The Emergency Logistics Optimization in Earthquake Relief

The natural disasters, such as Wenchuan large earthquake, are unavoidable and uncertainty. However, the transportation and distribution of the material and substances for disaster mitigation is a critical issue in the first time after the catastrophe coming into truth. This paper discusses the characters of natural disasters and the difficulties faced by disaster relief people in the emergency logistics. Then, formulate an integer programming model in which the materials are divided into two kinds, the common and the reusable, and give the solution method. The research results show that the supply chain of disaster relief should be integrated both in longitudinal and horizontal perspectives so as to realize the effective operation in emergent environment. Meanwhile, the logistics information system linking all relevant databases (stocking units, aid distribution centers, national transportation networks, search and rescue teams, etc.) are also to be built.
