abstract = {Cold-chain logistics requires continuous visibility of environmental conditions because temperature excursions, excessive humidity, transit delays and equipment faults can compromise temperature-sensitive goods. This paper presents CHAINGUARD AI, a prototype framework integrating shipment monitoring, machine-learning-based risk estimation, anomaly detection, rule-based alerts, route comparison and what-if scenario analysis. The supplied software uses a React and TypeScript frontend, a FastAPI backend, SQLAlchemy persistence, a Random Forest classifier and an Isolation Forest detector. The model feature schema includes temperature, relative humidity, transit duration, delivery delay, temperature exposure and recent temperature change.
A predicted positive-class probability is mapped to a 0–100 prototype risk score and four display bands. Source-code inspection confirms that the current v0.1.0 model labels, seeded shipment records, telemetry and route inputs are synthetic; the supplied archive does not contain ESP32 firmware or a live DHT22 ingestion endpoint. To demonstrate the analytical workflow without presenting fabricated field evidence, a separate reproducible synthetic benchmark was generated using the same six-feature schema and a synthetic event-generation rule.
On a stratified held-out synthetic test partition, the Random Forest achieved 85.60% accuracy, 53.44% recall, 56.45% F1-score and 0.811 ROC-AUC; logistic regression achieved 82.67% accuracy, 61.83% recall, 55.48% F1-score and 0.836 ROC-AUC. These values are simulation-only and cannot be interpreted as real shipment prediction performance. The paper documents the architecture, implementation, synthetic experiment and validation requirements for subsequent real-world testing.},
