Modeling and optimization of a multiphase sequential technological process

Abstract

In the conditions of competition and instability production companies forced continuously improve the production process and develop new innovative technologies and equipment in order to maintain their positions in the market. An important role in this play by improving the methods of planning and managing the process of production development, development of innovative products and forecasting measures to adapt to changing requirements of the external and internal market. This paper consider a multiphase sequential technological process (STP) with a branched structure at each phase of the production process. For the Poisson flow of receipt and processing of parts, a mathematical model proposed in the form of multi–channel QS with waiting and queue restriction. On this model, the criteria for evaluating the work of the STP formed and cost models synthesized for solving the problems of innovation and optimization of the STP. For each phase of the production process, the problem of evaluating the effectiveness of innovative equipment upgrades and the problem of selecting the optimal amount of equipment has solved. If there is a discrepancy between the flow of receipt and processing of parts of this mathematical model, the values of the initial criteria determined by the results of a certain number of repeated simulation of the STP operation.
