摘要
进行故障模式危害性分析涉及的信息多为一些不确定信息,分析结论通常为定性结论,较难用数学公式计算出数值结果。文章将灰色评估理论和专家评估方法相结合,对水下航行器(UUV)导航系统故障模式的危害性进行综合评估分析,得到导航系统各种故障模式危害性的定量分析结论,用于指导对故障的改进。
The information in criticality analysis（CA） for failure mode is uncertainty.It is difficult to obtain the accurately conclusion by mathematic method.A method is introduced in this paper,which combines the grey system theory and the experts＇ appraisal,this method can sum up the scattered information provided by every appraiser into a definite appraised value.and it is used in CA for navigating system of the unmanned underwater vehicle（UUV）.The conclusion can be used to guide the failure improving.
