Based on the fractal self-similarity theory, this paper puts forward the service level analysis method of container terminal's logistics system. Based on the detailed study of container terminal's logistics system, firstly, the self-similarity characteristics of container terminal' logistics system are extracted to verify the applicability of fractal theory to container terminal's logistics system. Secondly, the simulation analysis model is established, which measures the service level of container terminal's logistics system from nine indicators, such as annual throughput, average service time of the ships, average ship-time efficiency, average utilization rate of berths, average daily occupancy rate of container yard, etc. The simulation model is applied to a container terminal, and the results show that the model can not only evaluate the overall service level of the container terminal, but also analyze the influence of different storage time and ship inter-arrival time on the service level of the terminal, so as to provide the basis for the terminal operation decision. The constructed model is a useful tool for assessing the validity of ideas about the functional interrelationships between the dry port's primary parameters, as well as the system's long-term viability.
