Models Of Scheduling Emergency Materials And The Applications For The Devastating Eartuquake Rescue

Earthquakes are a type of natural disaster that would be harmful to our national security in the aspects of economic development, people’s lives and property, especially the devastating earthquake with a high-level of destruction. Once the earthquake occurs, it will result in horrible loss of innocent people’s lives and loss of property. Because of the special geographical location and specific national conditions, China has become one of the most earthquake-prone countries where devastation could bring an enormous amount of damage. In the light of such high risk of earthquakes, appropriate deployment of emergency materials plays an important role in all aspects of the emergency logistics. To be more specific, the importance of emergency materials is determined by whether they can be sent to the demand points in a timely, accurate, and efficient way. Consequently, the study of the deployment of emergency materials for the rescue of devastating earthquakes has a great significance.First of all, this paper would use the theories of logistics engineering and management operation research, and based on the characteristics of the emergency materials demand and the deployment between devastating earthquakes, aimed at the issue of emergency materials as the research object. Then, depend on the principles of strong time efficiency and weak economic effectiveness, the paper would be considered some problems that the transport capacity constraint of the supply center of emergency materials, the road network connectivity, and the time requirement of deploying emergency materials; and would be aimed on the two types of deploying emergency materials which are "multi-supply points-single demand" and "multi-supply points-multi demand". Then the multi objective model would be built up. Moreover, the paper would study the solving methods about the model to focus on the three problems about deploying emergency materials. The first problem is to find out a great location to set up emergency materials outlets; the second one is to decide out which supply points should deploy emergency materials to which supply points; the third one is to figure out how much the deployment of the material quantity need to be deployed from each supply centers to the single or multi demand points. At last, the paper would be planed to find out several scientific solutions of deploying the emergency materials by using the solving steps from the model, and by adopting the optimization software for example analysis.This paper would mainly contribute to solving complicated problems in case of the deployment of emergency materials. Meanwhile, it also provide relevant decision-making models and algorithms to develop the optimum deployment of emergency materials.
