From Reactive to Proactive: An Explainable Risk Awareness Framework for Logistics Cyber-Physical Systems

Abstract

Logistics Cyber-Physical Systems (LCPS) generate large volumes of regulatory and operational texts that encode early signals of safety risks. Converting short, noisy, and domain-specific records into actionable intelligence is difficult due to industrial semantic drift and the limited auditability of black-box predictors. This paper proposes Neuro-Symbolic Logistics Risk Awareness (NS-LRA), a dual-channel framework that integrates lightweight semantic perception with constraint-aware topological reasoning. NS-LRA first maps raw texts to a standardized schema of $K=20$ risk nodes using a dual-weighted embedding mechanism that combines TF-IDF and Word2Vec to mitigate short-text sparsity. It then constructs a directed risk graph by fusing co-occurrence evidence with a domain constraint mask, and derives hierarchical propagation via ISM level partitioning with deep-driver identification via MICMAC analysis. We evaluate NS-LRA on $N=8,435$ records, validated against an annotated subset $(\mathcal{D}_{\text{ann}}=1,500)$) with Fleiss' $\kappa=0.82$ and an expert-defined gold graph. NS-LRA achieves Micro-$\mathrm{F} \mathrm{1}=\text{0. 8 7 9}$ for risk mapping and approximately $22 \times$ lower perrecord CPU latency than fine-tuned BERT on the same test split under the same environment. For topological inference, NS-LRA reports $\text{E P}=\text{0. 9 2 4}$ and $\text{T C}=\text{0. 9 5}$ against the gold graph. These results indicate that NS-LRA can provide an efficient and traceable pipeline for proactive risk governance in LCPS.
