Abstract

This paper addresses the optimization of truck pulling for bulk unloading operations at the Port of Itaqui, a critical logistics hub in Brazil. The current manual process often leads to inefficiencies such as congestion, delays, and increased emissions. To tackle these challenges, we propose a mathematical model for responsive truck pulling to minimize queue imbalances considering emissions while maintaining operational efficiency. A port activity simulator was developed to evaluate the model under various demand and supply scenarios, comparing its performance against a benchmark algorithm replicating operator behavior. Results demonstrate that the proposed model reduces truck congestion in the primary area by up to 50% without increasing unloading times, offering a more balanced and sustainable approach. The findings enhance port logistics and provide a framework for automating truck dispatch processes in bulk cargo operations. Future work involves integrating the model into real-world applications and extending its capabilities to multi-terminal environments.
