Outline of Final Research Achievements

The numerous major earthquakes in Japan, such as the Great Hanshin-Awaji earthquake, Tohoku Regional Pacific Coast earthquake caused substantial casualties and property damages. Private companies/public utility enterprises should provide disaster reduction investment as part of risk management and prepare a strategic Business Continuity Plan.
The significance of the Business Continuity Plan has been increasingly important in the connection of corporate social responsibility. This study focuses on the seismic risk analysis of the existing water supply system. The probable maximum loss index is employed to evaluate the seismic risk. An alternative method is proposed to evaluate Probable Maximum Loss index of the high order water supply network system.
