Customs clearance is an essential part of the international intermodal transport system, and the customs passing speed has a significant impact on the transport efficiency of international container. Based on describing the customs clearance process of import legal inspection cargo at Yangshan free port, we established the customs clearance model using Generalized Stochastic Petri Nets and estimated the mean residence time of the cargo with the help of ExSpect. Then, we discussed the modeling and simulation of the improved process based on the proposed optimization measures. By comparing the simulation results, our studies show that the optimum proposals effective.
