چکیده
|
We consider a (n - κ + 1)-out-of-n system with exchangeable lifetimes of the components. the paper investigates the stochastic ordering properties of the residual lifetime of the system under condition that,at time t,at least (n - r + 1) components are alive. some results are then extended to the case where the system has a coherent structure with exchangeable components.
