Hierarchical hub location problem for freight network design
Hierarchical hub location problem for freight network design is a scholarly work, published in 2018 in ''IET Intelligent Transport Systems''. The main subjects of the publication include transportation engineering, vehicle routing problem, humanitarian logistics, operations research, computer science, and engineering. Most of the models used to design hub networks have considered a single level of hub type, but they do not reflect the hub scale by freight volume in the network.
