扩展的SCGM(1,1)_(α0)

An Improvement of SCGM(1,1)_(α0)

对于有明显指数规律但却不能用SCGM(1,1)_(a0)建模的一类数据,本文提出了建立SCGM(1,1)_(a0)的改进方法,扩大了SCGM(1,1)_(a0)适用范围,提高了建模精度,并用该方法预测了邯郸市未来工业用水万元产值取水量。

In this paper,we put forward a improved of SCGM(1,1)a0, for a group of data having obvious exponential law but not being used in SCGM(1,1)a0 The improved method extends the applicable scope of SCGM(1, 1)ao and raises the precision of the model. In the end, we forecast the quantity of industrial water consumption by means of the improved method industrial mater consumption.
