Abstract: As one of the important development directions of “Made in China 2025”,remanufacturing plays a huge role in resource recycle,reducing energy consumption and promoting transformation and upgrading of manufacturing.As a new technology,digital twin can fully connect and integrate the physical world and information world in real time,and can effectively promote the integration of informationization and industrialization in the shop-floor.Aiming at the uncertainties in the process of remanufacturing and the situation that information space of virtual remanufacturing and actual remanufacturing process can't be interactively integrated in real time,the digital twin was applied into the remanufacturing operation process,and the architecture for digital twin-based remanufacturing shop-floor was constructed.This architecture and it's operation paradigm were elaborated respectively,the application analyses for key technologies involved was made,and the remanufacturing operation paradigm for automobile based on digital twin in future was also explored.The application prospects for digital twin-based remanufacturing in related fields were discussed.

Key words: digital twin, remanufacturing, virtual remanufacturing, shop-floor architecture, operation paradigm, automobile
