Abstract: An timetable plan creation system 100 includes: a storage device 101 that stores information regarding a constraint that is generated in each of timetable variables of an timetable plan and regarding the intensity of the constraint, information that associates a creation algorithm of the timetable plan and a measure of an evaluation index improved by a timetable variables of the timetable plan and by the creation algorithm, and information on desired change of the intensity of the constraint; and a computing device 104 that generates a constraint that has an intensity and that is generated for each of the timetable variables of the timetable plan, and that selects a plan creation algorithm for improving the quality of the timetable plan, and that creates a new timetable plan by executing each of selected plan creation algorithms to which the generated constraint is applied.
