Optimal allocation of convenience facilities to evacuation facilities in a non-aggregated city

Abstract

In the event of a disaster, people evacuate to shelters designated by the local government. The purpose of this study is to investigate the possibility of finding new evacuation spaces by supplementing evacuation facilities and convenience facilities with other functions. 5 allocation methods were used to assign convenience facilities to each accommodation. The results showed that the solution significantly exceeded the maximum travel distance constraint at 1000m. In a non-aggregated area, it is difficult to combine these facilities into an evacuation space due to the fact that they are scattered throughout the area. It is necessary to consider the development of convenient facilities in the vicinity, or to select a location where convenient facilities are close by.
