| 摘 要： | DGM模型是在灰色系统理论的基础上,针对于灰色预测GM(1,1)模型的稳定性不足、长期预测时存在较大误差等问题而提出的.通过创建DGM模型,阐述了该模型在进行预测时的条件.并在此基础上对我省的废水排放总量进行了预测分析,研究结果表明我省废水排放总量近些年来呈现快速增长的趋势,必须采取有力的措施加以控制.

| Abstract: | DGM model is proposed based on the grey system theory,which is aiming at overcoming the inefficiency of stability and large error in long-term prediction of the grey prediction GM(1,1) model.The necessary conditions for accurate prediction are illustrated and the total volume of waste water discharge in Henan province is predicted under these conditions.Results show that the total volume of waste water discharge has the trend of rapid growth and some forceful measures must be taken for control. |
