Abstract:
Safety and robustness play a crucial role in the context of the Industrial Internet of Things as autonomous and emergent behavior increase the complexity of Cyber-Physical Production Systems. Given the intractability of exhaustively verifying distributed production systems after modifications, testing and runtime monitoring seem to be two promising methods used to verify correctness in the digitally networked factory. Passive testing and external runtime monitoring are efficient and lightweight techniques that bridge the gap between testing and verification. This paper presents a framework for on-the-fly simulation of a specification relying on the Amazon Web Services Internet of Things architecture and the use of the digital shadow. The feasibility of the proposed architecture is evaluated using an industrial case study.
