Generative AI and Machine Learning Collaboration for Container Dwell Time Prediction via Data Standardization
Integrating Generative AI for data standardization with Machine Learning models significantly improves container dwell time prediction and terminal operational efficiency, reducing relocations by up to 14.68%.
This study introduces a collaborative framework that leverages Generative AI (Gen AI) to standardize unstructured cargo and owner information into structured international codes. This standardized data then enhances Machine Learning (ML) models for predicting Import Container Dwell Time (ICDT). Experiments with real container terminal data demonstrate a 13.88% improvement in Mean Absolute Error (MAE) compared to conventional models. Furthermore, applying these improved predictions to container stacking strategies reduces the number of relocations by up to 14.68%, empirically validating Gen AI's potential to boost productivity and sustainability in port logistics. The framework offers high practicality through its deployability, interpretability, multilingual capability, and cost-effectiveness, with a caching mechanism progressively reducing Gen AI call costs over time.
