Hierarchical Bayesian method for estimating the failure probabilityp
i under DOOF by taking the quasi-Beta distributionB(p
i−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.
