Abstruct This paper censiders an extended cumulative damage model with two kinds of shocks: One is failure shock at which a system fails and the other is darnage shock at which it suffers only darpage. Shocks occur at a nonhomogeneous Peisson process, A system fails when a failure shock occurs or the tetal damage has exceeded a threshold leve] K, A system is also replaced before failure at scheduled time T, Reliability measures of this model are derived, using the theory of cumu]tttive
