A MATHEMATICAL MODEL OF OPTIMIZATION OF THE VOLUME OF MATERIAL FLOWS IN GRAIN PROCESSING INTEGRATED PRODUCTION SYSTEMS

abstract 1001406017 issue 100 pp. 315 – 337 30.06.2014 ru 852
The article suggests a mathematical model of optimization of the volume of material flows: the model for the ideal conditions; the model for the working conditions; generalized model of determining the optimal input parameters. These models optimize such parameters of inventory management in technology-integrated grain production systems, as the number of cycles supply, the volume of the source material and financial flows. The study was carried out on the example of the integrated system of production, processing and sales of wheat (bread) with the full technological cycle

ADAPTATION OF THE MODEL OF BINARY DECISION MATRIX TO THE PROBLEM OF THE CHOICE THE TECHNOLOGY OF CULTIVATION CROPS

abstract 1141510115 issue 114 pp. 1595 – 1606 30.12.2015 ru 381
Grain is of strategic importance and is the basis for food security. The gross national product share of grain and its products is about 10-15%. It always stands out from other types of raw materials, as it is used to produce the most popular daily foods. According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of adaptation and the possibility of using the model and the method of binary matrices to solve the problem of the choice for cropping technology

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

abstract 1231609096 issue 123 pp. 1392 – 1422 30.11.2016 ru 79
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

ANALYSIS OF EXISTING HYPOTHESES OF MECHANISMS OF INFLUENCES OF ACOUSTIC AND MAGNETIC FIELDS ON TREATED LIQUID

abstract 1301706017 issue 130 pp. 253 – 267 30.06.2017 ru 55
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device

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 110
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)
