| 摘 要： | 为了对指数分布场合无失效数据的失效率进行估计，在先验分布为截尾Gamma分布时，利用平均剩余寿命和极大似然思想提出了两种引进失效数据的方法，给出了失效率的综合多层Bayes估计，并且结合实际数据进行了计算，计算结果显示此种方法是可行的．

| Abstract: | In this paper, two kinds of method are put forward by making use of the average surplus life and maximum likelihood decision rule. When prior distribution of failure-rate is in form of the bobtail Gamma distribution, the synthesize hierarchical Bayes- ian estimation of the failure-rate in exponential distribution has come from zero-failure data. Finally calculation is performed regard- ing to practical problem and calculation result manifests that this kinds of method are viable. |
