METHOD AND APPARATUS FOR POWER ESTIMATION

摘要

A power estimation method includes acquiring power values consumed by a power estimation target apparatus, each of the power values corresponding to a plurality of parameters; calculating magnitude of variation in the power values in relation to a mean thereof; creating, when the magnitude of variation is less than a first value, a first power prediction formula approximating power consumption of the power estimation target apparatus by a constant which is the mean; calculating a degree of influence of each of the parameters on the power consumption when the magnitude of variation is the first value or more; creating, by reducing the number of the parameters based on the degree of influence, a second power prediction formula approximating the power consumption by a linear equation; and estimating the power consumption using one of the first and the second power prediction formulae.
