Three kinds of production models of remanufactured products are established based on the price-dependent and quality-dependent demand. The optimal production decisions of the three models are given. The results show that, with the improvement of willing to pay(WTP) for the remanufactured products, the production yield of the new product in second stage of all systems will decrease, and the production yield of the new product in the first stage and remanufactured product in the second stage will increase under Model O and Model OI, and will not change under Model I.With the improvement of quality grade, the production yield of new products and remanufactured products of all systems will decrease. It is also found that with the improvement of product’s quality grade, the original equipment manufacturer(OEM) will lose some profit, the independent remanufacturer(IR)’s profit can be improved in some certain, but the required minimum WTP for its profit will rise. The numerical simulation verifies the effects of the parameters on the production decision and profits.
