| 摘 要： | 本文讨论指数部件可靠性的Bayes估计,对未知参数作了变换,从而使选择参数的验前分布更加灵活合理,在截尾测试下,分别讨论了验前分布为负对数Gamma分布与Beta分布的情况,获得了指数部件可靠性指标的表达式。无信息验前分布的情况,仅作为特例。最后,对无信息验前分布的情况给出了一个实例。

| Abstract: | This paper deals with Bayes estimate of reliability index for an exponential unit during truncation test. The unknown parameters are transformed so that the prior distribution of parameters can be chosen more flexibly and rationally. The situation that prior distribution being negative logarithmic gamma-distribution or beta-distribution is discussed respectively under truncation testing. The paper is ended with the non-information prior distribution, which is exemplified and con- sidered as a special case here. |
