(Autiosalo et al., 2020)
(Pedersen et al., 2021)
There is still a need for a common consensus, what makes a digital twin –
and which features it consist of.

Bringing the Digital twin alive
• Lots of work to do• Trust in the models behind
• Predictive maintenance – tools – visualization
• Reactive simple planning tools – what-if analyses
• Assisted supervision
• Dealing with alarms – how to prioritize?
• …
• Supported by a digital ecosystem
