Hub-and-spoke intermodal networks offer a valuable framework for understanding the structure, function, and characteristics of intermodal networks (Meng and Wang, 2011). These networks demonstrate the advantages of economies of scale and strategic location in container transport (Basallo-Triana et al., 2021).Dec 22, 2022 · The hub-and-spoke network (HSN) design generally assumes direct transportation between a spoke node and its assigned hub, while the spoke’s demand may be far less than a truckload. Therefore, the total number of trucks on the network increases unnecessarily. We form a drone-based traveling salesman problem (TSP-D) for the cluster of spokes assigned to a hub. A truck starts from the hub ... The hub’s economic effects in a pure multiple-hub, hub-and-spoke network, however, depend on economies of scale in transport. O’Kelly and Bryan (1998) formulated a nonlinear integer program showing that the higher the economies of scale, the greater the freight flow accumulated in the hub-to-hub links.Motivated by the strategic importance of congestion management, in this paper we present a model to design hub-and-spoke networks under stochastic demand and congestion.
