Smoothing device, smoothing system, and computer program product

A computer program product comprising a computer-readable medium containing a smoothing program executed by a computer, the program causing the computer to execute:

• predicting a calculation load of operation at a first time slot on the basis of weather prediction information of a plurality of operation areas in which facility devices that perform environmental control according to control values resulting from the operation based on weather information are installed;
• calculating a calculation load of operation at a second time slot earlier than the first time slot on the basis of the weather information of the operation areas;
• and
• controlling an executing device that executes the operation so that part of the operation to be executed at the first time slot is executed at the second time slot when the calculation load at the second time slot is smaller than a predetermined first threshold and the calculation load at the first time slot is equal to or larger than the first threshold.

A smoothing system comprising:

• a smoothing device;
• an executing device connected to the smoothing device;
• and
• facility devices connected to the executing device, wherein
• the smoothing device includes
• a predicting unit configured to predict a calculation load of operation at a first time slot on the basis of weather prediction information of a plurality of operation areas in which the facility devices that perform environmental control according to control values resulting from the operation based on weather information are installed;
• a calculating unit configured to calculate a calculation load of operation at a second time slot earlier than the first time slot on the basis of the weather information of the operation areas;
• a checking unit configured to determine whether or not the calculation load at the second time slot is smaller than a predetermined first threshold and determine whether or not the calculation load at the first time slot is equal to or larger than the first threshold;
• a deciding unit configured to determine part of the operation to be executed at the first time slot as first operation to be executed at the second time slot when the calculation load at the second time slot is smaller than the first threshold and the calculation load at the first time slot is equal to or larger than the first threshold;
• and
• a first transmitting unit configured to transmit, at the second time slot, second information containing weather information at the second time slot and first information containing weather prediction information at the first time slot to the executing device that executes the operation,
• the executing device includes
• a receiving unit configured to receive the first information and the second information;
• a calculating unit configured to execute the operation on the basis of the first information and the second information to calculate the control values to be used at the facility devices installed in the operation areas;
• and
• an output unit configured to output the control values to associated facility devices installed in the operation areas, and
• the facility devices control environment of the operation areas in which the facility devices are installed according to the control values.
