Comparison of Forecasting Methods for Freight Volume of Inland Navigation and Hydropower Project Post-Evaluation
Sheng Song-tao, Feilian Zhang · 2010
In this paper, for the requirements of freight volume forecast on the Post-evaluation work of Inland Navigation and Hydropower Project, the two prediction methods-exponential smoothing method and the gray method were compared in this article, and established prediction model of each method. By freight volume forecast of DaYuanDu Navigation and Hydropower Project hinterland, the results shows that the gray prediction method forecasting accuracy is higher than that of exponential smoothing method. The gray prediction method is recommended in Post-evaluation work to predict similar data.
