灰色模型在高炉铁水[Si]预测中的应用

Grey model application in forecasting[Si] of hot metal in blast furnace

应用灰色系统GM(1,N)模型对高炉生产生铁中[Si]值进行预报,以等维新息建模方式,反映高炉炉况最新信息;同时结合GM(1,1)残差模型对预测值进行修正,以提高预测精度,运用该方法取得了较好的效果.

Applying a GM(1,N) grey model,the[Si] content of hot metal in blast furnace is predicted,and the latest status of blast furnace is forecast by the equal-dimension and new-information model.To improve the prediction precision,the GM(1,1) residual model was used to modify the forecast results,which arrives at a good effect.
