This article considers the mean residual life (MRL) function of a coherent system
when the number of failed components of the system is known. We assume that the
lifetimes of the system components are independent and identically distributed (iid)
random variables and show that when the components of the system have increasing
(decreasing) failure rate, that is IFR (DFR), the MRL function of the system is decreasing
(increasing) in time. Same property for k-out-of-n systems with independent
but not identical (inid) components is also shown when the failed components of the
system are known, extending some results in literatures.
