【摘要】：伴随着改革开放的深入和市场经济的发展，国内汽车制造业迎来前所未有的竞争，同时汽车零配件制造业也面临了国外汽车零配件制造行业的巨大挑战。国内汽车零配件制造企业欲在激烈的市场竞争中占得先机，需引进先进制造系统，实行生产模式转型，企业加快由粗放式向精益化模式的转型，，而生产布局设计是企业实现生产改革转型的前提，适应先进制造模式的生产布局可以确保企业合理有效地分配制造资源，增强企业应对市场需求多样化、响应灵敏化的能力，使企业在有限的空间内充分地发挥现代制造系统的制造潜力和综合管理潜力；另一方面能够使企业有效地控制生产成本、降低库存、提高生产效率和优化企业生产环境等。论文从汽车变速箱制造企业的角度，在了解公司需求和制造工艺前提下研究和探讨了变速箱工厂生产车间布局设计。文章首先阐述了车间布局设计和仿真的研究概况，并依次介绍了制造企业车间布局的概念、设施布局的形式原则、影响因素和车间布局的理论方法，注重地介绍了两种布局理论方法：系统布置设计（SLP）和遗传智能算法。进而结合前期调研准备工作时期搜集到的数据信息，运用SLP理论对车间布局中的作业单位进行了物流关系分析和非物流关系分析，充分考虑到变速箱的制造工艺特点和企业未来战略规划，通过赋权值分析作业单位之间的综合相关位置关系，并绘出了作业单位对综合位置相关图。在SLP定性分析的基础上，建立以控制车间物流成本为目标函数的数学布局模型。使用独特的多行车间布局编码方案和部分匹配交叉的遗传算法策略，在MATLAB软件开发平台编程遗传算法求解车间布局的数学模型，根据运行结果绘制车间布局方案图。最后，论文在求解出车间布局的基础上进行了补充研究，分析出了车间布局中关键作业单位，并借助EM-PLANT系统化仿真工具建立了针对关键作业区域的仿真模型，通过软件中瓶颈分析模块识别出工厂的瓶颈工序，提出了相应的瓶颈改善方案，在EM-PLANT仿真平台上进行了效果验证，为企业后续的车间布局和生产运行中的持续改善提供了理论参考。
[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.
