摘　　要：在利用Bayes理论进行小子样可靠性评定过程中,为了尽可能少做现场试验,必须充分利用各种先验信息,多源先验信息的融合是小子样理论方法应用中亟待解决的一个问题。基于分布图方法,提出了分布图多源信息融合技术,建立了基于分布图信息融合的Bayes可靠性评定模型。仿真实例验证了方法的合理性和有效性。The reliability analysis and evaluation for system in small sample circumstance, the Bayesian method is adopted as an important and suitable approach. In order to reduce the testing data, the all kinds of prior information must be used, so the fusion of information of multiple sources is a key problem in Bayesian analysis practically. A new method based on the distributing chart theory to realize the fusion of information of multiple sources was proposed, and the model of Bayesian reliability analysis was established. The simulation example shows that the method proposed is effective.
