Digital Twin in Industrial Application – Requirements to a Comprehensive Data Model
form the practical foundation for our pro-
posals. Sections 4 and 5 present our conclu-
sions in terms of the contents and behavior
of digital twin models. These give rise to sug-
gestions about how to realize such digital
twin models, which we present in section 6,
and we conclude with an examination of the
outlook for the future (section 7). the core concept of an “asset” and describes
the following aspects:
D ATA M ODELS FOR D IGITAL T WINS At least one crucial use case for the digital
twin data model mentioned above takes the
form of information exchange between part-
ners in the supply chain, e.g. between “sup-
pliers” and “integrators.”
Probably one of the best-known data models
for digital twins is the “Asset Administration
Shell” as formulated by Plattform Industrie
4.0. In short, this model is structured around
Identification and description of an
