Abstract: Aiming at the heterogeneous demands environment with new,remanufactured and refurbished products,the forming conditions and corresponding demand functions of various market situations were analyzed.The differential price model considering retailers engaged in refurbishment with four kinds of production modes were established for the closed-loop supply chain which consisted of an original equipment manufacturer,a retailer and a third party recycler,and the corresponding price strategies were obtained.Under the market situation existing in three kinds of product demand at the same time,the optimal strategies of the retailers and manufacturers respectively engaged in refurbishment were compared,and the conditions for manufacturers selected retailers engaged in refurbishment were analyzed.The research showed that when the retailer was engaged in refurbishment,the remanufacturing and refurbished products would have a market "run effect" for new products and accompanied by "profit occupation" phenomenon.The retailer and the closed-loop supply chain system could reach the highest profit when produced three kinds of products at the same time.Compared with the manufacturer engaged in refurbishment,retailers engaged in refurbishment was in favor of retailers but not manufacturers,but the gross profit of closed-loop supply chain system was relatively higher.Under certain conditions,manufacturers would consider selecting retailers to engage in product renovation to achieve system profit maximization.
