研究了组件寿命与冗余寿命存在统计依赖时，相干系统的冗余机制，推导了组件级冗余系统的失真函数，并给出了冗余系统寿命的随机序和失效率序。
Abstract This study deals with redundancy mechanisms of coherent systems with statistically dependent component and redundancy lifetimes. We derive the distortion function of coherent system with a redundancy mechanism at component level, and then we present the usual stochastic order and hazard rate order on redundant system lifetimes. The main results not only enrich the framework of research in this line but also supplement some corresponding results in recent references. Several examples are presented to illustrate the results as well.
