组合预测模型在货运量预测中的应用

On the Application of Combination Forecasting Model in Freight Forecast

本文对灰色预测模型和ARIMA预测模型进行组合,建立了组合模型,并应用于货运量的预测,实证预测表明,组合模型的预测精度优于单一的预测模型,预测结果与实际货运量拟合较好。

By combining gray forecasting model with ARIMA forecasting model,in this paper,the writer sets up a combined model and applies it in freight forecast.The case forecast proves that the forecast accuracy of combined model is better than the single forecast model and the forecast result is in a good coincidence with the actual fright.
