INFLOW FORECASTING SYSTEM, INFLOW FORECASTING METHOD AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To make possible easy forecast about the inflow of water into a water storage facility. PSOLUTION: The information on a weather track record is stored in a database 40 on the weather track record for every date, and the information on weather track record includes the track record value of the inflow, a track record value of a rainfall, and a track record value of snowfall. In the inflow model 1 stored in a model memory unit 31, a rainfall P1SBt/SBand the difference between an inflow FSBt-1/SBand an equilibrium inflow SB1/SBare made description variables, and the amount of an increase FSBt/SBin the inflow is made an objective variable. An inflow model estimate part 23 conducts a regression analysis based on the track record value of the inflow model 1, the track record value of the inflow model 1, and the inflow model 1. Thus, regression coefficients SB1/SB, SB1/SB, and SB2/SBare estimated. An inflow forecast part 26 forecasts the inflow based on the information on the weather track record and the inflow model 1.
