Reliability analysis on zero-failure data of missile power system

According to the character of certain missile power system zero-failure data, this paper presented Bayesian estimation method of zero-failure under entropy error loss. Firstly, we discussed Bayesian estimation of fixed-time censored data. Secondly, we obtained Bayesian estimation of zero-failure data by considering zero-failure data as the result of fixed-time censored test one by one. Using correlative theorem we proved the admissibility of the estimator. Finally, we made reliability analysis on a certain missile engine, and the result showed that this method is rational.
