A data center management method executed by a computer that includes a first memory and a second memory, the method includes storing, in the second memory, a predicted value calculated based on measured values obtained as measurement data and differences each corresponding to the measurement data obtained a predetermined period ago; storing, in the first memory, the measurement data as the measured value; calculating, based on each of the stored measured values, an amount of change which is a difference between the measured value and the predicted value, and storing the calculated amount in the second memory; calculating first corrected prediction data based on the measured value currently measured and the measurement values previously measured; calculating second corrected prediction data based on previous amounts of change and the first corrected prediction data; and controlling the device using an operation amount calculated based on the second corrected prediction data.
