【摘要】：六西格玛管理起步于摩托罗拉公司,经过多年的实践应用,被世界上众多企业所采用并获得了良好经济效益的,以数据分析为基础,减少缺陷,节约成本,提高顾客满意度的一种管理理念和方法。Z企业集团现已成为国内最大的木器家具涂料研发、生产、销售企业,作为涂料行业水性木器涂料的领先企业,如何保证水性木器涂料产品质量的稳定性,提升水性木器涂料质量水平,主要是光泽度一次检验合格率问题,已成为公司发展面临的主要问题,提高产品质量的一致性是当前日益严峻的环保压力下行业得到快速“油转水”的基础。基于这样的背景下,选取了水性木器涂料光泽度质量项目作为本论文的应用研究课题。本论文首先介绍了基于当前涂料行业在环保升级的大环境下,企业产品转型升级过程中的论文选题背景和实践意义,介绍了六西格玛管理以及在国内外的成功应用经验,并详细描述了六西格玛管理的起源和发展进程。同时介绍了木器涂料行业的主要情况、面临的主要问题,对z企业实施六西格玛管理进行了必要性分析。最后通过z企业水性木器涂料光泽度一检合格率质量改善为对象,通过运用定义(define)、测量(measure)、分析(analyze)、改进(improve)、控制(control)五个阶段构成的过程改进方法来提升目前z企业水性木器涂料产品生产过程中光泽度一检合格率偏低的问题。在定义阶段,根据水性木器涂料工艺流程,识别了光泽度质量问题,组建了六西格玛项目团队,运用高端流程图(sipoc)来识别质量问题产生的环节。在测量阶段,运用企业生产流程图、因果图确定影响光泽度质量问题的因素,并制定了数据收集计划,利用单因素方差分析等手段评估了测量系统的有效性,确保测量结果的准确性和精确度。在分析阶段,运用运行图、xbar-s控制图对生产过程稳定性、过程能力进行了分析,最终通过相关性分析、回归分析的方法确定了影响水性木器涂料光泽度质量问题的关键因素。在改善阶段,对关键因素针对性制定了解决方案,试运行结果达到了预期的目标。在控制阶段,通过优化工艺流程、修改作业指导书、培训等方式将成功做法标准化。通过六西格玛管理理论在z企业水性木器涂料光泽度一检合格率质量管理中的应用研究,寻找出影响产品一检合格率原因,从而针对性提出了解决方案,在企业的实践运行中证明是可行的、有效的,为下一步Z企业六西格玛活动的开展和质量水平的提升积累了宝贵的经验。为当前国家所倡导的供给侧改革,产品的转型升级、也为民营涂料企业逐步做大做强的探索提供了可供参考的经验。
[Abstract]:Six Sigma management started from Motorola Company. After many years of practice and application, it has been adopted by many enterprises in the world and obtained good economic benefits. Based on data analysis, it can reduce defects and save costs. A Management concept and method to improve customer satisfaction. Z Enterprise Group has become the largest enterprise in China in the field of wood furniture coatings research and development, production and sales, as a leading enterprise in the paint industry of water-based wood coatings. How to ensure the stability of waterborne wood coatings product quality and improve the quality level of waterborne wood coatings, mainly the problem of gloss inspection pass rate, has become the main problem facing the development of the company. Improving the consistency of product quality is the basis of rapid oil to water transfer under the increasingly severe pressure of environmental protection. Based on this background, waterborne wood coating gloss quality project is selected as the application research topic of this paper. This paper first introduces the background and practical significance of the thesis in the process of product transformation and upgrading under the environment of environmental protection upgrade in the paint industry, and introduces the six Sigma management and successful application experience at home and abroad. The origin and development of six Sigma management are described in detail. At the same time, the main situation and problems of wood coatings industry are introduced, and the necessity of implementing six Sigma management in z enterprise is analyzed. Finally, through z enterprise waterborne wood coating gloss, the quality of qualified rate is improved. By using the process improvement method of defining, measuring, analyzing, improving and controlling five stages, the problem of low gloss and pass rate in the production process of waterborne wood coatings in Z enterprise is improved. In the definition stage, according to the waterborne wood coating process, the gloss quality problem was identified, and the six Sigma project team was set up to identify the links of the quality problem by using the high-end flowchart. In the measurement stage, the factors influencing the gloss quality are determined by using the enterprise production flow chart and causality diagram, and the data collection plan is worked out, and the effectiveness of the measurement system is evaluated by means of single factor variance analysis, etc. Ensure accuracy and accuracy of measurements. In the stage of analysis, the stability and capability of the production process were analyzed by using the control chart of operation diagram xbar-s. Finally, the key factors affecting the gloss quality of waterborne wood coatings were determined by means of correlation analysis and regression analysis. In the stage of improvement, the solution of key factors is worked out, and the test results reach the expected goal. In the control phase, the successful practices are standardized by optimizing the process flow, modifying the operation instruction, training and so on. Through the application research of six Sigma management theory in the quality management of the gloss of water-borne wood coatings in z enterprise, the reasons that affect the qualification rate of the first inspection of products are found out, and the solutions are put forward. It is proved to be feasible and effective in the practical operation of enterprises. It accumulates valuable experience for the development of six Sigma activities and the improvement of quality level in Z enterprise. For the current national advocate of supply-side reform, product transformation and upgrading, but also for the private paint enterprises to gradually larger and stronger exploration to provide a reference experience.
