在部件壽命服從指數(shù)分布，延遲修理時間和修理時間均服從一般分布的假設(shè)下，研究了修理延遲的部件串聯(lián)的可修系統(tǒng)。利用更新過程理論，得到了系統(tǒng)的可靠度R(t)、可用度A、首次故障前的平均時間MTTFF和(0,t]時間內(nèi)的系統(tǒng)的平均故障次數(shù)M(t)等可靠性指標(biāo)。

Abstract In this paper, a -unit series repairable system with delay repair is studied,assuming that the systematic unit’s life has exponential distribution, the dalay repair time and the repair time both have general distribution,some primary reliabilities indexes are obtained by using renewal process theory, such as reliability R(t), availability A, the mean time to first failure MTTFF and the mean times to failure of the system during (0,t],etc. n
Key words series system; delay; renewal process ; reliability; mean time to first failure
