Dynamic Optimization Model and Algorithm Design for Emergency Materials Dispatch

الملخص EN

Emergency materials dispatch (EMD) is a typical dynamic vehicle routing problem (DVRP) and it concentrates on process strategy solving, which is different from the traditional static vehicle routing problem.

Based on the characteristics of emergency materials dispatch, DVRP changed the EMD into a series of static problems in time axis.

A mathematical multiobjective model is established, and the corresponding improved ant colony optimization algorithm is designed to solve the problem.

Finally, a numeric example is provided to demonstrate the validity and feasibility of this proposed model and algorithm.
