摘要
考虑外界环境对灰色系统预测模型精确度的影响 ,对GM(1,1)模型进行了改进———用序列算子和影响因子来对原始序列的数据进行一定的处理 ,提高了GM(1,1)模型的精度。通过对我国普通高等学校招生人数及宁夏的农业总产值进行预测 。
Considering the precision inflence to the GM(1,1) model, this paper improves GM(1,1) model by dealing with the original series using the series operator and the influence factor. The rationality of this method is illuminated by the examples which forecast the number of our college's recruit students and the agriculture total production value in Ningxia.
