Graph Neural Networks explored as metamodels for supply chain optimization

A new paper introduces the potential of Graph Neural Networks (GNNs) as metamodels for supply chain optimization, a largely unexplored area. The research outlines key directions, presents a foundational public dataset of supply chain graphs generated by the SupplyNetPy library, and explores GNN architectures for node and network-level predictions. The study analyzes the accuracy-compute trade-off of these GNN surrogates compared to traditional simulation methods, highlighting future possibilities in gradient-based topology optimization and rapid design-space exploration. AI

IMPACT This research could enable faster and more flexible optimization of complex supply chains by leveraging GNNs as efficient surrogates for simulations.
