Study Of Supplies Distribution Model In Relief Logistics

China is a natural disaster-prone country; the annual cost spending on relief logistics is very huge. In the year 2003, "atypical pneumonia" let us understand that it is very urgent and important to improve our disaster and sudden crisis emergency management ability. Thereafter, Chinese government and academia gave high concern and attention to this area. "Emergency logistics" has become a new hot domain of logistics study. As a typic "emergency logistics", "relief logistics" has been studied in this paper.Beginning with the logistics needs for disaster relief, this paper analyzes the status and insufficient of disaster relief logistics in China. Then, this paper gives proposal for relief logistics system-building in our country, by learning from advanced experiences of foreign countries. On this basis, this paper sets up China's relief logistics system from both organizational structure and function aspects.To achieve relief logistics, this paper makes deep research of distributing relief material by using emergency distribution model, including non-capacity constraints and transportation capacity constraints, both for single and multi-material goods. Additionally, it uses computer program to achieve its operations. As a complementarity and extension, the article also discusses muliti-goal and dynamic response of relief logistics, taking into account that disaster causes certain changed in existing logistics system, such as road conditions. Under these circumstances, this article introduces object-oriented model to ensure relief supplies. Currently, China has not yet formed relief logistics system, the study and achievement of this paper will be useful to China's logistics system construction.
