Description

ABSTRACT:
A demand estimation apparatus for controlling machines according to revised estimated demand values wherein estimated demand values are calculated by dividing demand cycles which are fluctuating similarly cyclically into a plurality of sections (time zones), an adjusting section is interposed between each two sections adjoining each other, and an estimate of the fluctuation of the demand is determined based on measurements of both the demand value of the adjusting section and the demand values of the two adjoining sections, and wherein the estimated demand value of each adjusting section is compared with the estimated demand values of the respective two adjoining sections and, based on the comparison, each adjusting section is moved as a whole toward one of the adjoining sections by a predetermined time width when the estimated demand value of the adjusting section more closely approximates the estimated demand value of that one of the adjoining section than the other adjoining section, thus modifying the time widths of both adjoining sections, and the estimated demand value is revised to account to for fluctuations in the demand within the shifted adjusting section and modified adjoining sections.
