Cyber-physical System-based Workshop and a Case Study of Chinese Machinery Manufacturing Company

Oriented by mass customization in recent years, manufacturing enterprises need to transform their traditional workshops to smart workshop. Cyber-physical system (CPS), as a core of industry 4.0, plays an essential role in smart manufacturing. By applying CPS, the traditional workshop will shift into a new paradigm with intelligence and flexibility. However, the implementation of CPS in workshop is a complex task, which is still in its infancy. Thus, this paper presents a comprehensive perspective on CPS-based workshop, which can facilitate the implementation CPS-based workshop in industry. At first, seven features of CPS-based workshop are identified, including self-sensing, self-awareness, self-assessment, self-optimization, self-adjustment, self-configuration, and selfcontrol. Then, the architecture of CPS-based workshop is proposed from technical perspective. Next, a conceptual model of CPS-based workshop is developed, which presents the three fundamental elements and closed-loop mechanism of CPS-based workshop. Finally, a case study of Chinese machinery manufacturing company illustrates the feasibility of implementing CPS-based workshop in industry.
