对提高灰色预测模型精度的探讨

Discussion on the Accuracy of Grey Predication Model

应用灰色系统理论,以松嫩平原海伦市粮豆薯产量为例,为提高GM（1,1）模型的精度进行了探讨。认为提高对该模型函数残差的辨识水平,是提高模型精度的有效途径。

Applying grey system theory and taking the production of grains, beans and potato in Hailun city of Song-Nen Plain as an example, the discussion on heightening the accuraey of GM(1, 1) model has been conducted in this paper. The author proposed that enhancion the discrimination for the model's functional quantities is an effective approch for increasing the accuracy of model.
