In order to effectively solve the problem in the decision-making of emergency materials scheduling and transportation,and improve the utilization of emergency materials,the basic procedure,management methods and existing problems of emergency materials scheduling and transportation were introduced.The factors such as dynamic and static resources,disaster distribution,and priority levels of the emergency materials scheduling and transportation system were analyzed,and the synergistic effect among the emergency rescue guarantee departments was studied by referring to the dynamic allocation Multi-Agent method.The supply and demand path and the rescue timeliness of the emergency materials scheduling and transportation system were analyzed,and an efficient,timely and low-cost dynamic scheduling and transportation model of the emergency materials scheduling and transportation system was established.Meanwhile,the solving simulation of the model was carried out based on the multi-source time shortest path problem and the Floyd-Warshall algorithm,then the optimal path of emergency materials and the combination of storage sites participating in the deployment were obtained.The results showed that the dynamic scheduling and transportation decision-making model could quickly search the optimal scheme for emergency materials scheduling and transportation from the candidate set,so as to provide more reliable guarantee for the emergency rescue.
