RPNFMEA的输出.PPT

RPN:FMEA的输出,RPN的计算:潜在的失败模式（FM）失败模式的影响（FME）在一个制品到达顾客那里之前，发现失败模式（FM）的可能性。,RiskPrioritynumber:RPN,RPN=（严重度）Severity*（发生度）Occurrence*(检出度）Detection,RPN不是制品的原始值.,影响,原因,控制,RPN的计算,Recommendedaction,Responsibleperson,Finishdate,Actuallytakedaction,severity,occerrence,RPN,UsingStstisticaltool,BB2000/1/15,Samplingtestof1time,在对策实施或，输入变化后的结果,step13.活动职责-负责人.接触点.部门-完成日程,step14.对策实施-实际活动-日程step15.RPN计算-severity-occurrence-detection,detection,1,1,1,1,1,1,10,10,10,10,1,10,10,1,1,10,10,10,10,1,10,1,10,1,Noaction,Noaction,Action,一般情况,确保控制,主要问题,操作者未受失败影响,频繁的失败，检出，成本要求,occurrence,severity,detection,结果,行为,Quiz!(结果),Noaction,操作者受失败影响,Action,Action,Action,Action,频繁失败，操作者受影响,频繁失败，主要影响,如果RPN大于100或失败发生度，严重度，检出度大于8的评价等级需建立改善措施。在相关FMEA表格中标注*。如果不要求改善措施，在相关表格中标注NOR。,根据RPN采取的对策,6.ProcessFMEAchecklist,准备工作组成FMEA队?相关信息确认?Processmap（工序图）制作processmap?在每一道工序找出Y因子？在每道工序中作Y因子表格？一般项目基本项目都包括了吗？输入函数每一道操作都清楚地标明函数了吗？,FailureMode由FM可以清楚地得出这部分错了吗？一些由于FM造成的错误的特性表做出来了吗？在FM中包括的检出检查和试验的表?缺陷部分的接受度对好的制品的拒绝度如果FM对下一道操作有不好的影响.一个FM记录可以作为下一道操作的发生原因？一个失败在下一道操作中能区分出来吗?,失败影响对于设备，人员，顾客的危险影响考虑了吗？以下这些影响记录了吗？下一道操作下一个顾客,最终顾客传递方法政府限制条文失败原因/机理在工序中可能出现的错误记录了吗？工序特点考虑了吗？设计的弱点考虑了吗？每道操作中资材考虑了吗？操作人员考虑了吗？,当时的管理状况次品可以被检查出来在结束一道工序后次品可以别检出严重度根据FM标准的严重度分类了吗？它与顾客产生的影响一致吗？发生度预防控制考虑了吗？检出度在结束一道操作前，现有的控制条件下，根据检出的可能性可以决定吗？,等级分类-主要特征和特有的相关控制已经确认了吗？主要特征都由倒三角标识了吗？对于一个工序或某部分特征分析主要特征了吗？主要特征和相关特殊控制措施通知负责设计的人员了吗？RPN根据RPN大小顺序排列了吗？,建议考虑到的主要特征产生的严重不良，采取的对策降低这种不良了吗？对主要的特征进行特别控制了吗？所有的主要特征都考虑到拉吗？负责执行的人员指定了吗？优先考虑预防措施了吗？措施消除或减少了危险的FM了吗？,FMEA(example)-1,根据FMEA流程.主要工程录入变量：刻度精确度，DICY用蒸汽加热的水箱。,process,Primaryprocessinput,effect,cause,control,Failuremode,DICYtankheatedwithsteam,Scaleaccuracy,scale0,Scaleinaccurate,Scaleisnotsetwith0,FMEA(example)-2,根据录入的主要工程的变量，记录FM。,process,Primaryprocessinput,effect,cause,control,Failuremode,DICYtankheatedwithsteam,Scaleaccuracy,FillinglowDMF,FMEA(example)-3,记录由FM产生的影响。,process,Primaryprocessinput,effect,cause,control,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,FMEA(example)-4,WaterinJacket,Tankdelay,imperfectfilling,记录FM的原因。,FillinglowDMF,process,Primaryprocessinput,effect,cause,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,control,FMEA是在最初的控制里面找到最初的不良。,VisualcheckofJacket(SOP5681),Visualcheck(SOP5681),None,FMEA(example)-5,对每一个原因录入现有管理方法。,WaterinJacket,Tankdelay,imperfectfilling,FillinglowDMF,process,Primaryprocessinput,effect,cause,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,control,InstallationDMF,wrongDMFfilling,DMFinstallationaccuracy,FMEA(example)-6,Visualcheck(SOP5681),WaterinJacket,Tankdelay,imperfectfilling,FillinglowDMF,process,Primaryprocessinput,effect,cause,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,control,VisualcheckofJacket(SOP5681),None,Viscositydeviatedfromstandard,FMEA(example)-7,InstallationDMF,wrongDMFfilling,DMFinstallationaccuracy,Visualcheck(SOP5681),WaterinJacket,Tankdelay,imperfectfilling,FillinglowDMF,process,Primaryprocessinput,effect,cause,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,control,VisualcheckofJacket(SOP5681),None,None,Systemfailure,CantfollowSOPstandard,FMEA(example)-8,Viscositydeviatedfromstandard,InstallationDMF,wrongDMFfilling,DMFinstallationaccuracy,Visualcheck(SOP5681),WaterinJacket,Tankdelay,imperfectfilling,FillinglowDMF,process,Primaryprocessinput,effect,cause,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,control,Keep,repairprocedure(SOP5821)/visualcheck,Workercertification/processaudit,FMEA(example)-9,None,Systemfailure,CantfollowSOPstandard,Viscositydeviatedfromstandard,InstallationDMF,wrongDMFfilling,DMFinstallationaccuracy,Visualcheck(SOP5681),WaterinJacket,Tankdelay,imperfectfilling,FillinglowDMF,process,Primaryprocessinput,effect,cause,Failuremode,scale0,DICYtankheatedwithsteam,Scaleaccuracy,Scaleinaccurate,Scaleisnotsetwith0,FillinghighDMF,FillingwrongDMF,control,process/input,cause,occurrence,control,detection,RPN,severity,Failuremode,effect,VisualcheckofJacket(SOP5681),Visualcheck(SOP5681),None,DMFfilling/DMFinstalaccuracy,Workercertification/processaudit,scale0,Inaccuratescale,lowDMFfilling,wrongDMFfilling,3,3,3,7,7,2,2,2,2,5,1,6,3,9,3,5,18,54,42,175,highDMFfilling,FMEA(example)-10,由产生原因分配严重度，发生度，检出度等级。RPN计算,DICYtankheatedwithsteam,Scaleisnotsetwith0,wrongDMFfilling,Viscositydeviatedfromstandard,Systemfailure,CantfollowSOPstandard,WaterinJacket,Tankdelay,imperfectscale,Keep,repairprocedure(SOP5821)/visualcheck,wrongDMFfilling,7,5,5,175,Imperfectscale,None,3,2,9,54,Systemfailure,7,2,3,42,DMFfilling/DMFinstalaccuracy,Tankdelay,3,2,3,18,WaterinJacket,scale0,3,2,1,6,FMEA(example),RPN大小排列,process/input,cause,Occurrence,control,Detection,RPN,severity,Failurem
