全球镍产品供给与需求的灰色预测方法及其应用

The Model and Applications of Gray Forecasting about the Demand and Supply of Global Nickel Products

建立了全球镍产品供给与需求的GM(1,1)灰色预测模型,并对2010年和2015年全球镍产品供给和需求进行了预测。经精度检验,该模型精度高,为准确预测全球镍产品供给与需求提供了一种可行的方法。

This paper establishes the GM （ 1.1 ） grey prediction model to make a forecasting the demand and supply of global Nickel products, and forecasts the demand and supply of global Nickel products in 2010 and 2015, and points out that the precision degree of this model is high according to the accuracy checking, providing a feasible method for forecasting accurately the demand and supply of global Nickel products.
