Scenario of the Restoration Process associated with Critical Infrastructure and its Interdependency due to a Seismic Disaster

－A Case Study for the anticipated North Tokyo Bay Earthquake－

Abstract

In this paper, we analyze the scenario of the restoration process associated with critical Infrastructure such as electric power supply, gas supply, water treatments, communication and road networks due to a seismic disasters. The North Tokyo Bay Earthquake is anticipated. First, the restoration process is analyzed by investigating the operational plan for disaster prevention offered by the stakeholders associated with subject critical infrastructure distributed in the Tokyo area and second, the related interdependency is modeled by selecting the dominant events in the restoration process and idealizing them as the network format.
