Abstract

Integrating Digital Twins (DTs) with Systems of Systems (SoSs) offers transformative potential for optimizing complex, interconnected systems. However, implementing a DT for an SoS poses several challenges due to the independence and diversity of Constituent Systems (CSs), as well as SoS-specific characteristics such as geographic distribution, evolutionary development, and emergent behavior. This study proposes a novel architectural framework for an SoS DT, featuring a layered design that combines individual DTs for each CS with a global SoS DT layer to oversee and coordinate their interactions. By bridging limitations found in standalone DTs, this structure enables a cohesive and adaptive digital representation of the SoS, addressing the challenges of autonomy and extensibility. The framework aligns with fundamental SoS characteristics, paving the way for enhanced system management, predictive analysis, and performance monitoring, while also underscoring the need for a standardized metamodel to support resilient SoS DT development.
