FMEA 4th 手册介绍概要1.ppt

Summary 总结 Are efforts made to regularly validate SOD values and identify improvements? Who is involved?有无定期验证SOD值并采取措施，哪些人参与了？ Are FMEAs primarily used to drive improvements or record them? FMEA是否首要用来推动改进还是充当记录？ Is FMEA data used to analyze risk and measure improvement?FMEA数据用于分析风险和衡量改进吗？ Does Top Management review and act upon data derived from FMEAs? 管理层定期回顾和基于数据之上采取行动吗？ Does all of the time and effort spent on FMEAs provide a return on investment?为FMEA付出的精力和努力带来了回报吗？ * FMEA 4th Edition * FMEA 4th Edition Glenn Schnauber January 6, 2008 FMEA 4th 手册介绍 What is an FMEA? A systematic group of activities intended to（团队活动）: recognize and evaluate the potential failure of a product or process and the effects of that failure识别潜在失效模式和后果 recognize and prioritize ALL potential causes of each failure. Note link to fishbone…所有潜在失效原因 assess risk throughout the entire process (not just manufacturing)评估风险 identify actions that could eliminate or reduce the chance of the potential failure occurring采取行动消除潜在失效模式 be a “living” document that should always be updated to reflect current conditions, including changes动态文件 FMEA Process objectives目标: The FMEA drives product and process improvements 推动改进 Addresses all high risk failure modes识别高风险失效模式 Used to develop control plans用于形成控制计划 Integrated with process flow diagram and the process control plan结合流程图和控制计划 Considers all major “lessons learned” (i.e., nonconforming product, warranty data, customer complaints, corrective actions, etc.)获取经验教训 Improvements in the 4th edition FMEA Manual第4版手册的改进: Changes in format with index for navigation索引目录的改变 New form examples for guidance用于解释的新例子 Focus on management involvement and support 管理层支持 More focus on the linkage of DFMEA and PFMEA强调了DFMEA和PFMEA的联系 Improved examples of ranking tables 改进了等级打分表 Significantly enhanced guidance and examples增加了例子和解释 Reduced emphasis on RPN 不再强调RPN值 Alternative approaches and methods，such as Fault Tree analysis引入了其它对失效原因和后果供选择的分析方法，如故障树 Chapter 1 - Introduction
