本文应用预测技术中的指数平滑法，灰色模型预测法对港口吞吐量的预测进行建模分析、验证比较，并提出了修正灰色模型预测吞吐量的方法。通过比较分析．认为改进型灰色模型对吞吐量的预测是一种拟合精度较高，预测较符合实际的方法，适用于港口吞吐量的短期预测。
In this paper, exponential smoothing method and gray model prediction method are used to predict the port throughput, and the methods of gray model prediction and throughput are proposed. Through comparative analysis. It is considered that the prediction of the throughput by the improved gray model is a better fitting method and a more realistic prediction method, which is suitable for the short-term prediction of the port throughput.
