Guangzhou Port Throughput Prediction Based on Grey Metabolism Model and GM (1,1) Model

Abstract

As the cargo throughput of Guangzhou port keeps increasing in recent years, the metabolic model was used to accurately forecast the port capacity data in the next few years, and the forecast results were compared with the forecast results of the GM (1,1) model. It was found that the metabolic model can achieve higher forecast accuracy. The metabolic model was also selected to forecast the cargo throughput of Guangzhou port from 2021 to 2025. The study is intended to accurately predict the data.
