Jointly optimal preventive maintenance under spare parts order strategy

Abstract In this paper, we deal with the problem of preventive maintenance combined with an efficient spare parts strategy. In fact, we established simultaneously the optimal preventive maintenance period and the optimal quantity of spare parts to order for non-self-announcing systems. We considered a manufacturing system of one type of product. The preventive and corrective maintenance actions consist both in replacing the defective part by a new identical one. A mathematical model is developed based on cost criteria and a numerical procedure is used to find the optimal maintenance actions and spare parts quantity to order minimizing operating costs over finite horizon.
