Abstract: The unknownness of the working factor path,the uncertainty of time and the isolation of production factor information in the parts manufacturing workshop seriously affect the effective operation of the shop scheduling.Based on the digital twinning technology,a new method to solve the problem of intelligent manufacturing workshop scheduling was proposed.The framework model and scheduling workflow of the scheduling cloud platform was constructed.Then the whole lifecycle monitoring system of the scheduling cloud platform was built for monitoring the real-time running status of the product.Based on the real-time monitoring data of the whole life cycle monitoring system,the big data analysis technology was used to predict and diagnose the multi-source dynamic disturbance in the workshop production process,on the basis of which the scheduling cloud platform dynamically determined the dynamic disturbance Perturbation strategy.The intelligent manufacturing workshop of an enterprise was taken as an example to verify the application of the dispatching cloud platform model,and the future working direction of the intelligent manufacturing workshop based on digital twins was also pointed out at the same time.

Key words: digital twin, intelligent manufacturing workshop, dynamic disturbance prediction, scheduling cloud platform, full life cycle monitoring system
