Claim One:
1. An apparatus for estimating water demand, the apparatus comprising: an estimation unit configured to obtain a preset value input by a user; a control unit configured to: obtain record data in response to a user request; set a limit value range of the obtained record data having an upper limit and a lower limit; compare a value of the obtained record data with the upper limit and lower limit in order to extract normal data from the obtained record data within the set limit value range; set the extracted normal data as water demand estimation data; perform a learning process on each of a plurality of algorithm combination groups including at least one algorithm in order to select one of the plurality of algorithm combination groups; and calculate water demand estimation data by inputting the obtained record data and preset value to the selected one of the plurality of algorithm combination groups; a storage unit configured to store the obtained record data, the obtained preset value, and the calculated water demand estimation data; and an output unit configured to output the calculated water demand estimation data, wherein the control unit is further configured to: divide the obtained record data into a plurality of periods; estimate water demand of each of the plurality of periods; and estimate final water demand by combining the estimated water demand of each of the plurality of periods.
