Notes
To impart a common understanding, a DT can include emulation and simulation functions. For instance, the DT in the work of Eckhart and Ekelhart (2018) emulates a real-world counterpart and provides a simulation environment for testing safety and security rules of the real-world counterpart.
Considering that the asset can carry the digital representation of its type, the establishment of suitable reference systems (models) in which important types are described would be beneficial.
