In order to reduce the damage of earthquake, a decision support system based on geographic information system (GIS) for the distribution and transportation of emergency materials after the earthquake is designed and implemented. The allocation and transportation of emergency supplies and transport routes were chosen as the study subjects. The occurrence of an earthquake disaster cannot be prevented. It often results in a large number of casualties, collapsed houses and damaged infrastructure. Therefore, timely assistance is an important measure to avoid further casualties. The results show that the system provides decision makers with a visual aid to the emergency materials distribution plan. Therefore, Matlab software programming can realize the model and its algorithm. The program is compiled into a platform callable file. The two submodule systems of emergency material allocation and transportation and the optimal path of vehicle transportation are combined. The optimization of material allocation model and the distribution system of emergency supplies after the earthquake are of theoretical and practical significance.
