Abstract :
Both transfer model and metabolism GM(1, 1) model are usually used to establish dynamic prediction model. This paper applies these two models to Fuzhou port´s throughput prediction and compares the results. The results show that both models can obtain satisfying predicted values. Furthermore, metabolism GM(1, 1) needs fewer data and performs better in terms of prediction accuracy.
