组合模型在物流量预测中的应用

The application of combination model in the logistics forecasting

在分析指数拟合、灰色系统模型的平均预测误差的基础上,建立了组合预测模型,并对广州市的物流量进行了预测。结果表明,组合模型的预测结果是最优的。

Based on the analysis of the mean prediction errors of the exponential fitting and gray model, the combination forecasting model is established, and predicts the amount of logistics in Guangzhou. The results show that the prediction of combination model is optimal.
