To analyze the impact of quantitative assessment of LNG ship navigation,this paper uses multi-agent simulation technology to establish a complete set of evaluation indices based on the simulation modeling platform.Taking the LNG project in Jiaxing port for example,the simulation model proposed makes use of the interrelations of agents and characteristics of the real-time interaction to carry out the modular development of elements involved in the port operation system,which can scientifically and effectively simulate the actual operation of the port.Considering the comprehensive analysis of all indices,we draw the conclusion that the LNG ships in Jiaxing Port have limited impact on its port operations.
