Sustainable relief goods distribution system in large scale disaster - Autonomous distributed system based on the response threshold model for ant colonies -

Abstract

In large scale disasters, many evacuation sites should be set up immediately, and relief goods including foods should be being supplied to every site for a certain period.However, in 2016 Kumamoto earthquake, it is reported that relief supplies concentrated on a few large evacuation sites, and many of supplied foods became spoiled without consuming. However, at other sites, relief supplies were lacking. As this example, in large scale disaster, it is difficult to collect reliable information and to distribute necessary goods to appropriate site in allowable timing. To solve this problem, we employ the response threshold model for ant colonies, and we propose a sustainable relief goods distribution system in large scale disaster. To demonstrate the effectiveness of the proposed system, simulation was conducted.
