灰色GM(1.1)模型在鋼產量預報中的應用

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

摘要: 應用灰色系統理論,建立了灰色GM(1·1)預報鋼產量的數學模型。該模型可對鋼產量進行定量和定性預報。定量預報的平均精度為97.08%(最高精度達99.60%),定性預報結果與實際情況相吻合。

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.
