Decision-Making Support System for Earthquake Disaster Prevention Countenneasures Based on Seismic Risk Evaluation

Abstract

It is not easy to select the most effective earthquake disaster prevention countenneasures under various conditions,and it has done by a subjective judgement of the person in charge of disaster prevention.It is requested that a new method to assist a local govemment and an enterprise in decision-making should be established.In this research,a decision-making support method using Analytic Hierarchy Process,AHP,is developed,that helps to prioritize earthquake disaster prevention countenneasures based on results of the seismic risk assessment for an area.As a case study the developed method is applied to selecting the most effective countermeasures of aseismic strengthening of school buildings.It is concluded that the present methodology using AHP is effective for a decision-making support.
