On the basis of the system approach and port economics，an analyzing framework is constructed for port complex systems． This novel framework not only provides an effective way to recognize port systems from different perspectives，but also makes a great contribution to new methodologies for analyzing port systems in new environments with uncertainty and complexity． Secondly，based on the proposed integrated systematic analysis methodology，an integrated forecasting model based on the TEI@ I methodology is proposed for port logistics prediction． In our empirical studies，container throughout series of Hong Kong port is predicted． Empirical results reveal that TEI@ I integrated model can significantly improve the prediction performance over single models presented in this study． It implies that the proposed integrated forecasting model based on the TEI@ I methodology can be used as a feasible solution to port logistics volume prediction and analysis．
