摘要： 为了计算某些特殊工业系统的可靠性,文中提出了寿命可交换的n中取m串连续k失效的系统模型,借助于组合论方法,给出了该系统可靠性的计算公式.进一步,将其应用到载荷分担的系统中.文中提出的系统不要求部件相互独立,从而更有实用性.

关键词: 可交换寿命, 组合论, 载荷分担, 系统可靠度

Abstract: This paper firstly proposes a m-consecutive-k-out-of-n:F system model in order to calculate the reliabilities of some special systems. It also gives a formula to figure out the reliability of the system by aid of the combinatorial method. Further, the model is applied to a system with loads-sharing.

Key words: exchangeable lifetimes, combinatorial theory, loads-sharing, system reliability
