In view of the high cost for verifying the reliability of high-valued ammunition fuzes with complete-round flight test,it is proposed to determine inheritance factor by chi-square goodness-of-fit.A Bayes method of reliability evaluation for fuzes is put forward based on mixed beta distribution as the prior distribution,which solves the problem of data fusion between simulation and field test.Reliability of a certain foreign fuze is estimated with the given method,showing that the specimens using in the field test are one-third fewer than the specimens with the typical method.
