Abstract

Consider an n–component coherent system having random lifetime T_X, where X = (X1, . . . ,Xn) is the vector of the non-independent components’ lifetimes. Stochastic comparisons of the residual life of T_X at a fixed time t ≥ 0, conditioned on {TX > t} or on {Xi > t, ∀i = 1, . . . , n}, are investigated. Sufficient conditions on the vector X that imply this comparison in the usual stochastic order are provided, together with sufficient conditions under which the lifetime T_X satisfies the NBU aging property.
