The proper planning and designing of the harbor channel’s traffic capacity is beneficial to the improvement of the service efficiency and quality of the harbor system. On the basis of the summarization of the factors influencing the harbor channel’s traffic capacity, this paper analyzes the computation model and the simulation model of traffic capacity from such three aspects as the deterministic mathematical analysis, statistical analysis methods based on queuing theory and simulation analysis respectively, the research ideas, the advantages and disadvantages of which are described. The mathematical analysis focuses on the static analysis, while the simulation technique focuses on the dynamic analysis and also can combine various factors that influence the traffic capacity of harbor channel. This overview research may serve as guidance for related further research.
