What’s Systems Science

New Frontier in Informatics and Systems

Informatics and Systems image

Research and education in the Department of Systems Science deals with a new and unified approach to varied technological problems from the standpoint of systems science. In particular, the approach requires the study of complex systems in the light of self-regulation, self-organization, and self-production. This is closely related to the need for study of the rapid growth in intelligent systems, and also in global systems such as world-wide computer networks. Emphasis is also placed upon the understanding of complicated mutual interactions, hierarchical systems, distributed or parallel self-determination, human-machine interfaces, biomedical engineering, and medical information systems.

The Department supplies a variety of programs for solving pertinent system problems: the analysis, design, control of systems, decision making and simulation algorithms and techniques, as well as their bases in applied mathematics, application software, and hardware. The Department has three regular divisions and one cooperative division. Each division consists of a few chairs. Thirty graduate students are admitted into the Master's program, and 13 into the Doctoral program.

Information System Used in Medical Science and Treatment

MATSUDA Tetsuya, Department of Systems Science

In the modern world, information communications technology is applied to various fields and the medical field is not an exception among them. Hospital information systems such as electronic medical records, diagnostic systems such as medical images, and treatment assistance systems such as surgical robots are used in hospitals. In this way, information communications systems have become an indispensable part of modern medicine. Information technology also contributes to numerous aspects of progress in basic medical research that aims to understand various physiological and pathological conditions by investigating the human body and its cells or molecules.

Our Biomedical Engineering Laboratory in the Department of Systems Science directs applied research that is directly associated with medical treatment by way of developing medical education assisting systems and medical imaging devices and basic research called systems biology that attempts to understand the biological phenomena by considering the body as a system. A diverse range of studies based on the keywords “medical science”and“information science” is conducted in our laboratory by introducing cutting-edge information technology and theories into these fields.

To satisfy your intellectual interests through research at our laboratory, we welcome anyone who is interested in state-of-the-art information systems that contribute to the fields of medicine, medical treatment, and biology.

Systems Science is Interesting!

TANAKA Toshiyuki, Department of Systems Science

"Systems Science" is a very interesting academic field. There is no clear definition, but I believe that the quintessence of systems science lies in our "attitude" toward perceiving and analyzing the intrinsic structure of matters as well as solving problems.

Our study subjects range over a wide variety of problems. For instance, our laboratory conducts research into the theoretical performance analysis of wireless communication systems as well as the mining (structure extraction) of WWW online store data. However, all our research is founded on "machine learning"ムnamely, imparting artificial systems with the functionality to learn, infer, and adapt. This demonstrates that problems which appear completely different may often share an essential structure. The best part of systems science is that it will vastly widen your perspective by enabling you to recognize these facts, and this is what makes it so interesting.

Addressing a diverse range of issues requires not only basic academic knowledge, but also "instinct" for accurately grasping the essence of a problem. The "instinct" you will acquire by tackling specific issues individually will no doubt help you greatly when you go out into the world. Acquiring a balance of knowledge and "instinct," and broadening your outlook on the basis of it. If you find such an approach to pursuing problems interesting, you are welcome at the Department of Systems Science.
