AN ANALYSIS OF PUSH-MODE HUMANITARIAN LOGISTIC CHAIN FOR NANKAI TROUGH EARTHQUAKE

Abstract

Feasibility and efficiency are investigated on push-mode relief supplies to the refugees in Nagoya planned by the government at Nankai Trough earthquake. Based on the assumptions on the loading/unloading time, the time needed for delivery of relief supplies is examined considering the usages and the combinations of logistic depots within area (secondary depots). The results suggest that the delivery time can be reduced by aggregating the transport from the primary depots to the secondary depots, and becomes closer to the case skipping the secondary depots. Also, random breakdowns of the road network by the earthquake are represented in the simulation, and it is found that the priority opening of core road network within area can increase the reachability to the refugees.
