Abstract

This research is conducted for the sake of optimizing multi-modal transport routes of emergency relief materials, highway, railway and airway, so as to transport them to disaster-stricken areas in the shortest time. In light of actual situation of multi-modal transport network, firstly, an optimization model of it under time-varying network was constructed with factors taken into consideration, like variation of transshipment time, time limit of railway dispatch, and prohibition time of flight due to weather conditions. Then, an ant colony algorithm was designed. Finally, a case study was carried out. The results show that this model and algorithm can quickly select a transportation plan that will deliver emergency relief materials to disaster-stricken areas in the shortest possible time according to requirements of decision-makers, thus providing necessary support for them. © 2019 China Safety Science Journal
