With the application and improvement of computer simulation technology and discrete event simulation system. The computer simulation of container terminal loading and unloading process is widely applied. However, on container terminal logistics system are more based on twodimensional system, and the process is observed in direct way. Taking Fujian Port as an example, this paper researches Fujian Port’s throughput, and analyzes loading and unloading process of container terminals, and constructs the data model based on discrete event simulation system. Finally, this paper develops threedimensional process of container terminal loading and unloading with data modeling by data analysis software Flexesmi.
