发布时间：2019-03-03 18:21
【摘要】：经济全球化的不断深入使得企业面临着越来越大的竞争压力。在激烈的竞争环境中，企业在追求低成本、高效率的同时希望能够为客户提供高质量的产品，愈来愈多的管理者开始关注“精益的速度”与“六西格玛的质量”之间的融合问题，即精益六西格玛管理法。众多中国企业也纷纷开始积极探索精益六西格玛管理法,然而能真正成功实施精益六西格玛的却并不多见。国内对精益六西格玛管理的研究主要停留在理论层面，如何同中国企业的发展实践相结合，形成一套具有中国特色的精益六西格玛管理方法是困扰许多企业的难题。 本文首先在对国内外相关研究进行综述的基础上，详细论述了精益生产管理和六西格玛管理的主要内容及工具方法，，并介绍了精益六西格玛管理的理论体系，提出精益六西格玛管理的改善流程DMAIC II。本文的研究主要围绕A公司提升130DB机种变压器的制程直通率来展开，介绍精益六西格玛管理工具DMAIC II在产品质量改进中的具体运用。在定义阶段，运用精益生产原理，注重价值流程分析，识别关键质量特性，确定改善范围和项目目标；在测量阶段，通过对Y的测量系统分析、过程能力分析、FMEA分析之后，对于简单的影响因素X用精益改善快速处理，而复杂的影响因素X则进入分析阶段；在分析阶段，针对复杂影响因子X采用二元ANOVA方法和筛选DOE方法判断因子的显著性；在改善阶段，通过量化DOE实验和因子RSM分析方法来得到最佳因子参数，从而确定最佳改善方案，同时运用精益现场管理对生产环境进行全方位优化；在控制阶段，确认项目改善效果，对项目效益科学评估，建立合理的控制计划，进行标准化处理。 本文在前人研究的基础上提出了精益六西格玛管理的理论体系，并归纳总结了精益六西格玛管理工具DMAIC II在产品质量改进中的具体应用步骤，对国内中小企业成功推广实施精益六西格玛管理有一定的借鉴意义。
[Abstract]:With the deepening of economic globalization, enterprises are facing more and more competition pressure. In the fierce competitive environment, enterprises in pursuit of low-cost, high-efficiency, while hoping to provide customers with high-quality products, More and more managers begin to pay attention to the integration of Lean Speed and quality of six Sigma, that is, Lean six Sigma Management method. Many Chinese enterprises have begun to explore Lean six Sigma management method, but few of them can implement Lean six Sigma successfully. The domestic research on Lean six Sigma Management is mainly on the theoretical level. How to combine with the development and practice of Chinese enterprises to form a set of Lean six Sigma Management methods with Chinese characteristics is a difficult problem that puzzles many enterprises. Firstly, on the basis of summarizing the related research at home and abroad, this paper discusses the main contents and tools of Lean production Management and six Sigma Management in detail, and introduces the theoretical system of Lean six Sigma Management. The improvement process DMAIC II. of Lean six Sigma Management is put forward. The research of this paper mainly focuses on improving the process pass-through rate of 130DB transformer by Company A, and introduces the application of Lean six Sigma management tool DMAIC II in the improvement of product quality. In the definition stage, use the lean production principle, pay attention to the value flow analysis, identify the key quality characteristics, determine the improvement scope and project objectives; In the measurement stage, after the measurement system analysis, process capability analysis and FMEA analysis of Y, the simple influence factor X is improved and processed quickly, while the complex influence factor X enters the analysis stage. In the analysis stage, using binary ANOVA method and screening DOE method to judge the significance of the complex influence factor X; In the improvement stage, the best factor parameters are obtained by quantitative DOE experiment and factor RSM analysis, and the optimal improvement scheme is determined. At the same time, the lean field management is used to optimize the production environment in an all-round way. In the control stage, confirm the project improvement effect, scientifically evaluate the project benefit, establish the reasonable control plan, and carry on the standardization processing. Based on the previous research, this paper puts forward the theoretical system of Lean six Sigma Management, and summarizes the concrete application steps of Lean six Sigma Management tool DMAIC II in the improvement of product quality. To the domestic small and medium-sized enterprises successful promotion implementation Lean six Sigma management has certain reference significance.
