Abstract

In order to effectively carry out the emergency materials distribution work, a rapid location selection model of emergency materials distribution center to minimize delivery time and cost while maximizing the fairness of material distribution was built in consideration of road damage and recovery after disaster, the dynamic demand of different types of materials and multiple optimization objectives of emergency logistics. Then the hierarchical sequence method coupled with Dijstra algorithm was designed to solve the model, and through data simulation, the rapid location selection model with multi-material and multi-cycle was designed. The results show that the model can not only realize the rapid location selection of the emergency materials distribution center coupled with distribution path under the changes of dynamic materials demand and road conditions, but also reduce the waste of resources, so that the whole emergency logistics system is more agile and more reliable. © 2019 China Safety Science Journal
