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,and one-phase static and two-phase dynamic differential pricing strategies were discussed.In one-phase static optimal decisions,the differential pricing models of various production modes were established to find the corresponding optimal pricing strategies,and the market runs of remanufactured and refurbished products were analyzed.The research results stated that when the manufacturer produced three kinds of products,the remanufactured products would generate the market run of new and refurbished products,while maintain market stability and promote the increase in profits|the refurbished products would not generate market runs for new products,but do it for remanufactured products,while make the whole market growing and profit increasing.During two-phase dynamic pricing decisions,the remanufactured and refurbished products not only generated market runs for the new products of second phase,but also led to the new products sales grow in first phase,and the total profits was increasing with the return rate.

Key words: heterogeneous demands, remanufactured products, refurbished products, differential pricing, market runs
