【摘要】：本课题为应用型案例研究,K公司是典型的轻资产跨国集团公司,95%的配件是从国外采购,其中有关键部件P在中国采购,但质量问题一直较多,公司拟推行六西格玛管理来提高部件P的质量。在六西格玛(6σ)管理项目实施过程中,本文采用六西格玛改进的统一标准:DMAIC,即定义、测量、分析、改善和控制五个过程阶段,在每个过程阶段的推进过程中,还采取一些六西格玛方法的常用工具和分析手段,如:排列图-即帕累托图(Pareto),过程能力指数(CPK),鱼骨图,程序流程图(SIPOC),测量系统分析(MSA),方差分析(ANOVA)等等。本文通过六西格玛管理理论和方法在供应商实际生产中的成功应用,使外购产品P的CPK由改进前三西格玛以下的质量水平提高到改进后的四西格玛以上的质量水平,产品P的焊接不良明显下降。通过品质的提升,在供应商处产生经济效益约71万元,K公司的组装产品质量明显提高。六西格玛持续改进DMAIC法应用在供应商零部件品质改进方面是帮助企业自身质量战略的重要工具,它不单纯是技术方法的应用,更是一种全新的互利共赢合作模式。
[Abstract]:This paper is an applied case study. The company is a typical light assets multinational group company. 95% of the accessories are purchased from abroad. Among them, key parts P are purchased in China, but there are many quality problems. The company intends to implement six Sigma management to improve the quality of component P. during the implementation of the six Sigma 6 蟽) management project, this paper adopts the six Sigma improved Unified Standard: DMAIC-Definitions, Measurement, Analysis, improvement and Control five process stages, I. e., definition, Measurement, Analysis, improvement and Control. Some common tools and analytical tools of the six Sigma method are also used in the advancement of each stage of the process, such as the permutation diagram-Pareto map, the process capability index (CPK), the fish bone map. In this paper, the six Sigma management theory and method are successfully applied in the production of the supplier through the six Sigma management theory and method, and so on, such as the flow chart of the program, the measurement system analysis, the ANOVA and so on. The CPK of product P is improved from the quality level below three sigma before improvement to the quality level above four sigma after improvement, and the welding defect of product P is obviously decreased. The quality of assembly products of 710000 Yuan / K company has been improved obviously. Six Sigma continuous improvement DMAIC method is an important tool to help the enterprise to improve its own quality strategy in the aspect of supplier parts quality improvement. It is not only the application of technical methods, but also a new mode of win-win cooperation.
