Abstract  Hierarchical Bayesian method for estimating the failure probability pi under DOOF by taking the quasi-Beta distribution B(pi-1,1,1,b) as the prior distribution is proposed in this paper. The weighted Least Squares Estimate method was used to obtain the formula for computing reliability distribution parameters and estimating the reliability characteristic values under DOOF. Taking one type of aerospace electrical connector as an example, the correctness of the above method through statistical analysis of electrical connector accelerated life test data was verified.

Key words： DOOF data      Hierarchical Bayesian estimate      Reliability analysis
