【摘要】：近些年,随着我国经济的迅速发展,人民生活水平有了很大的提高,汽车成为日常代步工具,汽车需求量急剧攀升。为汽车零部件行业的发展提供了庞大的市场基础和良好的市场环境,同时也吸引着大量外资企业注入,汽车零部件企业间竞争加剧。如何提高企业竞争力,成为了我国汽车零部件企业生存和发展的关键,企业除了加强技术研发之外,对于生产管理模式的优化同样重要,因此生产管理模式成为了众多学者的研究焦点。本文以A公司为例,对精益六西格玛管理模式的实施进行了研究。首先对国内外精益六西格玛相关理论现状进行了研究,详细阐述了精益生产和六西格玛两种管理方法的核心内容和工具,根据两种管理方法的整合研究现状,介绍了精益六西格玛管理理论及其实施流程。其次,对A公司现状进行了研究,分析了A公司作为汽车零部件重点企业率先践行精益六西格玛管理的必要性。根据A公司当前生产系统管理现状,分析了实施精益六西格玛的可行性。再次,按照精益六西格玛DMAIC流程在A公司实施精益六西格玛改善。分析客户声音和需求,确定出优先实施精益六西格玛的项目内容:针对离合器盖总成装配线,以提高生产效率、降低废品率为目标进行改善;综合利用价值流分析、流程分析、生产线平衡分析和失效模式分析等方法,找出导致生产效率低、废品率高的根本原因;应用程序分析、作业分析、快速换模、混合拉动系统等精益生产工具对生产系统进行优化,制定出了适合A公司的改进方案。最后,利用Flexsim软件分别对改善前后的离合器盖总成装配线进行了仿真,对比分析仿真结果,生产效率明显提高,降低了不良品产生的可能性。期待本文能够为汽车零部件企业实施精益六西格玛提供借鉴和参考。
[Abstract]:In recent years, with the rapid economic development of our country, people's living standards have been greatly improved. The rapid increase in automobile demand provides a huge market foundation and a good market environment for the development of the auto parts industry, and at the same time attracts a large number of foreign-funded enterprises to inject. How to improve the competitiveness of automobile parts enterprises has become the key to the survival and development of auto parts enterprises in China. In addition to strengthening technology research and development, enterprises are also important for the optimization of production management mode. Therefore, the production management model has become the research focus of many scholars. This paper takes A Company as an example to study the implementation of Lean six Sigma management model. Firstly, the current situation of Lean six Sigma theory at home and abroad is studied. The core contents and tools of Lean production and six Sigma management methods are described in detail. According to the present situation of research on the integration of the two management methods, the Lean six Sigma management theory and its implementation process are introduced. The present situation of Company A is studied, and the necessity of A Company, as a key enterprise of automobile parts, to take the lead in Lean six Sigma Management is analyzed. The feasibility of implementing Lean six Sigma is analyzed. Thirdly, lean six Sigma improvement is implemented in A Company according to Lean six Sigma DMAIC process. Determine the priority of Lean six Sigma project content: for clutch cover assembly line, to improve production efficiency, reduce the rate of waste products, comprehensive use of value flow analysis, process analysis, Production line balance analysis and failure mode analysis to find out the root cause of low production efficiency, high waste rate, application program analysis, job analysis, rapid mold change, Lean production tools, such as hybrid pull system, optimize the production system and work out an improvement scheme suitable for company A. finally, the assembly line of clutch cover assembly before and after improvement is simulated by Flexsim software. By comparing and analyzing the simulation results, the production efficiency is obviously improved, and the possibility of producing bad products is reduced. It is expected that this paper can provide reference and reference for automobile parts enterprises to implement Lean six Sigma.
