Mean residual life of coherent systems consisting of multiple types of dependent components
研究了由多种类型相依部件构成的相干系统的平均剩余寿命，基于生存特征获得了广义混合表示，并定义了两种不同条件事件下的平均剩余寿命函数。
Abstract Mean residual life is a useful dynamic characteristic to study reliability of a system. It has been widely considered in the literature not only for single unit systems but also for coherent systems. This article is concerned with the study of mean residual life for a coherent system that consists of multiple types of dependent components. In particular, the survival signature based generalized mixture representation is obtained for the survival function of a coherent system and it is used to evaluate the mean residual life function. Furthermore, two mean residual life functions under different conditional events on components’ lifetimes are also defined and studied.
