Abstract: In the condition of considering the demand belonging to linear function with price, a closed-loop supply chain system with single manufacturer and single retailer was established. When disturbing incident caused disruption of market scale, reproduction cost and recovery price sensitivity coefficient simultaneously, a two-echelon closed-loop supply chain model was constructed. The optimal strategies of closed-loop supply chain under the centralized mode and decentralized mode were studied respectively. Research result showed that the original quantity discount contract of the closed-loop supply chain with no disruption had certain robustness under a small disruption. However, as the disruptions exceeded a certain range especially recovery price sensitivity coefficient when disruption even was happened, the original production plan should be changed and the new quantity discount contract should be designed to coordinate the closed-loop supply chain. A numerical example was given to verify the effectiveness of conclusions.
