Welcome to Fujii Laboratory

In our laboratory, we are engaged in research on advanced social simulation to support building social consensus. In particular, we focus on large-scale, complex systems, such as transportation systems and urban systems. Our research encompasses human behavior modeling using artificial intelligence technologies and the development of large-scale simulation systems, with the goal of applying these technologies to real-world analysis, problem-solving, and future system design.
