带有残差修正的GIM(1)模型在工业固体废弃物排放量预测中的应用

The Application of GIM(1)Grey Modle with Residuerevision in Forecasting the Industry Solid Waste Amount

基于灰色系统理论，研究和提出了带有残差修正的ＧＩＭ（１）模型，并给出了估计这种模型参数的简捷方法．实例表明，运用该方法得到的模型具有优良的预测精度，从而扩大了灰色预测方法在环境系统中的应用范围．

Based on the grey system theory,a new modle of the GIM(1)with residuerevision is set up and studied in the paper,and a new forthright method of parameters estimation of this grey modle is proposed.A practical example shows that by means of the new method ,the forecasting precision of the GIM(1)modle with residuerevision is fine so that extended the applicable range in grey forecasting method in environmental system.
