Key Takeaways
-
Explainability is critical for real-world deployment: The paper demonstrates that supply chain risk prediction systems need to provide interpretable explanations alongside predictions. Rather than just forecasting which ports will face disruptions, the framework generates natural-language risk narratives that operational teams can actually act on—addressing a key gap where existing systems "prioritize forecasting accuracy without providing operationally interpretable early warnings."
-
AI explanations must be grounded in verifiable evidence: The researchers developed a "directional-consistency validation protocol" to ensure generated explanations actually match the underlying statistical evidence from the model, achieving 99.6% consistency. This addresses a major responsible AI concern: preventing language models from generating plausible-sounding but fabricated justifications for predictions.
-
Combining specialized AI models with LLMs improves trustworthiness: Rather than relying solely on large language models, the framework couples a Temporal Graph Attention Network (which captures supply chain dynamics) with structured LLM reasoning. This hybrid approach constrains the LLM to only explain "verifiable model outputs," reducing hallucination risks while maintaining interpretability.
-
Real-world performance matters for responsible deployment: The system achieved a test recall of 0.504 on actual maritime logistics data over six months, meaning it successfully identified about half of actual disruptions. The paper's emphasis on "chronological split" evaluation (testing on future data) reflects responsible AI practices by avoiding overly optimistic performance estimates.
-
Transparency enables human oversight of critical infrastructure: By providing evidence-grounded explanations of supply chain risks, this framework allows human operators to understand why the system flagged a particular port, enabling them to verify predictions and maintain meaningful control over decisions affecting global logistics.
Abstract
Disruptions at critical logistics nodes pose severe risks to global supply chains, yet existing risk prediction systems typically prioritize forecasting accuracy without providing operationally interpretable early warnings. This paper proposes an evidence-grounded framework that jointly performs supply chain bottleneck prediction and faithful natural-language risk explanation by coupling a Temporal Graph Attention Network (TGAT) with a structured large language model (LLM) reasoning module. Using maritime hubs as a representative case study for global supply chain nodes, daily spatial graphs are constructed from Automatic Identification System (AIS) broadcasts, where inter-node interactions are modeled through attention-based message passing. The TGAT predictor captures spatiotemporal risk dynamics, while model-internal evidence -- including feature z-scores and attention-derived neighbor influence -- is transformed into structured prompts that constrain LLM reasoning to verifiable model outputs. To evaluate explanatory reliability, we introduce a directional-consistency validation protocol that quantitatively measures agreement between generated risk narratives and underlying statistical evidence. Experiments on six months of real-world logistics data demonstrate that the proposed framework outperforms baseline models, achieving a test AUC of 0.761, AP of 0.344, and recall of 0.504 under a strict chronological split while producing early warning explanations with 99.6\% directional consistency. Results show that grounding LLM generation in graph-model evidence enables interpretable and auditable risk reporting without sacrificing predictive performance. The framework provides a practical pathway toward operationally deployable explainable AI for supply chain risk early warning and resilience management.
