In recent years, natural disasters tend to create catastrophic damage because of climate change, abnormal weather, and so on. Therefore, disaster risk analysis and social infrastructure resilience need to be improved. Mitsubishi Heavy Industries, Ltd. aims to contribute to building a safe and secure society by providing customers infrastructure products and services for improved resilience. MHI Research & Innovation Center has its own simulation technologies to predict infrastructure damage and formulate precautionary countermeasures to minimize the damage caused by various types of disasters such as floods, tsunamis, earthquakes, typhoons, fires and leakage/explosions. We are promoting the application of these technologies to actual infrastructures. This report summarizes such analyses and assessment technologies and presents examples of their practical applications.
