Container trucks are main energy-consuming equipment in port area of container terminals.The carbon emission from container trucks is especially serious when two very large container ships are stevedoring simultaneously.Therefore,we build a micro-simulation model of container terminal operations by agent-based simulation and microscopic traffic simulation to explore the modes of container trucks scheduling on ship turnaround time at port and carbon emission by trucks in this case.According to the characteristics of truck scheduling mode,we build a micro-simulation model of container terminal operations by agent-based simulation technology and make a quantitative analysis to explore the effect of container truck scheduling modes (including tandem model of loading after unloading for each ship,dual-cycling model of loading and unloading between two ships,and dual-cycling mode of loading and unloading within same bay) and number of trucks on ship turnaround time at port and carbon emission.The example shows that the dual cycling mode can effectively reduce the carbon emission while ensuring the handling efficiency,and the number of container truck only affects the carbon emission generated by idling truck.
