讨论了寿命服从极值分布,修理时间服从对数正态分布情况下,可修系统稳态可用度的广义置信下限.特别是针对极值分布的方差未知的情况,用分组求解法获得了广义P值统计量.
Generalized lower confidence limit of steady state availability of the repairable system was studied, which was under Minimum operating time and lognormal repair time. When the variance of minimum distribution is unknown, the generalized p-value statistics is obtained by the grouping method.
