摘要
应用双向差分方法建立GM(1,1)灰色预测模型,并用于地下水动态预测中。实例应用结果表明,该方法对具有波动性和周期性的地下水动态预测时,比传统的灰色模型更有效。
This paper establishes the GM(1,1) grey forecasting model by use of a two-way difference method.It is applied to groundwater dynamic forecasting.For groundwater dynamic forecasting with characteristics of fluctuation and periodicity,the result shows the model is more effective than the traditional grey one.
