Alternative Scenarios in Analyzing Florida’s Freight Imbalancege and attractive consumer market. Statistics from the Federal Highway Administration (FHWA) reveal that the total freight tonnage entering the state is nearly double the tonnage leaving the state. This imbalance suggests that many ships, containers, rail cars, and trucks leave the state empty or on作者: 培養(yǎng) 時(shí)間: 2025-3-22 07:03 作者: Expand 時(shí)間: 2025-3-22 11:35 作者: Ventricle 時(shí)間: 2025-3-22 16:20
A Decomposed Fourier-Motzkin Elimination Framework to Derive Vessel Capacity Models in core liner shipping functions such as uptake-, capacity-, and network management. Today, simple models based on volume, weight, and refrigerated container capacity are used for these tasks, which causes overestimations that hamper decision making.

A Note on Alternative Objectives for the Blocks Relocation Problemseen the upcoming discussion whether some objectives are more appropriate than others. While most authors minimize the number of relocations as objective, some minimize the crane’s working time.
