Integrated Model of Preventive Maintenance, Quality Control and Buffer Sizing for Deteriorating Production Systems
In this paper, we develop a joint quality control, preventive maintenance and production policy for a deteriorating system producing conforming and nonconforming units. The considered system consists of one machine which must supply another production line operating on a just-in-time basis. The produced items are periodically subject to a quality control. According to the proportion l of non conforming items observed and compared to a threshold value lm , 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 to ensure the continuous supply of the subsequent production line. A mathematical model is developed in order to determine the optimal rate, lm* of nonconforming units on the basis of which preventive maintenance actions should be started, and the optimal size, h*, of the buffer stock to be built. These values minimize the total expected cost per time unit which includes the average costs related to maintenance, quality and inventory.
