Abstract:

In this paper, for zerofailure data of exponential distribution, if the prior density kernel of the failure rate λ is in form of λa-1, the author gives λ Bayesian estimation and hierarchical Bayesian estimation. When for life distribution such as exponential distribution of certain hydraulic engine , the author gives, then the reliability estimation of certain hydraulic engine under zero-failure data condition is obtained also.
