潜在的失效模式及后果分析(FMEA)是为提高产品质量和可靠性的一种系统化的活动。在产品设计和过程设计阶段,对构成过程的各个工序以及构成产品的子系统和零部件逐一进行分析,找出所有潜在的失效模式,并分析其可能出现的后果,从而在事先采取必要的措施。因此,FMEA是一种“事前的行为”,事先进行综合的FMFA分析,能以较低成本 The potential failure mode and consequence analysis (FMEA) is a systematic activity to improve product quality and reliability. At the product design and process design stage, the various processes that make up the process and the subsystems and components that make up the product are analyzed one by one, all potential failure modes are identified, and their possible consequences are analyzed, so that necessary measures are taken in advance. . Therefore, FMEA is a kind of “preliminary behavior”, and a comprehensive FMFA analysis is conducted in advance, which can lower the cost.
