An Integrated Digital Twin Simulation and Scheduling System under Cyber-physical Digital Twin Environment

This paper described the research and study of an integrated digital twin simulation and scheduling system under a cyber-physical digital twin environment for manufacturing. The proposed approach provides optimal production schedules based on real-time information from an established cyber-physical digital twin platform. The system can be integrated with existing manufacturing systems, such as ERP, MES, and SCADA systems, via the cyber-physical digital twin platform so that the scheduling results are adaptive to the dynamically changing environment and market demand. The proposed system was designed to leverage the advantages of digital twin simulation, optimization, and scheduling techniques. A prototype was developed to illustrate an application case in the electronics manufacturing industry.
