Abstract: The demand of relief drug after a sudden disaster is growing at an explosive rate. Adequate emergency drugs play important roles in mitigating and controlling casualties, guaranteeing relief effect and reducing economic loss. Owing to natural and consumable characteristics of relief drug, our today's nationalpre-positioning model of relief drug is more likely to result in short supply of relief drugs or expired products. It is also hard to guarantee a long-term cooperation relationship between governments and pharmaceutical enterprises. So how to scientifically and reasonably pre-position relief drug is becoming a key problem for governments. This paper introduces an option contract into relief drug management system by considering this system as a relief supply chain. A relief drug pre-positioning(RDP)model is established. The optimal decisions of the government and the enterprise are derived. The conditions that the relief supply chain coordination is achieved and the government and the enterprise will be better off are uncovered. The research shows that the RDP model can improve the total reservation quantity of relief drug, reduce the government's inventory risk, guarantee the enterprise's reasonable profit and control the government's cost. The research findings provide insights into establishing a long-term relationship between two sides and offer important managerial strategies for the government's pre-positioning relief drug.
