Model‐Driven Engineering for Digital Twins: Opportunities and Challenges

Systems Engineering, EarlyView.
ABSTRACT Digital twins are increasingly used across a wide range of industries. Modeling is a key to digital twin development—both when considering the models which a digital twin maintains of its real‐world complement (“models in digital twin”) and when considering models of the digital twin as a complex (software) system itself.
