  • Publication number: 20220414582
    Abstract: A schedule change apparatus includes a change model creation section, a schedule creation section, a schedule change evaluation indicator creation section, a production simulator, and a control section. The change model creation section creates a change model estimating a portion of the schedule to be changed. The schedule creation section uses the schedule change model to generate proposed schedule changes and generate a proposed alternative schedule. The schedule change evaluation section generates a schedule change evaluation indicator indicating a best value for a proposed schedule change. The production simulator implements simulation with a simulation condition changed on a basis of schedule execution status information and equipment operation status information for the day and calculates values of the schedule change evaluation indicator for the proposed alternative schedule candidate group on a basis of the schedule change evaluation indicator already learned.
