Abstract: The SEIR model is used to predict the demand for emergency relief materials after the outbreak of a public health event, and the optimization model is constructed with the goal of minimizing the loss of emergency material demand and the shortest total distance of material distribution. In order to ensure the accuracy of the allocation, the model parameters are adjusted according to real-time data every cycle. The scientificity and rationality of the model are verified through the case of emergency material distribution. The results show that this method can effectively solve the problem of emergency material allocation under dynamic demand under major public health incidents, and provides a new idea for solving emergency material allocation under public health emergencies.

Key words: public health event, SEIR infectious disease model, distribution of emergency relief materials, dynamic allocation, Configuration decisions
