A Holistic System Lifecycle Engineering Approach – Closing the Loop between System Architecture and Digital Twins

Abstract This contribution introduces an approach for the optimization of smart products and systems in the early development phases through a Closed-Loop Systems Engineering approach. This approach – holistic in terms of considering the overall system and its usage context, interdisciplinary, overreaching multiple lifecycle phases, and supported methodologically as well as tool-wise – combines aspects from both Model-Based Systems Engineering and Product resp. System Lifecycle Management to optimize the system by using advanced verification and validation methods and techniques, in particular Model-, Twin- and System-in-the-Loop, and seamless feedback of product usage data to the early development phase. This approach has been prototypically applied at the example of a test bed of an autonomous construction area system of systems.
