Digital Twins for Continuous Deployment in Model-Based Systems Engineering of Cyber-Physical Systems

Abstract Cyber-Physical Systems (CPS) are required to operate over a longer lifetime. As such, their requirements can change, requiring updates to the system to be be rolled out continuously (Continuous Deployment) throughout the system’s lifetime. The DevOps methodology provides a structured, quality assuring way to do so, as it integrates Development and Operations of a system in a continuous cycle. DevOps is generally applied in software development, however in the design of CPS, which follows a ModelBased Systems Engineering (MBSE) approach, it is not. This is because many challenges remain in the application of DevOps in MBSE. Our focus is on creating the foundations for continuous deployment of safety-critical CPS using digital twins of the CPS.k.
