 Digital Twin is a new academic field that aims to replicate everything in the real world in the digital space, enabling the prediction of product failures and the optimization of production management through real-time simulation. To realize the Digital Twin, Digital Twin is a new academic field that aims to replicate everything in the real world in the digital space, enabling the prediction of product failures and the optimization of production management through real-time simulation. To realize the Digital Twin,
 various advanced technologies are required, and in our laboratory we are working on the research and development of systems and platforms that integrate high-precision 3D measurement, real-time sensing, highly reliable high-fidelity simulation, industrial big-data analysis, and other necessary elements. various advanced technologies are required, and in our laboratory we are working on the research and development of systems and platforms that integrate high-precision 3D measurement, real-time sensing, highly reliable high-fidelity simulation, industrial big-data analysis, and other necessary elements.

-航空機、列車など安全性と効率性を両立する運行システムを策定するモデルとシミュレーション手法の開発、それを利用して社会の構成要素が互いに影響し合う効果を分析・予測する技術の研究を行っています。計画に基づいて運行（運航）される大規模輸送システムは近年急速に複雑化し、これら社会を支える輸送システムにおける遅延やそれにともなう経済的な損失は近年日常的になっており社会問題となっています。ここでは現在、航空交通システムを主なターゲットにして、スーパーコンピュータも活用しながら急速に複雑化する大量輸送システムの効率化に資することを目指しています。+We are researching the development of models and simulation techniques for designing transportation systems that need to balance safety and efficiency, such as aircraft and trains. We are also developing techniques for analyzing and predicting the effects of different societal components interacting each other using the developed models. In recent years, the complexity of large-scale transportation systems has increased rapidly. Delays in these vital societal transportation systems and the associated economic losses have become commonplace, causing social problems. The current focus is on air transport systems, and we aim to use supercomputers to contribute to the efficiency of these rapidly complex mass transport systems.
