Abstract.A maintenance policy for determining the optimal number $(N^*-1)$ of overhauls and the optimal period $(T^*)$ between overhauls which incorporate minimal repair, overhauls, replacement. The cost of minimal repair depends on age and the system is replaced at time $N^*T^*$. It is shown that there exists a unique optimal policy which minimizes the expected cost rate under certain conditions. Various cases are considered.
