Application of Grey System Model in Throughput Forecasting of Inland River Port

Based on the practical investigation data of the throughput of Huainan Port,Grey System Theory is selected to research into the throughput forecasting.The result indicates that different grey-system forecasting models shall be selected in different forecasting periods.A combination of GM(1,1) and Verhulst is adopted in short-term forecasting,and Verhulst model,which is revised by GM(1,1)model,is applied in long-term forecasting.The feasibility of the two models is verified through the instance of throughput forecasting of Huainan Port.
