Dr. Toshiharu Hasegawa, the second president of Kyoto Institute of Information Science and a world authority on operations research, passed away on November 28.He was 77 years old.He has made significant contributions not only in the field of operations research, but also in the fields of systems engineering, communication methods, and road traffic control, and has contributed greatly to the development of education at the University.We extend our deepest condolences.
The wake and funeral were held in secret, with only family members present.
Dr. Toshiharu Hasegawa holds a Bachelor of Engineering degree from Osaka University and a Doctor of Engineering degree from the same university.After serving as a professor of the Faculty of Engineering at Kyoto University, a professor of the Graduate School of Kyoto University, the Director of the Information Processing Education Center of Kyoto University, the Director of the Large Computer Center of Kyoto University, and a professor and the Dean of the Faculty of Mathematics and Informatics at Nanzan University, he became the President of The Kyoto College of Graduate Studies for Informatics in April 2008.During this period, he has also held important positions such as President of the Operations Research Society of Japan, Vice President of the International Federation of Operational Research Societies (IFORS), and President of the Japanese Chapter of the Association for Information Systems (NAIS).
In the field of communications engineering, which was the subject of his early research activities, he was the first in the world to propose a multimedia communication system based on asynchronous time division multiplexing in the early 1960s.After moving to Kyoto University, he expanded his research area to the field of operations research, and was involved not only in theoretical research on queuing, etc., but also in the reality of "road traffic control" as its applied field, and made practical achievements in the areas of new traffic systems and highway control.He also devoted himself to the training of many younger students.
He was a serious and mild-mannered man who was well-liked, and the researchers around him admired him for his foresight in reading the times ahead.We thank you from the bottom of our hearts and pray for his peaceful repose.
