Grey Prediction of Port Throughput Based on GM(1,1,α) Model

According to the situation of lack of statistical data, this paper makes use of the time sequence prediction theory of nonlinear grey GM(1,1,α) Model to predict the port throughput based on the data of LianYungang port throughput from 2003 to 2007, and expounds the application of nonlinear grey forecasting method. Results show that the nonlinear grey GM(1,1,α) model can prediction of adaptability, high precision, simple, and can effectively solve the port throughput prediction problem.
