【摘要】 近年来汽车继电器的使用量呈现逐年快速增长趋势,市场对K公司生产的汽车继电器质量要求也越来越高。K公司继电器产品不导通问题是对外部客户影响最大的质量问题,也是被抱怨投诉频率最高的质量问题。论文将六西格玛管理应用于K公司继电器产品的质量管理,以求达到提高产品质量及持续改善的目的。论文从六西格玛培训体系和六西格玛管理制度建立两方面导入六西格玛管理系统,并将六西格玛管理方法应用到不导通问题质量管理改善的实施。通过组织制定计划、定期评审和对存在或可预见的困难进行分析解决以提前预防或降低项目失败风险来管理指导DMAIC各阶段工作。通过以下逻辑方法引导不导通项目的管理改善实施:首先通过对不导通样品进行深入分析,识别出导致不导通的主要异物。其次,通过SIPOC、微观流程图、因果矩阵、FMEA等质量管理工具,层层聚焦并识别出:带入、产生异物的关键因子和影响异物去除能力的关键因子。再次,论文利用DOE和ANOVA分析工具对关键因子进行分析,分析出高贡献度关键因子的最佳水准并对其进行管控,同时,针对部分关键因子产生的相互矛盾问题,利用TRIZ工具找到创新的改善方法和措施。最后,对导入的措施标准化并对部分关键因子开展在线SPC管控,同时将有效措施水平展开到其他类似线体。K公司通过实施六西格玛管理,不仅大大提升产品质量,也大大提升了团队成员发现、分析和改善质量问题的速度和能力。论文的研究结论为其他相关企业提供了一定的借鉴作用。更多还原

【Abstract】 In recent years,the use of automotive relays has shown a rapid growth trend year by year,and the market demand for the quality of automotive relays manufactured by K Company is also getting higher and hquality igher.K company relay product non-conduction problem is the most influential problem to external customers,and also the quality problems of the highest frequency complained.Six sigma management is applied to the quality management of relay products in Company K in order to improve product quality and continuous improvement.This thesis introduces the six sigma management system from two aspects:the training system of six sigma and the establishment of six sigma management system,and applies the six sigma management method to the implementation of quality management improvement of non-conductive problems.To manage and guide all stages of DMAIC work by organizing plans,periodic reviews and analyzing and resolving existing or foreseeable difficulties in order to prevent or reduce the risk of project failure in advance.Through the following logical methods to guide the management improvement and implementation of non-conductive projects.Firstly,through in-depth analysis of non-conductive samples,the main particles leading to non-conduction are identified.Secondly,through quality management tools such as SIPOC,micro-flow chart,cause and effect matrix,FMEA,we focus on and identify the key factors that bring in and produce particles and the key factors that affect the removal ability of particles.Thirdly,the thesis uses DOE and ANOVA analysis tools to analyze the key factors,analyze and identifies the best level of the key factors with high contribution and controls them.At the same time,aiming at the contradiction of some key factors,the thesis uses TRIZ tools to find innovative improvement methods and measures.Finally,the thesis standardizes the imported measures and makes SPC control on-line and horizontal expansion to other similar lines.By implementing six sigma management,K Company not only improves the quality of products significantly in the process of solving quality problems,but also greatly improves the speed and ability of team members to discover,analyze and improve quality problems.The conclusion of this thesis provides some reference for other related company.更多还原
