In this article the size of material stream in bread-production chain with use of the theory of indistinct sets and application of risk component is predicted, the interval model of definition of efficiency is developed

The analysis and assessment of risk at the macrolevel in this context is understood as assessment of extent of influence of the external environment (macro environment) on activity of the integrated production system. In the article the model and the technique of calculation of an integrated indicator of risk of an adverse effect of the external environment of the agro-industrial integrated production system is offered. All stages of creation of the model which include representation of basic risk factors of macrolevel in the form of linguistic variables are described, each of basic risk factors is a compound linguistic variable. For obtaining total value of a basic factor the matrix scheme of aggregation of compound factors to basic level is used. The equation of model of an integrated indicator of risk of an adverse effect of the external environment on the integrated production system is presented. The principle of recognition and interpretation of result on the basis of standard fuzzy 01-classificators is shown. Also in this article the interrelation of an integrated indicator with the choice of the strategy of development for business system by definition of a condition of the external environment is shown, and depending on it the strategic scenario of development of business system is offered

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

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

The article describes the process of developing the two-level technique for assessment of the missed benefit during the landing and cultivation of perennial plantings. The technique is developed for the enterprises where the cycle of production of raw materials breaks into several periods until the first harvest. The choice problem of the most suitable grades for the landing is relevant for such enterprises. The first level of the two-level technique assumes assessment of qualitative and quantitative characteristics of grades with use of such tools as the theory of fuzzy sets and the decisions tree. The results of the first level are entrance data for the second level where there is final assessment of a grade and determination of the missed benefit rather potentially possible at the choice of the recommended grade. In the article also designated the importance of the raw materials stage for the technological chain. It is shown that, being consecutive structure, the technological chain strongly depends on the first stage – a stage of raw materials production. Minimization of the risk situations at the first stage promotes strengthening of the general risk tolerance of a technological chain

In this article the model and a calculation procedure of an integrated indicator of risk of the internal environment of the integrated production system are described. Then the steps of creation of triangular fuzzy number for expected value of profit are given. At creation of this fuzzy number the concept of an indicator of risk of the internal environment of the integrated production system was used. Further on the basis of the developed model of internal risk the interval model of efficiency of the integrated production system is developed and described. In this article the structure of a production chain of the integrated production system of agroindustrial complex was considered. In technologically complete production chain, as a rule, allocate three stages – raw materials production, storage and conversion, sale of finished goods. Each subsequent stage depends from previous stage, and at each stage various situations of risk are shown. Also the process of risk identification of the internal environment of the integrated production system was considered in this article. Process decomposition is executed, the description of subprocesses is given. For a risk assessment of the internal environment it is necessary to know quantity of production chains, and also to calculate value of risk for each production chain on the enclosed algorithm. Also in the article the principle of recognition and interpretation of results of calculation of an integrated indicator of risk of the internal environment of the agro-industrial integrated production system on the basis of Harrington's scale and standard indistinct 01 classificators is shown

Model and method of calculation of integral index of influence of external environment of integrated production system were considered and interaction of given index with choice of optimal strategy of business-system development was shown in the article. Results of approbation of worked out model and method were casted.

The problem of the optimal distribution of production tasks is one of the important problems of effective planning of processes associated with production at the enterprise. However, the classical approach to solving this problem becomes of little use when the individual stages of the production process are performed sequentially and in the case when it is necessary to take into account the structural features of the technological processes of the enterprise. Purpose of work: to develop a methodology for minimizing costs in the distribution of production tasks, taking into account the structural features of the technological processes of the enterprise. We built a multicriteria discrete optimization model for the distribution of production tasks according to the structure of production elements. One of the methods based on the proposed model is proposed, which allows to identify groups consisting of four elements in the production structure of the enterprise. The model is built using a network design which are pre-fractal graphs. The use of pre-fractal graphs allows you to naturally represent the structure of production and technological links of the elements of the production system of large enterprises. The results of the work is the developed effective methodology for solving the problem of the network distribution of production tasks, taking into account the structural features of technological processes at the enterprise, the economic effect of which is to minimize resource costs. Based on the constructed model, we can develop automated means of monitoring and managing the production processes of a company
