Stochastic Comparisons of (n − k + 1)-out-of-n Systems with exchangeable components Based on Residual Lifetimes

In this paper, we consider a (n − k + 1)-out-of-n system in which the component lifetimes are exchangeable random variables. In following, we stochastically compare the residual lifetimes of (n − k + 1)-out-of-n systems in one sample and two samples.
