主　　题：Aerospace relay Belief rule base Expert knowledge Fault diagnosis Interpretability constraints 

摘      要：It is vital to establish an interpretable fault diagnosis model for critical *** Rule Base(BRB)is an interpretable expert system gradually applied in fault ***,the expert knowledge cannot be utilized to establish the initial BRB accurately if there are multiple referential grades in different fault *** addition,the interpretability of BRB-based fault diagnosis is destroyed in the optimization process,which reflects in two aspects:deviation from the initial expert judgment and over-optimization of *** solve these problems,a new interpretable fault diagnosis model based on BRB and probability table,called the BRB-P,is proposed in this *** with the traditional BRB,the BRB-P constructed by the probability table is more ***,the interpretability constraints,i.e.,the credibility of expert knowledge,the penalty factor and the rule-activation factor,are inserted into the projection covariance matrix adaption evolution strategy to maintain the interpretability of BRB-P.A case study of the aerospace relay is conducted to verify the effectiveness of the proposed method.
