Synchronizing Model-Based System Engineering for Digital Twins

This technical report presents the Authoritative Broker of Truth (ABoT) paradigm, which synchronizes model-based system engineering with cross-disciplinary simulation to create digital twins. Digital twins are defined as virtual representations of real-world entities that require interdisciplinary cooperation for their development. The report outlines the core processes necessary for building and evolving digital twins, including design, simulation, analysis, connection, and evolution. It emphasizes the importance of maintaining synchronization between the digital twin and its real-world counterpart throughout its lifecycle. The report also discusses the Authoritative Source of Truth (ASoT), which serves as a centralized data repository for managing the artifacts associated with digital twins. Furthermore, it highlights the significance of validation, verification, and uncertainty quantification (VVUQ) in ensuring the reliability of digital twins. A real-world case study illustrates the application of the ABoT paradigm in determining the necessary hardware for receiving free over-the-air television.
