指数曲线预测模型在国内铁矿石产量预测中的应用

The Application of Index Curve Prediction Model in Predicting Domestic Iron Ore Output

根据2001～2010年国内铁矿石年产量,通过一阶差分率系数比较方法选择指数曲线模型作为预测模型,并建立指数曲线预测模型得到本年度国内铁矿石产量预测的指数方程,预测出2011年的国内铁矿石大致产量。

Index curve model is chose as prediction model by one --order indifference rate comparison method-according to domes- tic iron ore annual output from 2001 to 2010. The index equation of domestic iron ore production prediction is established and do- mestic iron ore output of 2011 year is predicted by the index curve prediction model.
