Course timetabling is a well known constraint satisfaction optimization (CSOP) problem, which needs to be solved in educational institutions regularly. Unfortunately, this course timetabling problem is known to be NP-complete [7, 39]. This M.Sc. thesis presents a multi-phase approach to solve the university level course timetabling problem. We decompose the problem into several sub-problems with reduced complexity, which are solved in separate phases. In phase-1a we assign lectures to professors, phase-1b assigns labs and tutorials to academic assistances and graduate assistants. Phase-2 assigns each lecture to one of the two day-sequences (Monday-Wednesday-Friday or Tuesday-Thursday). In Phase-3, lectures of each single day-sequence are then assigned to time-slots. Finally, in phase-4, labs and tutorials are assigned to days and time-slots. This decomposition allows the use of different techniques as appropriate to solve different phases. Currently different phases are solved using constraint programming and integer linear programming. The multi-phase architecture with the graphical user interface allows users to customize constraints as well as to generate new solutions that may incorporate partial solutions from previously generated feasible solutions.
