| Outline of Final Research Achievements |
We developed a high performance software to simulate the national economy in 1:1-scale and integrated it with a large scale earthquake disaster simulator to comprehensively estimate the long-term economic performance of given recovery plans. Analyzing data from government sources, such as e-Stat, we identified the parameters to simulate the Japanese economy in 1:1 scale; i.e., consisting of 127 million economic entities. Starting with the conditions of 2015, we simulated the Japanese economy until the end of 2019. Good agreement of the simulation results with the observed records demonstrated that the developed model can simulate the Japanese economy to a reasonable degree. We integrated the economic simulator with an earthquake disaster simulator to seamlessly simulate an earthquake disaster in a large urban area, evaluate the degree of the damage, repair cost, recovery period, etc. of each building, and evaluate the long economic performance of potential recovery plans.
