Abstract
In the different stages of emergency rescue, the demand urgency of victims for different types of emergency materials is different. Especially in large-scale emergencies, the transportation resources are limited, so it is more necessary to consider the urgency of different emergency materials demand and give priority to the distribution of materials with high urgency. In this paper, five influencing factors including the degree of irreplaceable, the degree of shortage, the degree of life damage caused by insufficient, the periodicity of demand and the shelf life of demand are determined to measure the demand urgency. The fuzzy comprehensive evaluation method is used to determine the demand urgency value of emergency materials. Emergency materials are divided into three levels: extremely urgent, urgent and general. Simulation results show the feasibility of the method.
