Abstract

Abstract: In a m-stage reliability growth test, to estimate the lower confidence limit of the reliability of the system in the final stage, randomization is introduced to improve the exsiting natural chain method. Simulation study shows that when the number of stages is one, the randomization method is ideal.

Key words: reliability, lower confidence limit, sample space ordering, ML ordering method, NATURAL dictionary ordering method

摘要： 通过引入随机化方法对处理指数分布定总时有替换可增长型数据的NATURAL字典排序法给予了改进，进而改进了对产品可靠度置信下限的估计。

关键词: 可靠度, 置信下限, 样本空间排序法, ML排序法, NATURAL字典排序法
