We consider a supply chain system involved in a perishable product with a fixed lifetime. The retailer is using a periodical reviewed (s, S) policy to manage the inventory and sell the products with backlogs. The supplier and the retailer coordinate the system using a revenue-sharing contract in order to improve the channel performance and maximize the total profit of the system. We show that coordination between supplier and retailer with revenue-sharing contract is possible to improve the performance of the system. Considering the risk of product expiration, the optimal coordination contract is different for system selling perishable product compared with normal long lifetime product.
