On Material Dispatch Model and Algorithm in Emergency Supplies Region
【摘要】：正To large-scale emergency material dispatch across regions,the material dispatches in emergency supplies regions]are trie! Key ensuring follow-up materials! of emergency.In Oris paper,hub-and-spokej network is! applied to the dispatch]of emergency supplies in the regions,and,for continuous! consumption problem,a bi-level optimization mathematical model based on both the earliest start time for material outside-transport and the lowest cost is established. Then the algorithm for the model is given.An example for the model is solved finally.
