Une politique de maintenance conditionnelle à temps continu pour un système à détérioration graduelle

Abstract : This paper deals with a continuously deteriorating System which is inspected at random times sequentially chosen by a maintenance function. The dégradation is modeled by a Gamma process. Two types of restoration can take place in function of the current System state. The main aim of the paper is to find the optimal maintenance strategy in sensé of the minimum of the long-time average cost engaged by the inspections, the préventive and corrective repairs and breakdowns. A probabilistic study is made on the System évolution process and properties of the cost are derived. We show that a numencal optimization can be performed.
