In this study, the buyback policy for two-echelon supply chain in fuzzy demand environment is studied. The models of centralized decision and buyback policy are built by the method of fuzzy cut sets theory and their optimal policies are also proposed. Finally, an example is given to illustrate and validate the models and conclusions. It is shown that the optimal order quantity of the retailer fluctuates at the center of the fuzzy demand and decreases with the raise of the customer return rate. The optimal fuzzy expected profits for the manufacturer and retailer in supply chain decrease with increasing of the customer return rate.
