Establishment and Implement of Digital Twin Model for an Intelligent Workshop

Abstract

For multi-variety and small batches production, great challenges have been brought to production organization and management of workshops. This paper proposes an establishment and implement framework of digital twin model for intelligent workshops, which mainly consists of four layers. The production behavior and rules of production factors in the workshop are digitally established. Interconnection and communication scheme between each layer are designed and established. At the application level of the digital twin model, the Automated Guided Vehicle (AGV) intelligent scheduling algorithm based on genetic algorithm is combined with Augmented Reality (AR) technology in order to realize visual intelligent scheduling of workshop logistics. And the efficiency of logistics scheduling can be improved. The validity of the proposed framework is verified in an actual production workshop.
