Capacitated hub location problems with waiting time at hubs
2011 IEEE International Conference on Industrial Engineering and Engineering Management, 2011A new subject in the scope of capacitated hub location problems is presented. In most of postal networks or data and airline networks, hubs are special facilities that act as consolidation, sorting and distribution centers of flow. Since the models dealing with these problems focus on economic benefits with respect to costs of routing and opening hubs,

Hub Location and the p-Hub Median Problem
Operations Research, 1996Hub facilities serve as switching and transshipment points in transportation and communication networks. Hub networks concentrate flows on the hub-to-hub links and benefit from economies of scale in interhub transportation. Most hub location research has focused on problems where each origin/destination is allocated to a single hub.

The Location of Interacting Hub Facilities
Transportation Science, 1986Hubs are central facilities which act as switching points in networks connecting a set of interacting nodes. This paper develops several location models for hubs. The one-hub siting problem is equivalent to a Weber least cost location model. An empirical example demonstrates the relevance of this model for an understanding of contemporary express ...

Locational disadvantage of the hub
The Annals of Regional Science, 2006We show how spatial evolution is different between the two representative models of economic geography: [Krugman 99:483–499, 1991] and [Ottaviano et al. 43:409–436, 2002]. We analyze the impacts of falling transport costs on the spatial distribution of economic activities and welfare for a network economy consisting of three regions located on a line ...

The Dynamic Uncapacitated Hub Location Problem
Transportation Science, 2011This paper presents a dynamic (or multi-period) hub location problem. It proposes a branch-and-bound algorithm that uses a Lagrangian relaxation to obtain lower and upper bounds at the nodes of the tree. The Lagrangian function exploits the structure of the problem and can be decomposed into smaller subproblems that can be solved efficiently.

Capacity selection for hubs and hub links in hub location problems
International Journal of Management Science and Engineering Management, 2015Hub location problems occur mainly in transportation and telecommunications networks. A hub is a transfer point at which either traffic from several origins is added up and forwarded to another hub, or disaggregated into several streams that are forwarded to their destinations.

The tree‐of‐hubs location problem with interhub stopovers
International Transactions in Operational ResearchAbstract The tree‐of‐hubs location problem (THLP) is a variant of the classical hub location problem, in which the set of hubs must be connected in a tree topology. The key decision variables involve the selection of hub locations, the allocation of spokes to hubs, and the design of a tree‐structured interhub network.
