故障模式与影响分析

Failure Mode and Effects Analysis

故障模式与影响分析是一种可靠性设计的重要方法,它对各种可能的风险进行评价、分析,以便在现有技术的基础上消除这些风险或将这些风险减小到可接受水平,已经成为提高产品可靠性重要的途径,得到广泛的应用。文章首先分析软件的错误、缺陷、故障、失效之间的关系,进一步得出故障模式的定义。根据不同的角度将故障模式进行分类,并从影响性、危害性等多个方面分析故障模式。

Failure Mode and Effects Analysis is an important method for reliability design, it can assessment and analysis all possible risks. In order to eliminate these risks on the basis of existing technologies or reduce these risks to an acceptable level, it has become an important way to improve product reliability. The article first analyzes the relationship between software error, defect,failure, further get the definition of failure mode. classification the fault depending on the different angle, and analysis failure mode by the impact and hazardous and so on.
