摘　　要：针对无失效数据单元部件的可靠性评估问题,首先采用专家评估的方式来确定其故障率,然后基于可能性测度的理论方法,分析了可靠性数据相互间的支持程度,确定了专家数据的综合评估权重;最后讨论了极小样本数据的可靠性评估方法,以专家评估数据作为先验数据,采用优先加权综合的方法确定了先验数据和后验数据的综合评估模型。To solve the reliability evaluation problem of the invalid data unit components,firstly,the failure rate is defined by the method of expert assessment,then based on the theory of probability measure,the support degree between reliability data was analyzed,and the expert data comprehensive assessment weights is determined.Finally,the reliability evaluation method about the tiny sample data is discussed,and according to the priori data of expert assessment data,the comprehensive evaluation model of priori data and posteriori data was built by the method of prior weighted comprehensive.
