Bridging Knowledge Graphs and System Models for Self-Adaptative Digital Twins

Synchronization between the Digital Twin and the twinned system is at the core of Digital Twins systems. In this talk we discuss autonomous synchronization, i.e., self-adaptation, with respect to structure: How to react to changes in the structure of the twinned systems, such as addition or removal of components, which may be a complex operation in presence of long-running operations. In particular, we show how knowledge graphs can act as a unifying layer for the Digital Twin and the twinned system structures. Using this layer, the Digital Twin can synchronize its own structure with a structural model, e.g., SysML or IMF, that describes the twinned system. We give an illustration of this idea using the Oslofjord Digital Twin.
