Description
The approach to the solution of resource allocation problem in the process of activity planning for research and development organization having sufficient scientific and design capacity is considered. This approach enables to solve complex resource allocation problem in the context of designing division of work and network team building and project implementation technology, using software intended for solution of traditional linear programming tasks. Database modeling technique with account of specific characteristics of this approach is described

PROBLEM OF INCREASING THE INFORMATION SYSTEMS EFFECTIVENESS IN CONTEMPORARY CONDITIONS
DescriptionThe increase of conceptual system for the description of the efficiency improvement problem has been submitted for consideration. The composition and structure individual criteria and requirements for variant formalization of complex criterion information systems effectiveness as a technical system and means of analysis and information processing have been presented as the methodological initiative in this article

AGRO-INDUSTRIAL HOLDING INITIAL DATA AND THE PROGRAM INTERFACE OF DATA STANDARDIZATION
DescriptionIn this article the initial data for construction of two-level semantic information model of agro-industrial holding management is analyzed, the problem of their automated transformation to a state which is directly perceived by the AIDOS system by means of one of its standard interfaces is raised and solved. The algorithm and a source text of the program ensuring these functions, and also the results of its work and automatically generated directories of classes and factors by the AIDOS system on their basis, and also training sample for the particular models forming a part of the two-level semantic information model of agro-industrial holding management are resulted

Description
The essence of perspective method of Direct-costing" consists of use of direct variable expenses which directly concern on production cost price (so-called relevant expenses), not only for the account, but first of all as factors of management of volumes of manufacture of various kinds of production. However this method has a number of lacks: first, this analysis is carried out within the limits of system of controlling of the enterprise, instead of branches and diversified agrarian and industrial complex of region; secondly, in calculations of this method is accepted, that production volumes linearly depend on expenses for its manufacture that is true only at extensive evolution of manufacture, in the narrow limits defined enough at which manufacture volumes can increase extensively without technology and organization change; thirdly, in calculations of this method the force and direction of influence of factors, and also a kind of function of this influence is not defined. Overcoming of these lacks could raise efficiency of the Direct-costing method and expand area of its application. However, this problem was not set and was not solved, first of all, because of absence of a corresponding mathematical method, and also program toolkit realizing it and a technique of its application. In this work the given problem is set and its complex decision is offered. Numerical examples are resulted

THEORY AND CONSTANTS OF WALL TURBULENCE
01.00.00 Physical-mathematical sciences
DescriptionThe completely closed model of wall turbulence was derived directly from the Navier-Stokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and non-isothermal turbulent boundary layer flows. The estimated mean velocity, temperature and impurity concentration profiles as well as the spectral characteristics of the streamwise velocity component are to be shown in a good agreement with the experimental data

TURBULENCE THEORY AND ROUGHNESS DENSITY EFFECT MODEL
01.00.00 Physical-mathematical sciences
DescriptionThe model of the turbulent boundary layer over a rough surface is presented. The model is based on the special type of transformation of the Navier-Stokes equation. The turbulent boundary layer in this model is considered as a flow above the rough surface gener-ated by the viscous sublayer (the dynamic roughness effect). The roughness density effect on the shift of the mean velocity logarithmic profile has been estimated in the case of 2D and 3D roughness elements

SYSTEMIC COGNITIVE APPROACH TO AGRO-INDUSTRIAL HOLDING MANAGEMENT
DescriptionIn the article the management problem of agro-industrial holding is formulated in a general way, which is, on the one hand, it is necessary to produce recommendations about holding management, where its adaptive model is necessary, and, on the other hand, the construction of its model is inconvenient because of high complexity and dynamism of internal logistics of the object of management, its territorially distributed and diversified character, a large quantity of the economic indicators characterizing its activity at various levels of its organization. The general method of the decision of the formulated problem by using the systemic cognitive approach is offered
