Having a Centralized Maintenance Workshop (CMW) allows companies to centralize their resources to assure production equipment availability. The introduction of Circular products and remanufacturing processes helps industry players avoid excessive raw material consumption. In a CMW, the remanufacturing process, besides repairing and purchasing new components, recovers a portion of parts that are not repairable. This paper proposes a closed-loop model considering the lifetime of components, which well represents the real-life components' flow through the CMW. Adding the remanufacturing process to the system has some impacts on the performance of the CMW. Main indicators like the waiting time of equipment in CMW and maintenance cost must be studied to be able to evaluate the performances. To this purpose, a new CMW organization is proposed based on a real case in the automotive industry. Considering different possible simulation scenarios is crucial to get reliable results from the proposed closed-loop queuing network model. Several simulations are conducted to evaluate the CMW performance and find the optimal combinations of decision variables.
