Abstract: This paper focuses on the optimal strategies and coordination problems of a supply chain under production cost and market demand disruptions. In view of the different disruption scales of the supply chain under emergencies, the paper discusses the optimal production plan and retail price under centralized-decision model. The results show that the original production plan of the supply chain has certain robustness and it is necessary to change the original production plan to maximize the supply chain profit when the disruptions change greatly enough. For the decentralized-decision model, it is proved that the supply chain cannot be coordinated by the original quantity discount contract, and the new appropriate quantity discount contracts are designed to coordinate the supply chain after disruptions. A numerical example is also presented to illustrate the proposed approach.
