文摘

In this paper, we develop a joint quality control and preventive maintenance policy for a production system producing conforming and non-conforming units. The considered system consists of one machine which must supply another production line operating on a just-in-time basis. According to the proportion l of non-conforming units observed on each lot and compared to a threshold value l_m, one decides to undertake or not maintenance actions on the system. In order to palliate perturbations caused by the stopping of the machine to undergo preventive maintenance or an overhaul, a buffer stock h is built up from the instant when the rejection rate reaches a threshold level l_A in order to ensure the continuous supply of the subsequent production line. Our objective is to determine simultaneously the optimal rates and , and the optimal size h^* which minimize the expected total cost per time unit including the average costs related to maintenance, quality and inventory.
