Programming model of emergency scheduling with combined air–ground transportation

Abstract

With the effects of dynamic, multi-source, and uncertain features of disaster situations and information on the demand of supplies taken into consideration, this article establishes a scheduling model of a dynamic road network under road network damage conditions according to the min–max principle to make the entire ground scheduling process resemble an actual rescue scene. A scheduling model with collaborative air–ground transportation is proposed with the transport time, transportation cost, and utilization rate of the rescue aircraft taken into account. Results indicate that the model is feasible and effective under different damage degrees of road networks. An analysis of a comparative example among air transportation, road transportation, and combined air–ground transportation, shows that the combined air–ground transportation scheduling model could improve transportation efficiency and guarantee the timeliness and accuracy of rescue scheduling.
