Research Abstract

The main theme of this study is the seismic risk management of a lifeline system, which evaluates the seismic risk quantitatively and consider how to decrease the seismic risk. One of the countermeasures against the earthquake is to increase the redundancy of system and thus a redundancy index RE is proposed with information entropy, which can express the redundancy of the system objectively. And the redundancy index RE is applied to the Kobe water distribution network as case studies whose productions are presented on the international conferences and ran in the journals of JSCE and ASCE. And the earthquake insurance is also excellent countermeasure against the earthquake, which can compensate the loss of system with money. Therefore the optimum premium between the insurance company and the user is discussed, whose production is published.
And on the other hand, the basic studies to prefer the optimum countermeasure against the earthquake on the utility function and the recognition degree of citizens on the risk are carried on. And the study of integration for conditional random fields is approached to investigate the performance of system on the earthquake hazard.
For the future study, the Stochastic DCF (Discounted Cash Flow) method, which is able to evaluate the system performance with not only loss of the system against the earthquake but also' asset of the system facilities, is discussed.
