Earthquake disaster emergency logistics of transport route optimization research

Abstract

In recent years the earthquake happens frequently, China is one of the countries that suffer the most. The earthquake caused great harm to the national economy and the social development. Under this circumstance, it's necessary to have the research of route optimization in the earthquake.Through the analysis of the actual situation of earthquake disasters, this paper expounds the earthquake disaster emergency logistics of road transportation route choice effects, such as distribution lines, total delivery time, traffic volume, road traffic capacity and its safety factors influencing decision-making, and points out the goal that the earthquake disaster emergency logistics management needs to achieve. Then, the introduction of the minimum time and the maximum flow theory constructs the based model and determining the seismic disaster emergency logistics system highway transportation route choice the basic train of thought to clear the path and freight volume constraint conditions each other, established the earthquake disaster emergency logistics system highway transportation route choice model, and puts forward some solutions to this model algorithm. Finally, through an example, the paper validates the feasibility of the model and the algorithm.
