Abstract: Although the timetable scheduling system used by some academic departments are computerized, outputs of the systems may still contain errors or conflicting information. Very often, such timetable scheduling systems accepts manual scheduling of the activities. Probably, timetable planning experts may not applying rules, they rely on intuition and holistic reasoning by analogy with previous similar situations. So all these biases of expert judgment, accidental slips of memory, and errors of missing knowledge are the primary problems that might result the bad quality outputs. Sometimes, the outcome of the timetable is workable, but it may not be always desirable, such as there are preferences of lecturers, or convenience of the teaching venue when changing lectures may not be considered. A critic can recognize biases and help to identify and report judgment errors. Therefore, there is a desire to exploit new opportunities for an expert critiquing system to provide user the feedback, criticism or explanation to timetable outputs of the existing timetable scheduling system. The aims and objectives of this dissertation is to apply the expert critiquing theory to develop an intelligent rule-based expert critiquing system for a university timetable system. This scheduling system is intended to assist the administrative staff in producing a better teaching schedules for the academic department according to the subjects' requirements and staff teaching assignments. With the limited research and development time, the project student is using the prototyping approach to develop a preliminary model of this expert critiquing system. Although this is a prototype, its problem domain and scope are sufficient to demonstrate the application of expert critiquing theory. After the launch of the prototype, a small survey on the feedback of user satisfaction to the system has done. Valuable feedback and comments from users has obtained to fine tune the prototype. It is quite encouraging that this critiquing prototype helps the timetable planner in making better quality decision with lesser cost. It also improves the efficiency of producing academic timetable in such a way that academic staff can gain more time to spend on a higher level work.
