[Abstract]:With the deepening of reform and opening up and the development of market economy, the domestic automobile manufacturing industry is facing unprecedented competition. At the same time, the automobile parts manufacturing industry is also facing a great challenge from the foreign auto parts manufacturing industry. If domestic auto parts manufacturing enterprises want to take the lead in the fierce market competition, they need to introduce advanced manufacturing systems, implement the transformation of production mode, and accelerate the transition from extensive to lean mode. The production layout design is the premise for the enterprise to realize the transformation of production reform. Adapting to the production layout of the advanced manufacturing model can ensure the rational and effective distribution of manufacturing resources, enhance the ability of the enterprise to respond to the diversification of market demand and the sensitivity of the enterprise. On the other hand, it can effectively control the production cost, reduce the inventory, improve the production efficiency and optimize the production environment. From the point of view of automobile gearbox manufacturing enterprise, this paper studies and discusses the layout design of gearbox factory production workshop on the premise of understanding the company's demand and manufacturing technology. This paper first introduces the general situation of workshop layout design and simulation, and then introduces the concept of workshop layout, the formal principle of facility layout, the influencing factors and the theoretical method of workshop layout. This paper introduces two methods of layout theory: system layout design (SLP) and genetic intelligent algorithm. Then combined with the data collected during the preliminary investigation and preparation period, using the SLP theory, the logistics relationship analysis and non-logistics relationship analysis of the workshop layout are carried out. Considering the manufacturing process characteristics of the gearbox and the future strategic planning of the enterprise, the integrated correlation position relationship between the operation units is analyzed through the weight value, and the integrated position correlation diagram of the operation unit is drawn. Based on the qualitative analysis of SLP, a mathematical layout model with the objective function of controlling workshop logistics cost is established. Using the unique multi-line shop layout coding scheme and the partial matching crossover genetic algorithm strategy, the genetic algorithm is programmed to solve the mathematical model of the workshop layout in MATLAB software development platform, and the shop layout scheme diagram is drawn according to the running results. Finally, on the basis of solving the layout of the workshop, the thesis carries on the supplementary research, analyzes the key job units in the layout of the workshop, and establishes the simulation model for the key job area with the help of the systematic simulation tool of EM-PLANT. The bottleneck process of the factory is identified by the bottleneck analysis module in the software, and the corresponding bottleneck improvement scheme is put forward, and the effect is verified on the EM-PLANT simulation platform. It provides a theoretical reference for the continuous improvement of workshop layout and production operation.
