Analysis Of Logistics Supply-Demand Network Based On Relief Event

With the frequent occurrence of large-scale disasters around the world since the21st century, the complexity of the relief activities has been increased. Especially in recent years, logistics activities may be inefficient and disordered in front of a large-scale disaster, unable to promote to the effective rescue for life. For this, this paper focuses on how to integrate the limited logistics resources to support the relief activities. Based on the theory of LSSC and logistics network, this paper explores the relief supply-demand network composed of relief logistics service organizations, relief logistics user organizations and the coordinator among them; furthermore analyzes how the coordinator integrates the logistics resources of relief actors and thus reorganizes the supply chain on demand, matching the supply and demand of relief logistics resources.Firstly, this paper introduces the theory relevant to the logistics supply-demand network from different dimensions. Secondly, the paper proposes the relief supply-demand network from three-dimensional space point of view, defines the disaster types and response phase the network serves, and the connotation, elements and features of the network. Then this paper takes the three relief event, refugees in Zaire civil war, Philippines Typhoon Haiyan, Yogyakarta earthquake, as example, to analyze the elements, features and operation of relief logistics supply-demand network. Finally, the paper introduces China’s disaster relief logistics system, and then analyzes the relief logistics operation in Ya’an earthquake, furthermore gives inspiration and reference related to the operation of logistics supply-demand network in China.
