灰色GM(1.1)模型在钢产量预报中的应用

Application of Grey Mode GM (1.1) in Prediction of Crude Steel Out-Put

    摘要
  • 摘要: 应用灰色系统理论,建立了灰色GM(1·1)预报钢产量的数学模型。该模型可对钢产量进行定量和定性预报。定量预报的平均精度为97.08%(最高精度达99.60%),定性预报结果与实际情况相吻合。

     

    Abstract: A method for output of crude steel prediction using grey system theory is described. This prediction model consists of ration and qualitative anlysis. The qualitative prediction is 97.08% in an average of exact percentage (the most of exact percentage is 99.60%). The ration prediction is the same results with the practical case.
