本文给出了k- of-n系统的剩余寿命的生存函数的混合表示，当组成部分是独立的，但不一定是同分布的。然后，我们随机比较了单样本和双样本问题中k- of-n系统的剩余寿命。特别地，这些结果扩展了Li和Zhao[14]、Khaledi和Shaked[13]、Sadegh[17]、Gurler和Bairamov[7]以及Navarro、Balakrishnan和Samaniego[16]的一些结果。本文还介绍了在比例风险率模型中的应用。
In this article, mixture representations of survival functions of residual lifetimes of k-out-of-n systems are obtained when the components are independent but not necessarily identically distributed. Then we stochastically compare the residual lifetimes of k-out-of-n systems in one- and two-sample problems. In particular, the results extend some results in Li and Zhao [14], Khaledi and Shaked [13], Sadegh [17], Gurler and Bairamov [7] and Navarro, Balakrishnan, and Samaniego [16]. Applications in the proportional hazard rates model are presented as well.
