Modeling and simulation of full logistics process of the port based on Petri nets

The port is the hinge of sea transportation, and it is also an important target which would be attacked by the both sides in future campaign. At present, most research models on the port capacity are only about the port taken as a berth service organization and the arrival ship as a queuing customer, but few about the full logistics process of the arrival ship loading and unloading cargoes at the port. First, based on Petri nets the model of the port's full logistics process is built; Secondly, full logistics process of the port (commercial port) is taken as a whole study object to be simulated. Finally, the flowchart and simulation conclusion is given.
