本科论文ABSTRACTFirstly, it analyzes the production management system of S company, and also analyzes the production structure of S company. It is concluded that the main problem of S company in production is low production efficiency, and its original production organization model is not applicable. In the current multi-variety and small-batch market, at the same time, the unreasonable layout of the workshop has led to higher logistics costs in the production process. Based on the above analysis, using group technology, the classification of parts, the selection and optimization of group processing technology and the design of group processing units have been improved, and the layout design of the workshop has been improved based on SLP theory.Using group technology, the characteristics of the parts of S's workshop are analyzed and classified. The production process analysis method, sequence branching method and cluster analysis method are used to divide the parts into five parts groups, and the composite process route method is used to optimize the processing technology of each group to form a group processing technology. Based on the optimization of the group process, according to the needs of each group of products, determine the working load of the computer bed equipment, thereby determining the type and number of equipment required for each group, and designing the group processing unit according to the principle. Use SLP theory to improve workshop layout. Based on the analysis of the logistics and non-logistics relationship of each operation unit, the reasonable relative position relationship of each operation unit is obtained, and the improved workshop layout is determined.Using group technology an...
