PERFORMANCE EVALUATION OF CENTRALIZED MAINTENANCE WORKSHOP IN THE CIRCULAR ECONOMY CONTEXT

Overview & Synopsis

The availability of production equipment is crucial to the life of manufacturers. When these high capital assets are heavy and require a significant set of resources, the company groups all the maintenance activities together in a centralized maintenance workshop (CMW). The circular economy, by integrating remanufacturing, is a way to support industrial development. Once integrated into the maintenance workshops model, the remanufacturing allows the recovery of irreparable components from failed equipment. Thus, the decision regarding the initial stock level and the remanufacturing rate has to be made. This paper proposes a new form of organization of the CMW allowing to take into account the different actions which contribute to sustainable development. Thus, depending on the condition of the defective equipment which can come from various production workshops, three options are available: repair, replacement with new equipment, or reconditioning/remanufacturing. A CMW model based on queuing networks is proposed as well as a simulation evaluation of performance indicators.
