Abstract

The article is devoted to the problem of improving the efficiency and quality of transport systems in mechanical assembly shops of machine-building enterprises. Imperfect organization of material flows prolongs the production cycle; equipment and personnel downtime occurs; fuel and transport maintenance costs increase. The aim of the work is to study the efficiency and quality of the transport system of a mechanical assembly shop based on the development and implementation of a methodology for optimizing material flows. A review of scientific literature on intraservice logistics was conducted. The application of graph theory for route modeling was considered. Methods of simulation modeling of transport systems were analyzed. The principles of lean production in workshop logistics were studied. The efficiency of various types of industrial transport was investigated. The absence of a comprehensive methodology combining flow analysis, space planning, and dynamic modeling was established. The work substantiates the use of information technologies in the design of serial production. The main tasks of the workshop's transport system are described. Four stages of production system design have been identified. A methodology for selecting the optimal equipment layout based on graph theory has been proposed. The optimization criterion is the minimum cargo flow capacity. The initial data consisted of the nomenclature of parts, technological routes, and cargo flow values. Graphs of material connections between equipment units were constructed. Layout matrices for two-row configurations were created. Rules for calculating cargo flow energy were developed. The methodology is advisable to use when designing flexible automated sections. It is suitable for restructuring existing production. Rearranging equipment when changing the nomenclature provides planning flexibility. The research results are of practical importance for increasing the competitiveness of machine- building enterprises.
