| Abstract Scope |
Generalized graph foundation models offer a flexible approach to constructing data-driven digital twins (ddDTs) for complex technological systems. Unlike traditional, physics-based digital twins that require idealized models built from first principles, ddDTs leverage real-world data streams to provide adaptable and modular representations of system behavior. By using spatiotemporal graph neural networks (st-GNNs) as a foundation, ddDTs capture dynamic interactions and performance characteristics, allowing for accurate monitoring and prediction across a range of applications. This work introduces a unified pipeline to develop graph-based foundation models for diverse systems, including solar photovoltaic fleets, direct ink write additive manufacturing, and laser powder bed fusion. The proposed approach avoids the constraints of physics-based assumptions, enabling a single ddDT architecture to address various performance issues and operational questions without extensive reconfiguration. These foundation models streamline digital twin implementation, supporting efficient, data-driven decision-making in technologically complex environments. |
