序贯顺序统计量可以用来描述系统中组件的有序寿命，其中一个组件的故障可能会影响其余组件的性能。本文考虑了具有这种失效相关元件的系统的剩余寿命和非活动时间的混合表示。获得了不同结构系统的随机比较，并检查了混合表示中的权重的性质。此外，在给定关于先前故障时间的附加信息的情况下，得到了系统剩余寿命和不活动时间的相应表达式。
Sequential order statistics can be used to describe the ordered lifetimes of components in a system, where the failure of a component may affect the performance of remaining components. In this paper mixture representations of the residual lifetime and the inactivity time of systems with such failure-dependent components are considered. Stochastic comparisons of differently structured systems are obtained and properties of the weights in the mixture representations are examined. Furthermore, corresponding representations of the residual lifetime and the inactivity time of a system given the additional information about a previous failure time are derived.
