PROBLEM TO BE SOLVED: To provide a technology for correcting a schedule to reduce an influence given by a change in the time zone of a certain manufacturing process to the other manufacturing process as much as possible in the case of correcting a schedule.SOLUTION: In a schedule creation device, a chart image in which predetermined images each showing a time zone when each manufacturing process of a product to be produced by a plurality of manufacturing processes is processed are assigned to time axes is displayed, and a time interval which can be set between the manufacturing processes is stored for each manufacturing process as a constraint related to a time between the manufacturing processes, and a changed manufacturing process as a manufacturing process the start time or end time of whose processing has been changed by changing the predetermined images and the changed time are acquired, and a marginal time between the manufacturing processes is calculated on the basis of the time interval between the manufacturing processes and the constraint of the manufacturing processes, and the manufacturing processes ranging from the manufacturing process closer to the changed manufacturing process among the manufacturing processes with the maximum marginal time to the changed manufacturing process are selected as the manufacturing processes which move in accordance with the changed manufacturing process, and allowed to move. |
