Automated machine learning (AutoML) models can predict natural hazard-induced seaport disruptions. Neural networks achieved the highest accuracy, highlighting key factors like hazard severity and recovery efficiency for improved seaport resilience.
Area of Science:
- Maritime logistics and disaster management.
- Application of artificial intelligence in supply chain risk assessment.
Background:
- Seaports are critical for global trade, but natural hazards threaten their operations and economic stability.
- Predicting seaport disruptions from natural hazards is essential for ensuring supply chain continuity.
Purpose of the Study:
- To evaluate the effectiveness of automated machine learning (AutoML) models in predicting natural hazard-induced seaport disruptions.
- To identify the most accurate AutoML models and influential features for disruption prediction.
Main Methods:
- Utilized a dataset of seaport disruptions from 2010 to 2019.
- Evaluated 24 AutoML models across seven categories, including neural networks and support vector machines.
- Performed feature ranking to identify key factors influencing disruption prediction.
Main Results:
- Neural networks demonstrated the highest predictive accuracy (94.95%), with wide neural networks achieving 96.44%.
- Support vector machines showed the lowest accuracy (76.32%).
- Hazard "severity" and "recovery" were identified as the most influential factors.
Conclusions:
- AutoML models, particularly neural networks, show strong potential for predicting seaport disruptions.
- Findings provide insights for enhancing seaport resilience and preparedness against natural hazards.
- Future research should focus on incorporating more granular data and ensemble models for improved predictive capabilities.
