IMPROVEMENT OF A MULTILEVEL SYSTEM OF TRANSPORT LINKS OF FOREST ENTERPRISES AT THE REGIONAL LEVEL
DescriptionThis article considers the structure of the regional transport system of the forest complex, in which each mode of transport is characterized by a certain structure, technology of functioning and means. To describe the relationship between the parameters that determine the activity of a particular mode of transport, the production function method is used. Analytical dependence expressing the formal relationship between the parameters of various modes of transport is presented, the objective function of the organizational structure of the regional transport system management is presented, reflecting the efficiency of the entire transport system as a whole. The formulation of the problem is considered from the standpoint of game theory, in which there are four players with disparate interests: the organizational structure of the regional transport system and the three transport subsystems, each of the participants has its own control vector that belongs to the given set. We consider the case of full awareness, in which the hierarchical structure and all the objective functions of the system are known to the participants. The resulting statement of the problem is modeled by the game of four persons with conflicting interests. The game is viewed from the perspective of transport subsystems. To describe the relationship between the parameters that determine the activity of a particular mode of transport, the production function method is used. An algorithm for solving the problem is given

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

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
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

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
