Abstract

In order to effectively reduce the psychological pain of the victims under the condition of post- earthquake relief material shortage, firstly, a pain cost function is constructed to describe the psychological pain of the victims, and the average pain cost is used to characterize the timeliness and fairness of relief material allocation.Then, aiming ae the lowest average pain cost of the victims and the lowest cost of emergency logistics, this paper constructs a two-stage multi-objective planning model of emergency material distribution center location and coordinated intermodal transportation of materials, and designs an improved two-population genetic algorithm with phased decoding to solve the problem. Finally, an example analysis is made based on actual situation of emergency materials support after Wenchuan Earthquake. The results show that increasing the number of distribution centers can improve the fairness and timeliness of post- earthquake emergency material allocation and effectively alleviate the psychological trauma of the victims; under the premise of determining the number of distribution centers, improving the fairness and timeliness of emergency material allocation will not have a significant impact on logistics costs. © 2022 China Safety Science Journal.
