Abstract

PURPOSE: To make accurate the demand estimation, by dynamic estimation method taking into consideration past factors.
CONSTITUTION: Taking the matrix representing the time series and demand variation factor to the demand estimation value Y per one day as vector X and model function as f, Y=f(vector X) gives the demand estimation value. In this case, X= (A+X*). The matrix A represents the demand variation factors as time series and the matrix X* indicates the time series change of demand changing factors. When weather is considered as X, vector X1=(weather in the morning)T,... vector X5= (average temperature)T... are considered, and the difference between the day and previous day is considered as X×. As a result, since estimation for water demand of that day depending on the previous day fine or rain can effectively be reflected on the model, the accuracy of sestimation can be increased.
