Optimal Maintenance Policy for a System Suffered Damage in Discrete Time Process

AbstractConsider a system that should be continuously operating over an indefinitely long operation cycle n (…=,2,1n), where each operation causes a random amount of damage to the system, and these damages are accumulated with the current damage. The system fails when the total damage exceeds failure level ζ and a corrective maintenance (CM) is immediately conducted. To prevent such a failure, a preventive maintenance (PM) action should be performed. This paper considers a maintenance policy for such a system, in which the PM is carried out when the accumulated damage exceeds a pre-specified level δ (
