Abstract
The purpose of this study is to clarify risk perception associated with possibility of human damage of involved stakeholders due to functional impairment of critical infrastructures (FIC) in a seismic disaster. The relation between their personal characteristics and risk perception associated with the possibility of becoming bad health condition due to FIC is modeled as the structure of associated health hazard by analyzing the questionnair suvery data for lay people and by constructing the general multi-dimensional neural network classifier based on a series of Bootstrap simulation. In addition, by applying the classifier to health hazard analyses due to FIC, risk perception associated with its possibility for lay people lived in Japan is revealed representing the format of a hazrd map.
