INTEGRATED PRODUCTION SYSTEMS OF AGRO-INDUSTRIAL COMPLEX

abstract 1131509073 issue 113 pp. 1002 – 1013 30.11.2015 ru 975
This article is devoted to consideration of questions of agro-industrial integration. Agro-industrial complex is a difficult dynamic system, including different branches of a national economy. In this work, the scheme of agro-enterprise functioning is submitted. The scheme was constructed with use of so-called “black box” model. The agro-enterprise significantly differs from the enterprises of other branches by a number of signs of. It is connected with the fact that agricultural production is characterized by high degree of uncertainty. Tasks of the uncertainty analysis, and, as a result, different risks of the agroenterprises are actual. Development of the effective mechanism of risk management is also an important task. In this article, the features of risk classification in agroindustrial complex, including the specific risks, are considered. The agroenterprises actively use integration mechanisms for decrease of possible consequences of a risk event. There are vertical and horizontal integration. Structures of the integrated agro-industrial production systems, which construct taking into account vertical and horizontal communications, are considered in this article. The most effective is vertically matrix integration in which the diversification mechanism of business is considered. The feasibility of the risk assessment with due regard for integration communications is proved

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 994
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

ISSUES IN IMPLEMENTING MARKER BASED TRACKING ON MASS MOBILE DEVICES

abstract 1131509032 issue 113 pp. 430 – 444 30.11.2015 ru 1034
Tracking is a vast field of research associated with navigation, robotics, and virtual environments (virtual reality). Tracking for augmented reality requires higher level of precision, increased range of action, as well as work with a wider variety of input data. It is important that augmented reality technology requires tracking in real time, which also complicates the task. Correct visualization of objects in three-dimensional space requires six degrees of freedom tracking: three position values (x, y, z) and three angles (rotation around the respective axes) to determine the orientation. To solve this problem, different approaches and sensor types are being used. In this article, we present a brief history of the development of tracking technology and analyze the current approaches to implement the process of tracking on mass mobile devices such as smartphones and tablet computers. We also describe some issues in implementing optical marker based tracking for visualization of large scale models

MODERN MODELS AND METHODS OF DIAGNOSIS OF METHODOLOGY COMPETENT TEACHERS

abstract 1201606053 issue 120 pp. 785 – 812 30.06.2016 ru 1045
The purpose of the research is development of models and methods of diagnostics of methodical competence of a teacher. According to modern views, methodical thinking is the key competence of teachers. Modern experts consider the methodical competence of a teacher as a personal and professional quality, which is a fundamentally important factor in the success of the professional activity of teachers, as well as a subsystem of its professional competence. This is due to the fact that in today's world, a high level of knowledge of teachers of academic subjects and their possessing of learnt basics of teaching methods can not fully describe the level of professional competence of the teacher. The authors have characterized the functional components of methodical competence of the teacher, its relationship with other personalprofessional qualities (first - to the psychological and educational, research and informational competence), as well as its levels of formation. Forming a model of methodical competence of the teacher, the authors proceeded from the fact that a contemporary teacher high demands: it must be ready to conduct independent research, design-learning technologies, forecasting results of training and education of students. As a leading component of the methodical competence of the teacher is his personal experience in methodological activities and requirements of methodical competence determined goals and objectives of methodical activity, the process of the present study, the formation of patterns of methodical competence of the teacher preceded the refinement of existing models methodical activity of scientific and pedagogical staff of higher education institutions and secondary vocational education institutions. The proposed model of methodical competence of the teacher - the scientific basis of a system of monitoring of his personal and professional development, and evaluation criteria and levels of her diagnosis - targets system of vocational training and re-training of high school teachers. Innovation policy is a model of methodical competence of the teacher, and the main model of the mechanism of its formation - methodical activity (in close connection with other activities). Research methods: analysis of scientific and methodical literature and best practice methodological activities in educational institutions, modeling, methods of the theory of sets and relations, methods of quality control, methods of multivariate analysis systems. Methodological bases of research: a systematic, qualimetric, competence and process approaches. The work was performed as part of research projects "Monitoring of the research activities of educational institutions in the information society" (№ 16-03-00382) and "Modern information and educational environment" (16-36-00048) with the financial support of the Russian Humanitarian Foundation from 17.03. 2016
