Digital twin workshop: a new paradigm for future workshop

Abstract

With the integration and extensive applications for new generation of information technologies (such as cloud computing, internet of things, big data, mobile internet, artificial intelligence) in manufacturing industry, a number of countries had put forward their national advanced manufacturing development strategies, such as Industry 4.0 in Germany, Industrial Internet and manufacturing system based on Cyber-Physical Systems (CPS) in USA, as well as Made in China 2025 and Internet Plus Manufacturing in China. Although each of these strategies was proposed under different circumstances, one of the common purposes of these strategies was to achieve the interconnection, interoperability between physical world and the information world of manufacturing and the intelligent operation of manufacturing. As one of bottlenecks to achieve this purpose, the communication and interaction between the physical world and the information world of manufacturing must be solved. To solve the problem, a novel concept of Digital Twin Workshop (DTW) based on digital twin was proposed. Complementary to the concept, the characteristics, architecture, system composition, operating mechanism and enabling key technologies were also elaborated and discussed respectively. On this basis, the theory and implementation of the communication and interaction between physical and information world of workshop based on workshop digital twin data were discussed.
