中文摘要:

      本文利用近似Ｂａｙｅｓ方法对一个具有树形结构的成败型系统的可靠性进行估计．本文证明了利用近似Ｂａｙｅｓ方法对系统的可靠性参数的估计，具点估计在Ｆｉｓｈｅｒ意义下是渐近有效的，其相应的置信下限也是Ｆｉｓｈｅｒ意义下渐近有效的．

英文摘要:

      In this paper, an approximate Bayes method is employed ot estimate the reliability of a system tree. It is proved that the estimators set by approximate Bayes method is efficient in Fisher's sense. Moreover. the lower confidence limit of the reliability of a system tree set by approximate Bayes method, which is efficient in Fisher's sense, is investigated.
