Modeling of manufacturing systems and analysis of their performances

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. In this paper, we develop a hierarchical modeling for manufacturing system. Based on the IEC 62264 Standard and ISO 22400 Standard. During the developing we also refer to some existing models such as RAMI4.0. And we introduce a practical production line including two computer numerical control (CNC) machines. On which we apply the hierarchical modeling and test the performance of it.
