PERFORMANCE MODELS FOR SMALL PROCESSING COMPANIES OF AGRARIAN AND INDUSTRIAL COMPLEX (part 2)

abstract 1321708120 issue 132 pp. 1443 – 1464 31.10.2017 ru 86
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

PHYSICAL MEANING OF CERTAIN SIMILARITY CRITERIAS OF TRANSPORT PROCESSES IN THE DESALTING CHANNEL THE ELECTRODIALYSIS DEVICE WITH ELECTROCONVECTION

abstract 1051501051 issue 105 pp. 845 – 864 30.01.2015 ru 805
The phenomenon of electro convection in membrane systems is of considerable interest, because it is, according to many authors, the main mechanism of overlimiting mass transfer. A great number of theoretical and experimental works, in which, as a rule, dimensional values were used, are devoted to electro convection study. Because of that, in actual fact, there is investigated the influence of individual factors on the transfer process. For example, the influence of voltage jumps, the average speed of a forced stream of the solution, the geometric characteristics of the channel, the initial concentration, etc. However, the influence of these factors appears not separately, at the same time. Thus, there is the problem of introducing dimensionless complexes of dimensional values that have a physical meaning and that allow to evaluate the inner links of the process. As it is known, for solving that problem, there is applied a theory of similarity, based on the transition towards dimensionless parameters in equations and formulas describing the process, and using values, typical of the system under study. This work is devoted to the determining of physical meaning of similarity criteria of salt ions processes, taking into account electro convection in the desalting channel of electro dialysis apparatus. The channel is bounded with perfectly selective, homogeneous anion-exchange and cation-exchange membranes. The introduced similarity criteria are used so as to conduct the theoretical study of the effect of a number of parameters of a desalting process on electro convection

PSEUDO-NOISE SEQUENCE ACQUISITION ALGORITHM FOR MULTI-CARRIER COMMUNICATION SYSTEMS RESEARCH USING COMPUTER MODELING

abstract 1111507110 issue 111 pp. 1677 – 1687 30.09.2015 ru 922
The goal of the study is to research experimentally a pseudo-noise sequence acquisition method for multicarrier communication systems of MC-DSCDMA, that allows low hardware requirements and able to operate in low quality channels. The way of achieving this lies in using a specially developed computer model of algorithm in Simulink. The achieved results have shown high efficiency of the considered acquisition method in contrast to sequential search method. The proposed algorithm can be used in multicarrier systems for acquisition of aperiodic pseudo-noise sequences in wireless public networks and in military communication networks

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 196
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

RESEARCH AND DEVELOPMENT MULTICRITERIAL ECONOMIC AND MATHEMATICAL MODELS COMPREHENSIVE ASSESSMENT TECHNOLOGY GROWING CROPS

abstract 1221608080 issue 122 pp. 1200 – 1215 31.10.2016 ru 219
Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product, is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortagecovered by imports.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 developing multicriteria economic-mathematical model of a comprehensive assessment of technology of cultivation of agricultural crops.
