Description
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 shortage was covered 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 a complex of mathematical models and methods for evaluating alternative technologies for agricultural production (using the example of crop production), their software implementation, and the main scientific results of the project

Description
The reasons diminishing the efficiency of those approaches or the difficulties in their realization are explained. The authors propose 2 models of rural tourism development as a tool for territorial development and, as consequence, regional economic development. The first model foresees large investments from the national and regional budget. The second one proposes the review of the economic actors’ roles in the development of regional economics and in activation of the entrepreneurship activity. In the framework of the second model the investment from the national and regional budgets to be reduced and, in part, tools of a territorial selforganization to be launched thanks to activity of special couch groups and integrating the territory in the process of digital economy

Description
In this article, on the basis of phenomenological consideration of kinetic processes in semiconductors volume, we have conducted an analysis, in order to estimate the drift and diffusion components of the output current for hot carriers in the total output of the conductivity structure of the chip. The result revealed amplitude and frequency characteristics of this component of the conductivity, illustrating a greater amount of its modulus and phase inversion near the field-strength values of Ghan effect. This can be used for designing oscillators of millimeter range of wavelengths. It is shown that the nonlinear diffusion component along with the drift is important for the output conductance of the test specimen

ENVIRONMENTAL BASICS OF HEALTH TOURISM DEVELOPMENT
DescriptionThe article shows the economic significance of rational usage of natural resources for the benefits of population. The peculiarities of the three types of tourism are expressed: ecological, natural and short. The article proposes the modernization of tourism infrastructure considering the energy efficiency of buildings, consumption of "green energy" and organic agriculture, environmentally safe recycling of municipal solid waste. Such modernization provides a condition for the development of wellness and recreation of all types. The article shows the link between tourism and the improvement of the tools for cleaner production and taxation. It gives the analysis of the characteristics of the formation and use of the tourism resource rents as part of the restructuring process of taxation

ALGORITHM FOR OBTAINING MATHEMATICAL MODELS OF ELECTROMECHANICAL DEVICES
DescriptionAn algorithm for obtaining a complex of mathematical models of electromechanical devices, which can then be formalized and implemented in software, is proposed and described. Until recently, the implementation of this algorithm was possible only with the manual derivation of all expressions, which significantly hampered the work of researchers. The appearance of such programs as Maple, Mathematica and MathCAD provided the possibility to automate the process of obtaining analytical calculations that allows calculating any modes of any types of electromechanical devices, reduces the likelihood of errors and allows you to change accepted assumptions and designations in the developed models. The choice of the MathCAD program (in comparison with Maple and Mathmatica) can be justified by the fact that MathCAD has the most convenient interface, allowing not only to perform mathematical calculations, but also to present the results in ordinary mathematical notation. The analytical results obtained in MathCAD can be immediately included in numerical models

Description
We have considered the most important direction of development of enterprises of the military-industrial complex: modernizing production capacity and technical re-equipment of these enterprises. The relevance of this issue in recent years has increased significantly due to changes in the terms of military development (economic hardship, sanctions, etc.). We have developed an economic-mathematical model of the choice between modernization and radical technical re-equipment of enterprises. The article has an analysis of this model taking into account the financial factors in this choice. The use of the developed economic-mathematical apparatus in practice allows increasing the efficiency of technological development of enterprises of the military-industrial complex

ANALYSIS OF EFFICIENCY OF PRODUCTION OF PLANT GROWING PRODUCTS OF CJSC "CENTRALNOE", KRASNODAR
DescriptionThe article gives an analysis of the efficiency indicators for the production of plant growing products using the example of the reporting of CJSC "Centralnoe". We have revealed the mathematical model for the analysis of economic efficiency of production of plant growing products. In the work there were considered the following indicators characterizing economic efficiency: labor intensity; profit from the sale of fruits; profitability; cost of 1 centner of fruit; yield; costs for the maintenance of fixed assets used in production. Various models of the dependence of indicators characterizing economic efficiency on the above indicators were considered. As a basic culture, we have selected fruits, because these cultures are the main types of products for this organization. The authors singled out a reliable and qualitative mathematical model of the relationship between profit on sales and yield, labor intensity, and self-worth. Model could be used to determine the economic efficiency of organizations engaged in agricultural activities. The relevance of the study is due because these problem is one of the most important for all organizations that produce plant growing products. The agrarian sector has certain peculiarities, therefore, when determining of the economic efficiency of a separate economic entity and the industry as a whole, it is necessary to take into account these features

Description
The article substantiates the necessity to use factors that trigger development mechanisms and describe risks at various stages of the organization's life cycle in the process of developing organizational structures for such large social and economic systems as corporate integrated structures characterized by the presence of diverse organizations in their structure. A comparative analysis of approaches to the description of the life cycle was conducted, as a result of which it was determined that L. Greiner's model is incomplete (it describes only the stages of development), and I. Adizes' model contains a blurred system of factors. To solve the problems, the model of I. Adizes was chosen as the basic approach and the characteristics of the stages of the life cycle of the organizations are selected. To formalize the factors that trigger the development mechanisms and describe the risks at various stages of the life cycle of organizations, a cognitive analysis and modeling apparatus was chosen and a corresponding methodology was developed. The implementation of the methodology is represented by the example of the first stage of the organization's life cycle ("Courtship"), which resulted in the compilation of a list of factors, their mutual influence on each other, the type of communication, and the cognitive model. Analysis of the cognitive model allowed us to determine the key factor that has the greatest impact on the transition to the next stage of development
