Abstract: Based on buy-back contract,the coordination of a retailer-dominant three-level supply chain system consisted of one manufacturer,one distributor and one retailer was analyzed under the disruption demand situation.The conditions of complete coordination for the three-level supply chain system were derived.The buy-back contract with anti-disruption ability was redesigned to cope with the disruption demand.A numerical example was presented to demonstrate the effectiveness of the model.The results showed that under decentralized decision-making,optimal profit for centralized decision-making could be realized by buy-back contract only on the condition that retailer,manufacturer and distributor's profit function was the affine function of the supply chain system's total profit function respectively.The optimal order quantity function of the supply chain system under disruption demand was determined,and the perfect coordination of supply chain system under disruption demand situation could be achieved by the redesigned buy-back contract with anti-disruption ability.
