TO THE QUESTION OF FINDING THE OPTIMAL POWER LOSS ELECTRIC POWER NETWORKS BASED UPON SOLUTIONS OF TRANSPORT PROBLEMS BY THE POTENTIAL METHOD

abstract 1201606059 issue 120 pp. 870 – 887 30.06.2016 ru 481
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

LINEAR PROGRAMMING PROBLEM DESCRIBING THE MINIMIZATION OF POWER LOSSES IN TRANSMISSION OF ELECTRICITY FROM SOURCES TO CONSUMERS

abstract 1241610027 issue 124 pp. 472 – 483 30.12.2016 ru 528
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

OBSTACLES TO THE ESTABLISHMENT OF EFFECTIVE ASSOCIATIONS OF THE ENTERPRISES OF A DAIRY SUBCOMPLEX

abstract 1231609097 issue 123 pp. 1423 – 1444 30.11.2016 ru 533
The article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system

TO THE QUESTION OF THE SYSTEMATIC APPROACH TO QUALITY OF EDUCATIONAL PROCESS IN THE SYSTEM OF INDIRECT DOCUMENT FLOW

abstract 1181604077 issue 118 pp. 1213 – 1222 29.04.2016 ru 574
The article considers questions of workflow in the educational organization. It revealed the need to process everyday documents, which exchange does not have the character of strict accountability, but they are also crucial to the implementation of the work in the educational organization. The exchange of such documents is different from the traditional workflow, primarily, it is the speed of document creation and sharing them. We identified other requirements and limitations to the daily workflow of documents. The study proposed to divide document on direct and indirect. The article formulates basic differences between direct and indirect document. It also analyzes the advantages and disadvantages of traditional approaches based on file servers and cloud data storage. We list problems of implementation of the account running errands. We have offered the structure of the order in the approach. The study shows an approach to increase the quality of the educational process based on the implementation of the indirect workflow through the use of centralized WEB system for the exchange of files, documents, accounting running errands, organizing indirect document. The proposed approach takes responsibility for storage of files from the technical support department of educational organizations can work with the system with mobile and desktop devices

MATHEMATICAL MODELING OF THE RELATIONS OF PARTNERS IN MODERN FORMS OF INTEGRATION OF AGRICULTURAL MANUFACTURERS AND PROCESSING-FORMING ENTERPRISES

abstract 1301706083 issue 130 pp. 1137 – 1159 30.06.2017 ru 606
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

IMPROVING THE QUALITY OF EDUCATIONAL PROCESS THROUGH THE IMPLEMENTATION OF "SOCIAL NETWORK OF EDUCATION" SYSTEM

abstract 1181604076 issue 118 pp. 1202 – 1212 29.04.2016 ru 652
The article considers problems of the exchange of information between teachers, students and departments of educational institutions. It analyzes the advantages and disadvantages of traditional approaches: email, chat via phone, social networks. The questions of placement of information to large numbers of users were revealed. We also revealed the need to address issues related to the publication of major events, administrative announcements of educational institutions, which are visible to all users, and are assigned to a specific date. We suggested an approach to the publication of the activities of the individual system modules. The article shows a mechanism of mass mailings, providing users the ability to transmit information to two or more recipients and to ensure the exchange of information that is available only to send the recipient, as opposed to the "wall". We found an approach to increase the quality of the educational process, allowing rapid exchange of information between staff, students and departments of educational organization on the example of the system "Social network educational organization." In the approach, it has been proposed to take the ideology of social networking and project it on the specifics and needs of educational institutions, which will allow rapid exchange between staff, students and divisions (departments) educational organization. The study analyzed data on the age of users of the system over a period of 30 days

SITUATIONAL APPROACH AS AN ACTIVITY OF A SUBJECT OF MEDIATION PROCEDURES IN CRIMINAL PROCEEDINGS

abstract 1221608038 issue 122 pp. 520 – 536 31.10.2016 ru 775
This article is devoted to the situational approach to the crime aspect of goal-setting activities of a mediator in criminal proceedings. It discusses the mechanisms of reconciliation of the parties in criminal proceedings in the framework of a mediation procedure or application of mediation procedures of the parties of the criminal proceeding under applicable criminal procedure of law. Mediation is considered in the context of situational modeling and creating a system of activities of parties to the proceedings depending on mediablity or remediability of the situation. We analyze current criminal procedural legislation in the sphere of reconciliation on criminal cases of private and private-public prosecution. We have suggested considering a new direction for tactical activities of participants in the proceedings and tactical aspects in the framework of the procedural powers to reconcile the parties, and situational modeling in the framework of its application in the mediation process. In addition, there was given legal and scientific analysis of the possible tactical aspects of the use of mediation procedures in criminal proceedings. A new direction in the tactical aspect of the activities of all participants in criminal proceedings has been presented, which is a tactic of the application of mediation procedures. The process of potential reconciliation of the parties is considered in the context of the situational approach, and the activity of neurotransmitters, through case studies, depending on the possibility of reconciliation between the victim and the suspect. We have proposed a new scientific classification of situations, depending on the possibility or impossibility of the use of mediation procedures

abstract 1181604047 issue 118 pp. 805 – 816 29.04.2016 ru 899
In 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)
