A decision-making support system for disaster prevention measures based on evaluated earthquake risk

This study proposes a decision-making method, based on the analytic hierarchy process (AHP) approach, to select the optimum earthquake disaster countermeasures using seismic risk assessment. This method uses an evaluation function that transforms the quantitative effect of a countermeasure into its desirability for the decision-maker. This method was used to evaluate plans for strengthening a group of school buildings owned by a local government against earthquakes. It was shown that the method was effective at making a decision for the earthquake disaster prevention measures.
