【摘要】 质量改进是任何企业永恒的话题,质量就是企业的生命线。在南普公司,一家推行精益化生产,准时交付,以顾客满意为终极目标的加工型企业而言,显得尤为重要。质量诊断流程图(QCPC)是南普公司在推行精益化生产中的重要工具之一,其目的是通过对系统或流程中产生的反馈点进行搜集,并关注最高反馈,然后展开对最高反馈的质量诊断,找到根本原因,并将根本原因链接到相关的流程或标准作业上,利用错误预防的理论制定有效的纠正措施。论文对南普公司叶轮线的质量诊断流程图的应用设计及应用研究,主要工作如下：(1)通过对南普公司经营状况及质量状态分析,得出叶轮线是对公司质量业绩影响最大的因素,并说明实施质量改进的必要性。(2)根据南普公司叶轮零件线的生产现状,以质量诊断流程图的相关理论为基础,进行系统的质量数据和反馈收集,然后通过数据分析,确定其质量改进项目的优先等级。(3)通过项目设置、团队组建、目标设定等方式来管理改进项目,然后使用冷酷无情分析法的方式找到相应的根源问题,并依照错误预防理论制定相应的有效的纠正措施,以确保一劳永逸,从系统或流程上解决重复发生的质量问题。(4)最后提出了如何确保质量诊断流程图顺利实施的相关保障措施,并对实施的直接效果和间接效果进行评价。本文的研究对产品质量要求高,而且产品类型及工艺路线复杂的生产型企业具有较高的参考价值和借鉴作用,对其它非加工型企业的质量诊断也有很好的借鉴意义。更多还原

【Abstract】 Quality improvement is a permanent hot topic in any kinds of enterprise, the existence of company depends on quality. At South Pratt&Whitney Aero-Engine Company, which implements lean production, focus on on-time delivery and take customer satisfaction as the final target of the company, excellent product quality becomes more important. Quality Clinic is one of the most important tools during the lean production implementation, the intent of quality clinic is to collect feedbacks or turn-backs and focus on top offenders. And then conduct quality clinic for those top offenders, to find out the root causes and effective corrective actions, the root causes always link to related process and standard works, the corrective actions always incline to implement level one mistake proofing. The article is focusing on the quality clinic process chart design and research of implementation, the main working contents and results as below:(1) Analyze the South Pratt&Whitney Aero-Engine Company’s business running situation and quality performance get the conclusion that, IMP Line is the top offender and it is necessary to improve product quality.(2) According to the Critical manufacturing line operation running and quality performance, base on the theoretical of quality clinic process chart, to collect the quality data and issues systematically, to clarify the key issues need to be improved.(3) By implementation of the six steps of quality clinic process chart on critical manufacturing line, they are:Initiate the QCPC Process, Summarize Detailed Turn-back Data, Analyze the Improvement Opportunities, Define Improvement Projects, QCPC/Clinic Activity, Communicate the Results. During the clinic cycle, RRCA will be introduced find out the root causes, and making effective resolutions systematically.(4) Finally, the article will introduce how we ensure this tool application and key metrics of QCPC result. This article is highly recommend for those enterprises which has very high quality requirements with complex manufacturing process, also it is beneficial for business unit which want to improve his business results.更多还原
