Periodic preventive maintenance policy in finite horizon with an adaptive failure law

Several periodic preventive maintenance (PM) models have been developed in the literature. This paper introduces an adaptive failure law which can vary over time depending on the missions to achieve. From this degradation law, the purpose of this paper is to develop a preventive maintenance policy for finite horizon of time, noted H, based on a set of improvement maintenance actions at fixed interval with renewal at time H. The problem is to determine the number of PM actions which must be performed using cost criteria. Moreover, the cost and the preventive maintenance duration depend on a coefficient of quality. Numerical example is presented to illustrate this policy.
