摘要
本文简要介绍了灰色系统的概念,灰色系统中GM(1,1)预测模型及其推导过程,并应用该模型预测了1988年全国钢产量。最后通过几种方法预测结果的比较,证明该模型是一个精确度较高的预测模型。
This paper presents the concept of 'Grey Systems', its forecast model GM(1.1) and deductiveprocedure. By using this model, the paper gives the forecast of the steel output of China in 1988.Finally, it is shown that the model is the only one which could give a figure close to the factafter having compared with the results obtained by several other forecast methods.
