摘　　要：探讨了一种在产品设计比较成熟且有足够现场使用数据的前提下的侧重失效影响统计的FMEDA方法,并通过马尔科夫模型对FMEDA数据进行后处理,得到量化的可靠性指标,以更快速、更准确的评估核电阀门设备的安全可靠性。This article is presenting a modified FMEDA method which is more emphasize on the possi- bility of occurrence of certain failure effect rather than the occurrence of component failure. Markov model is also introduced in this article for post - process the data generated during FMEDA. It can be significantly efficient for safety ＆ reliability evaluation of nuclear valve with the quantified output of Markov model.
