Existing researches on the status of port production operations were concentrated on the channel transit capacity on the basis of the vessel traffic flow.However,the actual port production operation should be regarded as a random service system and various random factors of navigable environment should be considered in term of channel transit capacity,and in view of matching with berths and anchorage.By adopting the multi-agent simulation technology and simulation software platform Anylogic,a simulation model for port production operation system,which is a scientific and objective reflection of the actual port production operation,is employed to analyze the logical structure of the entire entry and departure process for vessels and to provide technical support and decision-making basis for the port layout and waterway construction projects.
