ABSTRACT
This paper presents the use of the Multimodel method for the management of digital twins (DT) in Building Information Modeling (BIM)-based virtual labs. The contents of the Multimodel are based on the software tools required for the specific application, whereby the DT is not a monolithic artifact, but a dynamic set of interlinked domain-specific technical models. The links are specified in machine-interpretable formats, such as the Resource Description Framework or the Web Ontology Language and stored in separate link models. Additional semantic information, that is not part of the technical models, can thus be generated by inference mechanisms. This approach enables the automation of complex processes in cyber-physical systems and increases the robustness against human input errors. A prototypical service implementation and evaluation in a bridge monitoring application underpins the feasibility and benefits of the developed concept.
