Digital twins for collaboration and self-integration

Digital twins are digital representations of cyber-physical systems, allowing bi-directional data and control flow between them. In this paper, we introduce the digital twin concept in self-integrating and self-improving systems. Specifically, we highlight the usage of digital twin models for autonomous systems spontaneously interacting with each other and aiming to improve collaboration and mutual safety. We present the main challenges and an initial architecture to enable autonomous cyber-physical systems to collaborate, self-integrate, and self-improve during run-time.
