Outline of Final Research Achievements

This study developed an analytical method to estimate supply capacity and demand of infrastructure services (water, electricity, and gas) during natural disaster. Survival function type of statistical model is adopted to estimate the duration of infrastructure recovery and. a method for estimating the production capacity loss rate, , which can be applied to evaluate the demand of infrastructure services, are developed. In order to fill in the gap of supply and demand, especially in the case that demand exceeds the supply capacity, this study proposes demand side management strategies such as water harvesting system. In addition, the case of energy shortages in Japan after the 311 earthquake and tsunami disasters is analyzed and derive the resilience characteristics of industrial sectors.
