[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.
