Energy Mix Optimization for Yard Trucks in Container Ports Under Low-Carbon Constraints

With the rapid expansion of global trade, the environmental impacts of port operations have attracted increasing attention. This study develops a mixed-integer programming (MIP) model to identify low-carbon energy mix replacement pathways for yard trucks (YTs), aiming to minimize total cost under low-carbon constraints...

A Vessel-Aware Graph Neural Network Framework for Port Motorway Traffic State Estimation

A novel TSE method named HGCN-VA is proposed, enabling a real-time inductive inference based on a graph neural network (GNN), and extensive experiments demonstrate that HGCN-VA outperforms baselines in TSE accuracy.
