摘要
运用灰色系统原理,本文提出了城市用水量测预的非线性灰色模型GM(1,1;(?)_a),相比线性模型GM(1,1)而言,它具有适用性广,拟合精度高等优点。实例验证了该模型用于城市用水量预测的可行性及有效性。
In this paper, a nonlinear grey forecasting model of city water demand GM(1, 1; (?)_α)is presented. The model is based on the principle of grey system. The models applicability and simulated precision gain by comparison GM(1, 1). This model is proved effective by practice.
