The invention relates to an emergency logistics location-routing method based on alpha-reliable mean-excess regret and belongs to the technical field of emergency facility location and emergency vehicle routing. The actual arrival quantity of material is taken as a decision variable to ensure that the obtained solution is valid in any situation. The trade-off function is introduced to make sensitivity analysis on the total material arrival time and the system cost to help decision makers with different risk preferences to make decisions. Based on the alpha-reliable mean-excess regret theory, the method considers not only the tail risk, but also takes the average value of the total material arrival time and the system cost as the objective function compared with the mean strategy, and the scheme obtained based on the alpha-reliable mean-excess regret theory is excellent in terms of the total material arrival time and the system cost, so that the reliability, timeliness and economy of the scheme can be ensured.
