Description
Results of internal environment integrated production system research with the point of view of qualitative analysis and risk evaluation were casted in the article. In particular, model and method of calculation of integral index of production vertical line risk and improved data-flow model of effectiveness assessment of IPS with an account of risk constituent on the stage of creation of material flow are described. Reasonability of presentation of prognostic meaning of profit in the type of indistinct triangular number was substantiated.

QUANTITATIVE MODELS AND METHODS OF RISKS EVALUATION IN AGRO-INDUSTRIAL INTEGRATED PRODUCTION SYSTEMS
Description
Results of researches on quantitative evaluation of agro-industrial integrated production systems (IPS) risks with the regard of influence of external and internal media are described in this article. Particularly, quantitative method of calculation of integrated risk indexes of unfavorable influence of external medium on integrated production systems; model of determination of IPS effectiveness on the base of worked out models of calculation of integrated risk indexes and an equipment of slipshod great numbers theory; improved model of IPS effectiveness evaluation with the regard of risk component part on the stage of material flow creation have been described.

INTEGRATED PRODUCTION SYSTEMS OF AGRO-INDUSTRIAL COMPLEX
Description
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

Description
In this article, the general structure of technologically complete production chain of the integrated production system of agroindustrial complex was considered. Three different variants of creation of the production chains are described. The main distinctions in activity of chains consist in a source of raw materials. Any technologically full vertical chain includes three stages – production of raw materials, storage and processing, realization. Each of stages is characterized by different situations of the risk. Stages of process of functioning of a production chain were considered in this article. Also, the qualitative analysis of risk for all stages is made and the results of this analysis are considered. Results of this analysis became a basis for improvement of stream model for determination of efficiency of the technological chain taking into account a risk component. In the article, the algorithm of an assessment of efficiency of the technological chain of the integrated production system taking into account a risk component at the stage of creation of a material stream is also described

Description
Relevance of developing Internet service for searching travel companions for intercity and intracity trips substantiated in the article. The existing services that provide similar services were analyzed, their shortcomings and advantages of the basic principles of operation were identified and analyzed. Functional of own service was disclosed in comparison to existing ones. The variants to benefit drivers and passengers were offered
