GIS-based safe area discovery for emergency logistics

Quick response to urgent relief right after natural disasters through efficient emergency logistics distribution is vital to the alleviation of disaster impact in the affected areas, which remains challenging in the field of logistics and related study areas. This paper analyzes the spatial data and the attribute data by space model and logistics models. Numerical studies with a real large-scale earthquake disaster occurring in Wenchuan are conducted, and the corresponding results indicate the applicability of the proposed method and its potential advantages.
