Résumé

Manufacturing systems are subject to a degradation process that leads to machine failures if no actions are taken. Machine failures decrease the performance of the manufacturing system with loss of profits. The research proposed concerns the evaluation of the manufacturing system performance in dynamic conditions when different maintenance policies are implemented in a multi-machines manufacturing system controlled by Multi Agent Architecture. There are two extreme maintenance policies that can be applied: no preventive maintenance, the actions are taken on failure state; on the other hand an intensive preventive maintenance can eliminate unforeseen failures, but with high costs. Dynamic policy maintenance is proposed to reduce the number of maintenance operations of the preventive policy. A discrete simulation environment has been developed in order to investigate the performance measures and the indexes of maintenance policies costs. The simulations have been conducted for several levels of fluctuation of mix, products' demand and working time uncertain. The simulation results show that the proposed approach leads to better performance for the manufacturing system and reduces the number of maintenance operations (cost index of the maintenance policy), except in case of mean time between failure characterized by very low standard deviation.
