Evacuation and Settlement Model of Personnel in Major Flood Disasters and Its Application

Abstract

In order to select the most suitable rescue boat stop and personnel resettlement point for rapid evacuation and placement of “isolated island” victims. According to the characteristics of “isolated island” problem, considering the factors of total evacuation time and total evacuation cost, a dual-objective emergency evacuation model is constructed. By using the method of fuzzy matrix, the dual-objective problem is transformed into a single-objective problem. Finally, the Hungarian method is used to solve the problem. The results of an example show that the model can realize the selection of the best berth point and personnel placement point.
