The Application of TOPSIS Method in Selecting Fixed Seismic Shelter for Evacuation in Cities

Selecting appropriate fixed seismic shelters for evacuation is key to earthquake engineering in cities. The author establishes an evaluation system comprising 3 first-level indices and 9 second-level indices related to influential factors such as risk of hazard, location & size and rescue facilities. The indices are generated by use of AHP and entropy methods. Finally, fixed seismic shelters for evacuation are selected by applying TOPSIS method, which proves the applicability of this method.
