【Abstract】 Based on the grey forecast theory, this paper discusses a modeling process used in forecasting urban water consumption. This paper forecasts the water consumption of a city with the basic grey model、the residual GM (1,1) model、the improved new information and equal dimensional grey model and combination grey model. The results show that forecasting water consumption with grey theory is simple and practical. The combination grey model greatly enhances the forecasting precision and can be the tool of forecasting the long-medium urban water consumption.更多还原
