Sun Bao-min · Jingji wenti · 2012
In the grain demand forecasting process,this paper establish grain demand forecasting index system;from the angles of grain ration,feed grain,seed grain,grain for industrial uses and grain loss realize the grain demand forecasting.In the grain supply forecasting process,use the combination forecast model based on the three exponential smoothing model,grey prediction model and the support vector machine forecasting model,implement the grain supply forecasts.Finally,in the comprehensive analysis of grain supply and demand,confirm the existence of the supply and demand of grain gap.
