文档介绍:万方数据万方数据西安建筑科技大学硕士论文 SEP 公司六西格玛管理研究 专 业: 工商管理硕士生: 孔维锦指导教师: 刘 桦教授摘 要 随着城市高层建筑的普及和发展,电梯安全事故也时有发生,电梯产品的安全性和可靠性愈来愈受到人们的关注。电梯制造企业在获得市场发展机遇的同时, 也面临进一步提升其质量管理水平的挑战。在此背景下, 本文以电梯制造企业 SEP 公司为例,研究其六西格玛管理的应用,具有现实意义。 本文以六西格玛质量管理理论为基础,分析了 SEP 公司质量管理的现状和存在的问题。以电梯门板平整扭曲度改进项目为例,运用 DMAIC 过程改进模型,研究了该项目定义、测量、分析、改进和控制等各阶段的过程改进和方法。其中包括确定项目目标,创建项目团队,制定项目计划,把客户声音转化为质量评价指标;检验测量系统的可靠性和准确性,综合运用头脑风暴法、因果分析法(鱼骨图) 、潜在失效模式分析( FMEA )和柏拉图等方法,通过测试验证找出了影响电梯门板平整扭曲度的 3 个关键因素,有针对性地采取了改善和控制措施。研究发现,改善后每百万缺陷数( DPPM )、平整扭曲度( CPK )、西格玛水平等接近项目的目标值,基本实现了预期的财务收益目标,同时减少了顾客抱怨。针对 DMAIC 工具的使用、项目团队建设和培训等方面,提出了提升企业六西格玛管理水平的具体建议。本文研究成果对于电梯制造等相关企业推行六西格玛管理有借鉴和参考价值。关键词: 六西格玛; DMAIC ;电梯门板;平整扭曲度;过程能力万方数据万方数据西安建筑科技大学硕士论文 Research on Six Sigma Management by SEP Specialty: Business administration Name: Kong Weijin Instructor: Liu Hua Professor Abstract With the development and popularization of high-rise buildings in Chinese cities, the accidents of elevator have also occurred. In that case ,the security and reliability of elevator products have been paid more and more attention. It is not only an opportunity that elevator manufacturing enterprises ge t more and more market with economic development, but also elevator manufacturi ng enterprises have b een confronted with challenge of quality management level. In this context, Sematic Elevator Products (Suzhou) Co. ,Ltd (SEP) has been taken for an example as an elevator manufacturing enterprise, which is practical significance that the applicatio n of Six Sigma management in SEP has been researched. The existing problems belong to quality management in pany have been analyzed based on the Six Sigma quality management theory in this paper. The elevator door flatness- twist improvement project has be en taken for an example, and researched the project about definition, measurement, an alysis, improvement and control etc. by the improved model using DMAIC process. This include defining pr oject goals, creating the project team, project planning,
