Optimal Preventive Maintenance Policies for a System Suffered Damage in Discrete Time Process
Consider a system that should be operating at the time over an indefinitely long operation cycle.Each operation causes a random amount of damage to the system,and these damages are accumulated to the current damage to the system. A system fails when the total damage exceeds a failure level, and then a corrective maintenance (CM) should be made.To prevent such a failure,a preventive maintenance (PM) should be carried out.In addition,a regular maintenance (RM) action should be performed at every completion of operation cycle in order to maintain the system for the next operation.Two PM policies for such a system,one is operational numberdependent and the other is damage-dependent,are proposed and investigated as well as compared.The expected cost rate for an infinite time span is applied as a criterion of optimality. The optimal policies which minimize the cost rates are derived analytically and computed numerically,and useful properties and discussions for the results are presented.
