Under the tendency of Industry 4.0, the Cyber-Physical System (CPS) is used to digitize and intelligent the supply, manufacturing and sales information in production, and finally realize fast, effective and personalized product supply. And the concept of ‘Digital Factory’, ‘Digital Production’ and ‘Digital Logistics’ were introduced. With the help of continuous development of automatic control and advanced sensor technology, Intelligent Manufacturing could be achieved. For this purpose, the modeling of the production line can be a good method for describing how the ‘Digital Factory’ works, as well as an achievable method for analyzing the performance of a production line under construction.
