探讨了因设备失效而可能造成人员大量伤亡或财产严重损失的可靠性风险分析方法问题。指出了失效模式与效应分析 ;失效严重度分析和失效树分析均是可靠性风险分析的主要方法和有效工具。文章对失效模式、效应、严重度分析和故障树分析进行了比较和研究 ,得到了在可靠性风险分析时这些方法是相辅相成的结论。
This paper discusses the reliability risk analysis method which may cause heavy casualties or serious property loss due to equipment failure. The failure mode and effect analysis are pointed out. Failure severity analysis and failure tree analysis are the main methods and effective tools for reliability risk analysis. The article compares and studies the failure modes, effects, severity analysis and fault tree analysis, and obtains the conclusion that these methods are mutually reinforcing in the reliability risk analysis.
