numbers pi(x). This question has occupied many scholars, but the exact function is well approximated function pi(x) over the number of positive integers not. Based on certain hypotheses, we present a new function s(x) is very well approximated pi(x). The above article hypotheses are so important that their numerical validation and refinement for the lengths of the segments more in 1014  one of the main areas related to the problem of approximation of the function pi(x) throughout the series of natural numbers. After analyzing the behaviors and constructs many functions, we are building the basis of the function s(x), which is well approximates the function pi(x) throughout the series of natural numbers. We also present a table of values for x, less or equal 1022 for the difference of s(x)  pi(x)

Description
The work is done in a scientific and practical ways to minimize power losses in the transmission of electricity in the interregional distribution networks from the sources to the consumer by the use of tasks, ensuring the gradual improvement in the support program, not only from the standpoint of the efficiency of reduction of transported power loss, but also due to a significant decrease the complexity of the calculations. The resulting shortage of electricity power associated with its transfer to the electricity networks, has demanded the need to find possible ways of reducing the value of electricity losses during transportation, both by improving and by optimizing distribution networks schemes. Consolidation into a single set of electrical equipment, called the power cluster is connected to the sources of power and energy consumption, make better use of new principles of control technology and the transmission of electricity, on the basis of an automated monitoring system, ensuring the redistribution of energy flows and optimize them. The process of electric power transmission and reduction in electric power loss can be considered on the basis of linear programming problems, and their modification in the form of a transportation problem, and as a result, the transport matrix. On this basis, manipulating the data table, we can find acceptable solutions, well and then determine the best of them. As examples, this work has carried out the study on the basis of the three methods  "northwest corner", the method of minimum unit cost of electricity transport, as well as the method of the potential. The use of these three methods yielded acceptable solutions, to identify the most appropriate for the number of steps carried out at the decision, to reveal that the winner is the potential cost method
