abstract 1321708120 issue 132 pp. 1443 – 1464 31.10.2017 ru 372
The article proposes a solution to one of the problems of small business, which is creation of a part of the software of management of information system efficiency for small processing enterprises of AIC. The fact is, that currently, there are almost no information systems to support small business. All known information systems have approximately the same list of automated functions, covering the accounting phase, and sometimes phase of analysis. Practically, not affected by the evaluation function of the economic situation, prediction, planning and regulation. The proposed mathematical model has been developed on the basis of the creation of streaming schemes of one-product processing enterprises of agroindustrial complex and mathematical description of the proceeding financial and material flows

ANALYSIS OF FACTORS AND INDICATORS OF THE INFLUENCE OF THE INTERNET ON THE INTELLIGENCE USING DATA MINING

abstract 1201606051 issue 120 pp. 755 – 769 30.06.2016 ru 407
In the article, we present the analysis and improvement of existing methodologies for assessing the intelligence factor, taking into account its use of the Internet on a regular basis. Today, the use of the Internet in our daily activities and tasks become practice that is more common. The Internet has become a popular and most frequently used means of obtaining information quickly and in large volume. The authors suggested the presence of the Internet and its impact on the everyday use of psychological and intellectual life of the people that can be recorded because of user IQ scores. It is suggested here also gets its development in the search for and analysis of system models, allowing determining the numerical values of the parameters. Specifically, it is proposed to use a large variety of statistical data to clarify the unknown parameters that determine the levels of human intelligence, taking into account the impact of the Internet. These statistics include information such as the number of people with higher education, the number of Internet users, the degree of the Internet penetration in society, the most typical tasks that use the Internet users, and others. For the processing and analysis of the test statistics in the work proposed to use tools data mining, ie, data mining. We have also considered the most typical approaches Data mining, applied in similar research areas. We have analyzed what specific principles and methods can best approach to solving the problems of intelligence assessment indicators. The result of the article was a number of conclusions, in particular, the feasibility of applying clustering to analyze data in the field. Also, in certain cases, we provided the use of Kohonen neural network in the vector quantization network format. Methods: analysis of scientific literature and online sources of information on the current level in the field of IQ research; modeling; Methods systematization (tabular calculations and compilation); Experiment (real human test data). Methodological bases of research: a systematic approach (considering IQ in the form of a functional multi-component dependencies), probabilistic and statistical approach (provides guidance for constructing mathematical models linking together IQ and the influence exerted on it using the Internet, and to assess the reliability of a computer program ) qualimetric approach (determines the need multicriterion diagnostic influence of factors on the level of intelligence)

SYSTEMIC COGNITIVE ANALYSIS IN THE MANAGEMENT OF THE NOMENCLATURE AND VOLUMES OF PURCHASES-SALES IN AGRICULTURAL TRADE: STATEMENT OF THE PROBLEM

abstract 1331709055 issue 133 pp. 730 – 734 30.11.2017 ru 420
The performance indicators of a trading company in physical and monetary terms is significantly affected by the types and volumes of purchased and sold products, and which she purchased suppliers and the consumers sold. However, the solution to the problem of choosing the rational range of products faces considerable cost of computational and human resources, and lack of baseline data, and in real dimensions this problem has no solution. The paper proposes such a solution is very economical in costs of different types of resources based on the application of information theory, cognitive and control theory

QUALIMETRIC ESTIMATION OF INTEGRATION OF RESEARCHERS INTO THE SCIENTIFIC COMMUNITY, BASED ON THE ANALYSIS OF CITATIONS

abstract 1181604074 issue 118 pp. 1168 – 1186 29.04.2016 ru 435
The article presents the criteria for evaluating the integration of researchers in the scientific community, based on an analysis of its citations. It is known, that one of the major components of interscientific communication (communication in the scientific community) is a citation of scientific publications (monographs, articles, etc.). According to the sociological approach, a scientist is a part of society, ie, scientific community; under scientific community we understand scientific mega environment (opposed to research groups of institutions and their structural units). Integration of a researcher to the community has many aspects: on the one hand, it is - the importance of his work to the scientific community, on the other hand, it is - the use of a scientist social mega environment for building for their personal and professional development to improve their research and improve the quality of its results (in the context of the article we will consider the second aspect). Methodological bases of the research: systematic, competence, sociological, and mega-system qualimetric approaches. Methods: modeling, methods of quality control, methods of set theory, relations and graphs. Evaluation (diagnostics) involvement of scientists in the scientific community - is more complicated metrology task than the evaluation of the significance of the results of its research activities. For the authors it is clear that a mature scientist (with a high level of research competence) should intensively use the potential of the social and the cultural science international environment (community) for their personal and professional development, to improve the efficiency of this research activities and the quality of this results. The proposed indicators can be considered as group indicator variables reflecting the level of the behavioral component of the research competence (scientist). Using social media for researcher’s potential – it is necessary, but not sufficient condition for productive research, producing goodquality scientific results. In this situation, negative prognosis is more significant: poor use of social media for researcher’s potential – is a "guarantee" for low productivity of this research activities and the low quality of this results. Only the combination of the highest levels of readiness for research (research competence) with high levels of other competences (as a whole - the social and professional competence, implying the presence of the professional skills of selforganization) can be the factors of successful research

ANALYSIS OF CONTEMPORARY FORMS OF INTEGRATION AGRICULTURAL PRODUCERS AND PROCESSING ENTERPRISES OF AIC

abstract 1231609096 issue 123 pp. 1392 – 1422 30.11.2016 ru 463
The development of agro-industrial 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 non-agricultural 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, so-called technical-technological 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, non-profit 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

THE RATIONALE FOR SELECTING THE METHOD OF FORECASTING THE DEVELOPMENT OF A DIVERSIFIED CORPORATION

abstract 1221608004 issue 122 pp. 43 – 58 31.10.2016 ru 470
Application of classical forecasting methods applied to a diversified corporation faces some certain difficulties, due to its economic nature. Unlike other businesses, diversified corporations are characterized by multidimensional arrays of data with a high degree of distortion and fragmentation of the information due to the cumulative effect of the incompleteness and distortion of accounting information from its enterprises. Under these conditions, the applied methods and tools must have high resolution and to work effectively with large databases with incomplete information, to ensure correct common comparable quantitative processing of the heterogeneous nature of the factors measured in different units. It is therefore necessary to select or develop some methods that can work with poorly formalized complex tasks. This fact substantiates the relevance of the problem of developing models, methods and tools for solving the problem of forecasting the development of diversified corporations. This article compares methods of forecasting and encourages using the ask analysis which has a good theoretical justification for the meaningful interpretation of a knowledge model based on information theory; high accuracy and independence of calculation results of the unit of measurement baseline data through the use of not the correlation matrix, as in statistical systems, and matrices of knowledge. A well-developed and available Toolkit of the ASK-analysis which is an intellectual system called "Eidos" (created by E. V. Lutsenko, 1994) allows, on the basis of fragmented, noisy source data of various nature (numeric, text) to create models of large dimension. The ASK-analysis and the system of "Eidos" have been widely and successfully used in economics, engineering, agriculture, sociology and other fields. These features of the ASK-analysis have led to the fact that it was chosen as the method of forecasting of dynamics of indicators of the corporation

The article presents results of the study to assess the effectiveness of credit funds in interacting agricultural (AES) and processing (PP) agricultural enterprises. The conducted studies are a continuation of the scientific work on the development of mathematical models of interaction of the enterprises of the AES and PP, are shown in the articles [1, 2, 3]. This article presents the authors’ developed set of models of management of credit funds of interacting enterprises of an agroindustrial complex. It includes mathematical models of economic efficiency of agricultural enterprises considering the use of loan funds, as well as the assessment of the maximum amount of interest rate of the loan and the minimum selling prices of units of finished agricultural products; a mathematical model of the economic efficiency of the processing plant taking into account credit obligations of the agricultural enterprise and a model for the calculation of the minimum selling prices of its finished products; a mathematical model of the economic efficiency of the combined entity with all its loans. We have proposed a model to calculate the minimum selling prices of its finished products
