Reusing Model Validation Methods for the Continuous Validation of Digital Twins of Cyber-Physical Systems
Joost Mertens, Joachim Denil
One of the challenges in twinned systems is ensuring the digital twin remains a valid representation of the system it twins. Depending on the type of twinning occurring, it is eith…
DarTwin made precise by SysMLv2 -- An Experiment
Ãystein Haugen, Stefan Klikovits, Martin Arthur Andersen +4
The new SysMLv2 adds mechanisms for the built-in specification of domain-specific concepts and language extensions. This feature promises to facilitate the creation of Domain-Speci…
Decision Oriented Technique (DOTechnique): Finding Model Validity Through Decision-Maker Context
Raheleh Biglari, Joachim Denil
Model validity is as critical as the model itself, especially when guiding decision-making processes. Traditional approaches often rely on predefined validity frames, which may not…
Lab-Scale Gantry Crane Digital Twin Exemplar
Joost Mertens, Joachim Denil
The research topic of digital twins has attracted a large amount of interest over the past decade. However, publicly available exemplars remain scarce. In the interest of open and…
Continuous Evolution of Digital Twins using the DarTwin Notation
Joost Mertens, Stefan Klikovits, Francis Bordeleau +2
Despite best efforts, various challenges remain in the creation and maintenance processes of digital twins (DTs). One of those primary challenges is the constant, continuous and om…
