20160378128 | DEVICE OPERATION SETTING APPARATUS AND DEVICE OPERATION SETTING VALUE DETERMINATION PROGRAM - A device operation setting apparatus includes a calculator and a determiner. The calculator calculates, based at least in part on a relationship between a setting value regarding operation control of a device and a consumed power of a device, a target value of the consumed power of the device. The determiner determines the setting value to cause that a difference between an actually measured consumed power of the device and the target value of the consumed power of the device calculated by the calculator is within a prescribed range. | 12-29-2016 |
