Tetsuya Fujie Laboratory
I received Master of Engineering (Tokyo University of Science) and Doctor of Science (Tokyo Institute of Technology, currently Institute of Science Tokyo).
I worked as an assistant professor in Department of management Science at Kobe University of Commerce, and then an associate professor in School of Management and a professor in Graduate School of Business at University of Hyogo.
I am now a professor in Graduate School of Information Science and School of Social Information Science at University of Hyogo.
【Research Interests】
My research focuses on mathematical optimization in the field of operations research. In particular, I am interested in developing and implementing exact and heuristic solution methods for NP-hard discrete optimization problems such as integer linear programming, integer quadratic programming, routing problems, and scheduling problems. I am also interested in theoretical research behind these methods including polyhedral theory, graph theory, and relaxation methods, and in applying mathematical optimization to practical problems.
My research topics can be summarized as follows:
・Discrete optimization algorithms
・Relaxation and polyhedral methods
・Large-scale optimization and decomposition
・Graph and network optimization
・Scheduling optimization
