Place Slide Title Here,USE THIS OCCASIONALLY FOR SECOND TITLE(CAPS ONLY),Use this level,First Bullet Level,Second Bullet Level,*,Failure Modes and Effects Analysis,Failure Modes and Effects Analysis(FMEA),潜在失效模式及影响,分析,Introduction,介绍,A process potential FMEA is an analytical technique utilized by a manufacturing responsible engineer/team as a means to assure that,to the extent possible,potential failure modes and their associated causes/mechanisms have been considered and the engineers/teams thoughts(including an analysis of items that could go wrong based on experience and past concerns)as a process is developed.This systematic approach parallels and formalizes the mental discipline that an engineer normally goes through in any manufacturing planning process.,过程,的,FMEA,是负责,制造,生产的工程师/队伍使用的分析,技,法，用来,在一定程度上,确保,潜在,的,失效模式,和相关的原因/机,制,都已考虑到，,以及,工程师/队伍的想法（包括基于经验和过去的想法得出的可能,失效项目,分析）。这种系统性的方法将工程师在任何生产计划过程中通常会碰到的问题,标准,化了,。,2,The Process potential FMEA,Identifies potential product related process failure modes.,确认与产品有关的过程失效模式,Assesses the potential customer effects of the failures.,评估失效对客户潜在的影响,Identifies the potential manufacturing of assembly process causes and identifies process variables on which to focus controls for occurrence reduction or detection of the failure conditions.,确定潜在的制造原因和过程变数，以便加以控制，减少发生,可能性,，增加,发现,到的可能性,Develops a ranked list of potential failure modes,thus establishing a priority system for corrective action considerations.,列出潜在失效模式的排行表，建立一个优先系统以做出改善行动,Modify manufacturing or assembly process.,改变,生产或生产线过程,3,FMEA Step,步骤:,1.,Define the scope for the FMEA,定义,FMEA,的范围,2.Identify team members,customer,and knowledge experts,确认队伍成员、客户，和专家,3.Develop roles and responsibilities for team members,制定每个成员的任务和职责,4.Study the product/process/service,研究产品/制程/服务,5.Brainstorm failure modes,known and potential,集体讨论,已知的和潜在的失效模式,6.List the effects,causes,and current controls for each failure mode,列出影 响、原因和,失效模式,当前控制情况,7.Assign ratings for Severity,Occurrence,and Detection,给,严重性、发生率、,发现度,的,评分,8.Calculate RPN,计算,RPN,9.Decide on a threshold RPN,制定采取行动的,RPN,界限值,10.Prioritize based on RPN and severity,or as required by the customer,优先性要根据,RPN，,严重性，或客户的要求,11.Identify corrective actions,确认,改善行动,12.Implement and verify effectiveness of corrective action,执行并确认,改善行动,的有效性,13.Complete the documentation,完成文件记录,4,Define the scope for the FMEA,定义,FMEA,的范围,Define the boundaries within which the product,process,or service will be studied,identifying the operating assumptions,current conditions and constraints.,定义产品、制程或服务的研究范围，确认,运,作前提，当前条件和约束。,5,2.,Identify team members,customer,and knowledge experts,确认队伍成员、客户和专家,Get the team together,identify the customer and involve them in the process.Some preliminary work must be done to understand the product/process/service,so the right team can be assembled.,将成员集合，确认客户并使他们参与进来。为了很好地理解产品/制程/服务，一些先前工作要做,，已使小组集合起来,。,6,3.,Develop roles and responsibilities for team members,制定每个成员的任务和职责,Who does what on the team.Clearly define the roles and responsibilities for each of the team members.At this time,it is important to consider the strengths of each individual and leverage the same.,谁做什么，清楚地定义每个成员的职责。这时，考虑每个人的长处很重要。,Example:Team Leader:*Coordinate the activities of the team,and keep on track,例：队长 协调队伍的活动，时时追踪,*Act as cheer leader,and interface with management,充当鼓舞者与管理相结合,*Ensure the decisions are made with consensus,确保和大家一起做决定,Customer :*Define requirements,定义需求,客户,*,Participate in developing rating scales,especially for,Severity Knowledge,参与等级制定，尤其是严重性,Expert:*As consultant provide info on details of product/,专家,process or service,作为顾问提供产品等信息,7,4.,Study the product/process/service,研究产品/制程/服务,The objective of this step is to acquire as much knowledge as possible.,It is highly recommended that all team members delve into this,since there is no other way to familiarize yourself with the product/process/service.,此步骤的目的是为了尽可能多的获取知识。,高度,建议所有成员都参与，因为没有其他的方式使你去熟悉产品/制程/服务。,8,5.Brainstorm failure modes,known and potential,集体讨论,已知的和潜在的失效模式,*Failure modes should be described in“physical”or technical terms,not as a symptom noticeable by the customer.,失效模式应描述为物理量或技术术语，而不是简单的表面现象,*,The idea is to identify as many failure modes as possible.This will involve getting all team members and stake holders involved,however,the proper approach to brainstorming must be used.Defer all judgment,maybe even to a subsequent meeting.,确认尽可能多的,失效模式,，使所有的成员都参与。使用,适当的脑力震荡,方法。,所有的调节整理留给以后的会议,。,*,The biggest risk in this step is that participants will start mixing up failure modes with causes,and effects.To prevent this,it is highly recommended that meeting leader do a dry run to familiarize the group with the differences between failure modes,effects,and causes.A listing of the product/process/services specifications,or outputs and requirements will benefit here.,最大的风险是参与者会混淆,失效模式,、原因和影响。建议会议领导者做个排练，使大家熟悉,失效模式,、原因和影响的差别。产品/制程/服务的,规格,，,产出,或需求,会对此,有所帮助。,*,Post it pads are a convenient way of collecting this information,and grouping it i
