Digital Twin for production systems: a literature perspective

International audienceDigital Twin is one of the key enabling technologies of the fourth industrial evolution. Alongside with the cyber-physical systems it is expected to widen the perspectives of smart manufacturing development and for production systems in particular. For these systems ongoing state monitoring, simulation and prediction of manufacturing operations are crucial to improve the production efficiency and flexibility. Moreover, through the principles of system engineering, Digital Twin establishes interconnection and interoperability between cyber and physical environments allowing a human to act confidently based on accurately analysed data and verified simulation models. In order to design and implement Digital Twin the architecture and main components must be identified
