Capturing Autonomy in its Multiple Facets: A Digital Twin Approach

Abstract

Autonomy has been touted to be a major asset of Cyber-Physical Systems (CPS) and its components. By intertwining non-physical and physical processes they seamlessly integrate interdependent computational and physical components. In this contribution we take a closer look on structural constellations of CPS and their components that refer to autonomy. We also take into account development aspects and demonstrate encoding autonomy aspects into a behavior-centered representation scheme for digital twins. It features encapsulation on various layers of abstraction in the course of design and choreography for self-contained while networked operation of CPS as System-of-Systems. As digital twin models created in the course of CPS design activities can be executed automatically, the implementation and adaptation of CPS (components) is intertwined with design activities. Consequently, users can act as designers and experience CPS behavior through digital twin execution interactively. Critical elements, such as managing private data in healthcare, can be monitored and adapted to individual needs.
