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.

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

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
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
