摘要
本文在分析GM(1,1)等维新息模型建模方法的基础上,重点对GM(1,1)等维新息模型的最佳维数区进行了讨论,最后以实例验证了该模型用于预测区域需水量的可行性及有效性。
The paper discusses the optimum new dimension limits of GM(1,1) constant dimension mew information model based on the analysis of GM(1,1) constant dimension new information model establishment method,this model is feasible and effective in the forecast of the regional water demand with the example verification.
