Abstract: Aiming at the problems of poor timeliness and unpredictability of quality control in the process of complex product assembly,a quality control method based on the digital twin was proposed.A digital twin model of physical workshop,virtual workshop and workshop service system was constructed to control quality,which had realized the collection,analysis and feedback of quality data in assembly process.On this basis,Markov method was used to predict the future state of quality data.The quality control platform of complex product assembly process was built,and the accuracy of the method was verified by an example.This method provided a new way for the quality control of complex product assembly process.

Key words: complex product, assembly, quality control, digital twin technology, Markov method
