  • Patent number: 9946242
    Abstract: An optimized operation schedule of a control-target apparatus is ensured while maximally reducing a burden share to a facility operator. An energy predictor sets, for a control-target apparatus, a predicted value of energy consumption or energy supply within a predetermined future time period based on process data. A schedule optimizer optimizes an operation schedule of the control-target apparatus within the predetermined time period with a predetermined evaluation barometer based on the predicted value, the characteristic of the control-target apparatus, and the process data. An approval request determiner determines a necessity of an approval for a latest operation schedule based on a preset determining condition. A determination result transmitter transmits a determination result by the approval request determiner.
