Revenue sharing contract on the coordination of three-stage closed-loop supply chain under fuzzy demand environment

It tends to produce the double marginalization effectof both forward and reverse direction in closed-loop supply chain,resulting in the supply chain system efficiency losses.In a three-stage closed-loop supply chain composed of a manufacturer,a retailer and a third-part recycler,the coordination mechanism in fuzzy demand environment is researched.The parameters of demand function are considered as triangular fuzzy numbers.The decision processes are analyzed under the decentralized and centralized decision,and the decision model under revenue sharing contract mechanism is built.At last,for direct analysis,a numerical example is given which suggests that the revenue sharing contract can coordinate the profits of members in fuzzy demand environment and make the total profit of supply chain systems reach the level of centralized decision.
