Abstract: Aiming at the online prediction problem of the digital twin workshop,an online prediction method of the operation status of digital twin workshop based on real-time data was proposed.The connotation and operating mechanism of the workshop digital twin was analyzed,a simulation prediction framework based on the workshop digital twin was constructed,the simulation operation logic based on the event scheduling method was explained,and the digital twin workshop input characteristics,sample generation,and event processing logic were established.The fusion of real-time data realized the online prediction of the workshop based on continuous transient simulation.An online simulation system for the operating status of the digital twin workshop was designed and developed,and the feasibility and effectiveness of the method were verified through an example.

Key words: digital twin workshop, online prediction, real-time data, continuous transient simulation, event scheduling
