Abstract: This paper addresses a short-ife supply chain which consists of one supplier and one retailer and in which the supplier manages the inventory. It is shown that incentive conflict and double marginal effect still exist in Vender Manage Inventory (VMI) mode. That is,the inventory stocked by the supplier under decentralized decision is less than that in centralized decision. A coordinated contract-unsold recoup contract in which the retailer recoups the unsold inventory,is proposed. Then the impact of disruption, which changes the supplier's production cost (including procurement,transportation cost etc.),on supply chain is studied. A robust contract,which has anti-disruption ability,is proposed. Numerical experimenu are done to illustrate the value of the contract.

Key words: Vender Manage Inventory(VMI), disruption management, supply chain, coordination mechanism
