Demand Stratification and Prediction of Evacuees after Earthquakes

In recent years, frequent natural disasters have brought huge losses to human lives and property, directly affecting social stability economic development. Since the driving factor of disaster management operations is speed, it will face severe challenges tremendous pressure when matching supply emergency resources with demand. However, difficult figure out demands affected area until initial post-disaster assessment completed demand constantly changing. The focus this paper stratify evacuation needs predict number evacuees supplies demanded after an earthquake. This research takes a large-scale earthquake as example analyze characteristics stratification factors that affect evacuees. forecast model for selected improved. Moreover, combining influencing materials evacuees, constructed. proposed used in case Ya’an China estimate daily need supplies.
