| Abstract: | In view of the limitations in the single forecasting model,the nonlinear combination forecasting model for grain logistics demand was put forward based on the assured grain logistics demand volume.The model was verified using the data of the grain logistics demand volume of Changcbun.The analysis of eroneous results shows that it efficiently improves the precision for the grain logistics demand forecasting. |
