The university library plays the most important role in university. It provides the space and facilities to keep a variety of books and read them. One facility which is the most frequently used in a library is a reading room. In reality, it is the place where many college students spend most of their time. However, there are sometimes severe competitions to get a seat in a reading room, especially near the time of examinations. In order to resolve this situation and to increase the student‘s satisfaction, these days, many universities have installed a seat management system. In this paper, first, problems on the management of a reading room and student’s responses are reviewed. Then operational issues on the seat management systems are investigated and analyzed through simulations. Finally, discussions are followed to improve the effectiveness of a seat management system.
