Failure Modes and Effects Analysis (FMEA)的意思?

Failure Modes and Effects Analysis (FMEA)的意思?
答案是:失效模式与影响分析
--------------
参考一下:
失效模式与影响分析 简称FMEA (failure modes and effects analysis),由失效模式(FM)和影响分析(EA)两部分组成.
失效模式(FM)是指能被观察到的错误和缺陷现象,如操作程序不正确,线路接触不良,产品开裂等;影响分析(EA)是指通过分析该失效模式对系统的安全和功能的影响程度,提出可以或可能采取的预防改进措施,以减少过程缺陷,提高过程质量的技术.
简言之,做FM是发现问题;做EA则是分析问题并解决问题.
二.FMEA的特点及作用
1.FMEA的特点
FMEA的特点是将失效模式的严重度(SEV Severity),发生的频度(OCC Occurrence),不易探测度(DET Detection)三个方面进行量化;通过量化,识别潜在的失效模式,确定并优先选定措施,对潜在的失效模式及其影响进行预防,防患于未然.
