Computer Modeling of Repair Technological Systems in Design Practice

Abstract

AbstractThe paper deals with the creation of computer simulation models of technological systems for the repair production of rolling stock. The analysis of known methods of mathematical modeling is carried out. Their advantages and disadvantages are evaluated when used to solve optimization problems of design solutions. The requirements for computer models are formulated, the description of the modeling problem and its solution based on the modular principle of pattern networks are given. An elementary element of the model is the so-called Pattern, which has a set of certain properties, incoming and outgoing connections. By combining individual modules into a network, it becomes possible to create regular configurations, models of various technological equipment with continuity of algorithmic and information structure. According to the simulation experiment, a set of indicators characterizing the system performance, the use of equipment and means of delivery, and the quality of planning solutions are evaluated. The data of practical approbation of the proposed method in the design of objects of locomotive and car facilities are given. As a result of computational experiments, the calculated confirmation of the effect of the volume of work in progress on the performance of the technological system was obtained; the fact of the nonlinear dependence of the increase in the production capacity of the enterprise on the increase in the productivity of the main equipment was confirmed.KeywordsRepair of rolling stockTechnological designMathematical modelingSimulation modelPattern networks
