| 摘 要： | 研究了城市供水过程中,其用水量、水厂供水量与时间、费用、温度间的关系。首先运用了数理统计和回归分析法,结合散点图形,对数据进行了统计分析,建立了城市用水量和城市供水量与时间的基本预测模型。然后利用灰色系统理论,结合影响城市水量的水价、温度等因素的影响,建立了灰色GM(1,1)预测模型,为城市供水系统提供较有力的理论支持。

| Abstract: | The paper studies the relations among water consumption,and time,cost,temperature in the process of urban water supply.The basic forecasting model of the water consumption,quantity of water supply and time is gained by using the mathematical statistics and regression analysis,in which scattering plot is bound and the data are statistically analyzed.Then the grey GM(1,1) forecasting model is gained by using grey system theory,combining the factors of the water price,which influences water supply,and temperature. |

| Keywords: | statistical method data fit grey GM(1 1) forecasting residual analysis |
