A scheduling system 1 comprises: a storage device 13 that stores evaluation index improvement level information 320 in which is stored the relationship between changes in various elements of an operation schedule and changes in various aspects of the quality of the operation schedule resulting from changes in said elements; and a computation device 11 that executes, based on the evaluation index improvement level information, a changed schedule element selection process for selecting an element of the operation schedule which will most improve the quality of the operation schedule, that executes an optimization model selection process for selecting, from among a plurality of scheduling models by which the operation schedule can be created, the scheduling model in which the quality of the operation schedule as a whole will be most improved by a change in the selected element, and that executes, based on the selected scheduling model, a schedule optimization process for creating a new operation schedule.
