Abstract: A timetable creation apparatus 100 for correcting a target timetable being a train timetable to be used to control a group of trains by using a predicted passenger demand to thereby create a new target timetable, includes: an objective function generation unit 115 that generates an objective function for an operation headway between trains included in the group of trains by using the predicted passenger demand; a constraint condition generation unit 117 that derives constraint conditions which an arrival time and a departure time of each of the trains at each of stations should satisfy for operation of the group of trains; and a candidate timetable creation unit 119 that creates a candidate timetable as an update candidate for a target timetable by using an arrival time and a departure time of each of the trains at each of the stations derived by optimizing the objective function under the constraint conditions.
