Research Of Selecting Location Of Emergency Rescue Collection And Distribution Centre Algorithm And System Implementataion

China is one of the countries which have the most serious natural disasters. Our natural disasters basically have the following characteristics, such as various, wide geographical distribution, high frequency, great losses and etc. As Chinese national conditions: uneven economic development across the country, many differences between East and West, so much area because of information not accessible result in the increase of disaster loss when disaster strikes. After a natural disaster, find the fastest, the most reasonable way to reduce the loss to a minimum is the core work in the actual process of relief work. Disaster rescue is the most urgent way to reduce the loss of the disaster.Based on the characteristics of the actual relief work and the related study of collection and distribution centre selecting and material dispatching in the past, this paper analyzes the problem of collection and distribution centre selecting and propound models and algorithms with material storage distributing as restriction and without this restriction. The algorithms have been validated to be feasible through the examples of collection and distribution centre selecting. In front of disaster, proceeding from the actual process of disaster relief which considers the needs of materials are various, disaster relief point is more likely multiple, and the time which allows relief material being transported to the area is more important than the cost of transportation. Based on the existing research on the material dispatching, according to the reality of the disaster rescue, this paper propound a model of multi-collection-and-distribution-centre, multi-material, multi-material-storage which aims the shortest time of the transportation. As the same, this model has proved its feasibility. At the end, this paper concludes the lack of the current work, and makes the prospect of future work.
