چكيده فارسي :
Sequential order statistics can be used to describe the ordered lifetimes of components
of a system when the failure of a component may affect the reliability of the remaining ones.
After a reliability system consisting of n components fails, some of its components may still be
alive. In this paper, we establish some univariate stochastic orderings and aging properties of the
residual lifetimes of the live components in a sequential (n-r+1)-out-of-n system. We also obtain
a characterizing result for the exponential distribution based on uncorrelatedness of the residual
lifetimes of live components. The results established here extend some well-known results in the
literature
