Synthetic Data Generation for Supply Chain

Synthetic data generation has emerged as a foundational enabler of supply chain AI research, addressing three persistent challenges: data scarcity, confidentiality, and the difficulty of constructing reproducible benchmarks. Real-world supply chain data is typically proprietary, fragmented across trading partners, and subject to strict regulatory and contractual constraints—creating a significant barrier for academic research and the fair comparison of AI methods.

Modern synthetic data techniques—ranging from generative adversarial networks (GANs) and variational autoencoders to diffusion models, conditional generative models, and agent-based simulation—can produce artificial datasets that preserve the statistical distributions, temporal dynamics, and network topology of real supply chains. These synthetic datasets enable researchers to train and evaluate models for demand forecasting, delay prediction, supplier link prediction, and risk analysis without ever exposing sensitive operational data. They also support differential-privacy and secure-multiparty-computation pipelines, making them a natural complement to privacy-preserving learning paradigms such as federated learning.

Research from the Supply Chain AI Lab at the University of Cambridge has contributed to this field through the release of open synthetic supply chain datasets and benchmarks—including networks for link prediction, shipment records for delay forecasting, and simulated procurement environments for agent-based research. These efforts are part of a broader community movement towards open, reproducible, and privacy-respecting supply chain AI.
