串联系统可靠性严格置信下限的计算 IUMVE法

针对成败型单元串联系统可靠性经典法严格置信限理论迄今存在的困难,我们提出了成败型单元试验结果向量的改进型UMVE(IUMIVE)排序法,在本文中相应提出了IUMVE法求二、三单元串联系统可靠性严格置信下限的算法、程序和部分计算结果,基本上消除了原有四种排序法计算所存在的非正常点。

COMPUTING EXACT LOWER CONFIDENCE LIMITS OF RELIABILITY OF PASS/FAIL TYPE SERIES SYSTEMS BY IMPROVED UMVE ORDERING METHOD

Some unreasonable results of lower confidence limits of the reliability of series systems with binomial components have been produced by all available ordering methods in the classical exact confidence limit theory. To cope with this difficulty, we presented the Improved UMVE (IUMVE) ordering method in 1]. Related with this method, the algorithms and programs for calculating confidence limits of reliability of 2 and 3 binomial component series systems are now presented in this paper. From a large amount of computation, it is shown that the number of unreasonable results of confidence limits is greatly reduced.
