Description
The integration of producers of raw materials and its processors into the agro-industrial complex is connected with the social division of labor, its specialization, the need for interaction between specialized branches and types of agro-industrial production. Agrarian enterprises are united in an effort to reduce the risk, the emergence of which depends on the climatic conditions, the spontaneity of the agricultural market, the dictates of processing enterprises, the need to increase the competitiveness of production. In the Russian practice, there were various organizational forms of integration, differing in the nature of economic ties between participants, the degree of independence of the enterprises entering the association, the combination of centralization and decentralization of management. Conventionally they are divided into associative - "soft" and corporate - "hard." The "soft" forms of association include as-association, union, non-profit partnership and strategic alliance. They can effectively function at the interregional level. A rigid type of integration ties is characteristic for combines, concerns, trusts, holdings. Agricultural consumer cooperatives are voluntary associations of legal entities and individuals residing or operating in a certain rural area on the basis of membership and pooling of money units in order to meet the needs of members in credit resources and other banks services. The conditions for the emergence of sustainable integrated associations in the agroindustrial complex require qualitative and quantitative analysis based on mathematical modeling

DEVELOPMENT OF AN EXPERT SYSTEM FOR DIAGNOSIS MALFUNCTIONS OF ENGINES OF DIESEL POWER STATIONS
DescriptionThe article considers development of expert system based on semantic networks for diagnosis malfunctions of the diesel power stations engines. The method allows developing expert systems via objectoriented programming language. The expert system allows to identify the problem without involving additional staff: at the start and overheats of the engine, when there is low power, with decreasing pressure etc

Description
The work is scientific and practical in nature, same as the discussed process of optimization of power losses in power networks based on the use of the transportation problem, namely the rules of the minimum element of the transport matrix, which is a valid solution. The mechanism of the improvement of the obtained feasible solutions to the tasks focuses on using the potential method, assigning each row and column of the matrix their corresponding potential. Using a basic variable and manipulating the elements of the transport matrix according to a specific algorithm, we implement the construction of a new support plan. Based on the plan and its acyclic, we build two cycles and determine the values of the estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes it easy to program all computational operations and quickly obtain the result of the optimization of power losses in the design of the electricity network, thereby reducing the economic and technological costs. As a result of joint use of transportation problems and potential method, we could find the optimal solution based on improved solutions more efficiently, and a scheme of optimal electric network. As consumers, in practice, there may be urban and agricultural, industrial enterprises, regional and district subordination, including industrial, agricultural and individual customers

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 net-works 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

ON THE NUMERATIONS OF THE FINITE PARTIALLY ORDERED SETS
01.00.00 Physical-mathematical 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)

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 cost-effective 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
