The remanufacturing system decision model with two competing manufacturers and a communal retailer is established based on the game theory, which considers the impact of quality and price competition on the remanufacturing system. Furthermore, some conclusions are derived based on the equilibrium solutions in the decentralized decision and manufacturers joint decision cases. Finally, some numerical examples are given to analyze the influence of key parameters in the decentralized model on equilibrium solutions and channel member profit of the remanufacturing system, and the impacts to the remanufacturing system when two manufacturers are jointly making decisions are studied.
