Digital twins

The overall goal of the Aarhus University Centre for Digital Twins is to understand how to leverage existing engineering multi-models for the construction of digital twins.

This entails improving the SoTA in co-simulation algorithms, understanding which multi-models are adequate for digital twin construction, and what kind of faults can be detected/diagnosed.

Attaining this goal implies tackling traditional tradeoffs, such as how detailed we need the co-simulation predicting the behaviour of the digital twin to be, versus how fast? But also new challenges, such as when can one declare that there is a mismatch between the observed behaviour of the original twin, and the simulated behaviour of the digital twin? Can we trust the co-simulation results enough to declare that the original system is faulty when there is a mismatch? What kind of decision support can be provided in analysing the consequences of alternative interventions?
