Closed-loop Supply Chain (CLSC) gives OEM opportunities for remanufacturing, which offers benefits such as reduced production costs and environmental impact. In competitive markets, where Original Equipment Manufacturers (OEMs) and Independent Remanufacturers (IRs) exist, effective pricing strategies are essential to maximize profitability while considering product life cycle time. This study develops a mathematical model to simulate pricing strategies using Salop spatial model as the demand distribution model under three Schemes: (1) OEM exclusively produces new products while IR remanufactures, (2) OEM engages in both new product production and remanufacturing, competing with IR's remanufactured products, and (3) OEM competes with IR in both new and remanufactured product segments. Based on Stackelberg's game theory with the OEM as the leader, the results indicate that the critical influence of product life cycle between short and long life cycle time gives less significant impact on OEM manufacturing decision. Across the three Schemes, Scheme 2 where OEM participation in remanufacturing yields higher profits compared to solely producing new products. The findings also reveal when the reusability rate 𝛽 ≤ 0.35, OEMs tend to adopt a strategy where produce both new and remanufacturing products and sell them in the same market as IRs.
