Digital twin workshop architecture design based on UAF

The digital twin workshop is an important scene of intelligent manufacturing in the future, which improves the production efficiency of the workshop with its advantage of a combination of virtuality and reality. However, there is still a lack of study on the whole life cycle of digital twin workshop production and the interaction mechanism between the various systems in the workshop. In this view, our paper aims at the architecture of the digital twin workshop. Firstly, we reviewed the works in various business fields of digital twin workshops. Then we introduced the connotation of Unified Architecture Framework (UAF) and proposed the ideas and steps of digital twin workshop architecture design. Finally, the multi-view models of the digital twin workshop architecture were constructed from the perspectives of overview, requirement, operation, strategy, personnel, and resources. This work aims to provide theoretical and application support for developing the digital twin workshop.
