Discrete event-driven twin workshop modeling and simulation technology

For the digital transformation and upgrading of the workshop production line, how to improve the digital level of the workshop and the utilization rate of production data is the key to the transformation. Based on digital twin technology, this paper proposes a discrete event-driven digital twin workshop operation framework, and proposes three key technologies for discrete event-driven twin production line simulation operations. These include digital twin workshop modeling technology, multi-event concurrent operation control technology, and event-driven simulation operation technology. Through the above technologies, the display of workshop production status and key production data and the virtual simulation of workshop production process can be realized. Finally, the author establishes a digital twin production line simulation system with an aerospace assembly workshop as the object, and verifies the effectiveness of the technology.
