After the emergency service system, the information management system and decision support system are composed of five subsystems. At the same time, the emergency logistics system will supplement and maintain the position of consumption of materials according to the existing problems in the supply of disaster relief materials, evaluate the materials, ensure the implementation of the work, and adjust the relevant links of the original emergency logistics. From the above analysis, we can see that the emergency logistics system is an important part of the emergency management system, which provides material support for emergency response. Therefore, whether the emergency logistics system can deliver the rescue materials to the demand center quickly and accurately will directly affect the effectiveness of the emergency response. Some natural disasters can predict the scale, intensity, season or time of their occurrence, but many sudden natural disasters and public health events, such as earthquakes, typhoons, floods, mudslides, large-scale food poisoning, coal mine safety accidents, volcanic eruptions, sudden infectious diseases and possible damages, are difficult to predict and predict. Although some disasters can be predicted, due to the short time and time interval of prediction, it is difficult to realize the logistics process under the effect of time and space.
