Abstract: This paper considers a supply chain consisting of a supplier and a retailer. Because of the retailer’s funding constraints or risk aversion, the system cannot achieve the optimal order quantity, so it needs to take some measures to make the enterprises mutually cooperate to achieve coordination of the supply chain. Under a random demand and existing punishment of goods shortage, a model of entirely buy-back is designed to improve the order quantity of the retailer based on trade credit (i.e.suppliers allow retailers to delay payment of the loan). This model makes the supply chain system achieve the optimized profit. And the optimized order quantity and the wholesale price based on the contract is given. Furthermore, a revenue-sharing mechanism based on the model for distributing the profit and improving the operational performance of entire supply chain is analyzed. The parties of supply chain can achieve coordination through the given parameters.

Key words: supply chain, trade credit, buy-back, revenue sharing, coordination
