【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。
[Abstract]:With the popularization and development of urban high-rise buildings, elevator safety accidents occur from time to time. People pay more and more attention to the safety and reliability of elevator products. Under this background, this paper takes SEP Company as an example to study the application of six Sigma management. Based on six Sigma quality management theory, this paper analyzes the current situation and existing problems of quality management in SEP Company. Using the DMAIC process improvement model, this paper studies the process improvement and methods of the project definition, measurement, analysis, improvement and control, including the establishment of project objectives and the creation of a project team. Make project plan, transform customer voice into quality evaluation index; To test the reliability and accuracy of the measurement system, the methods of brainstorming, causality analysis (fish bone map), potential failure mode analysis (FMEA) and Plato are used. Through test and verification, three key factors affecting the distortion degree of elevator door plate are found out, and corresponding improvement and control measures are taken. It is found that the number of DPPMs per million defects is improved. The leveling of distortion and the level of Sigma are close to the target value of the project, which basically achieves the expected financial revenue target, while reducing customer complaints. For the use of DMAIC tools. In the aspects of project team building and training, some suggestions are put forward to improve the management level of six Sigma. The research results of this paper have reference and reference value for elevator manufacturing and other related enterprises to carry out six Sigma management.
