Abstract: In a supply chain from a supplier to a retailer, the trade credit the former offered to the latter is possible to affect individually their target profit hence the total profit of the supply chain. To solve the problem, the total income from the supply chain should be shared rationally between the supplier and retailer, thus developing a contractual coordination model for quantity discount based on trade credit in random demand. Analyzing the effect of quantity discount policy on income sharing and coordination on the basis of a certain trade credit, the optimal contractual parameters are deduced to realize the coordination of the whole supply chain. A numerical example is given to demonstrate the correctness of the conclusion drawn from the coordination model and relevant analysis.
