      The latest arrival hub location problem for cargo delivery systems with stopovers 

      Yaman, H.; Kara, B. Y.; Tansel, B. C. (Elsevier, 2007)
      In this paper, we concentrate on the service structure of ground-transportation based cargo delivery companies. The transient times that arise from nonsimultaneous arrivals at hubs (typically spent for unloading, loading, ...

      Network hub location problems: The state of the art 

      Alumur, S.; Kara, B. Y. (Elsevier, 2008)
      Hubs are special facilities that serve as switching, transshipment and sorting points in many-to-many distribution systems. The hub location problem is concerned with locating hub facilities and allocating demand nodes to ...

      Projecting the flow variables for hub location problems 

      Labbé, M.; Yaman, H. (John Wiley & Sons, 2004)
      We consider two formulations for the uncapacitated hub location problem with single assignment (UHL), which use multicommodity flow variables. We project out the flow variables and determine some extreme rays of the ...

      Polyhedral analysis for the uncapacitated hub location problem with modular arc capacities 

      Yaman, H. (Society for Industrial and Applied Mathematics, 2005)
      We consider the problem of installing a two-level telecommunication network. Terminal nodes communicate with each other through hubs. Hubs can be installed on terminal nodes and they are interconnected by a complete network. ...

      Solving the hub location problem with modular link capacities 

      Yaman, H.; Carello, G. (Elsevier, 2005)
      This paper deals with a capacitated hub location problem arising in the design of telecommunications networks. The problem is different from the classical hub location problem in two ways: the cost of using an edge is not ...

      Star p-hub median problem with modular arc capacities 

      Yaman, H. (Elsevier, 2008)
      We consider the hub location problem, where p hubs are chosen from a given set of nodes, each nonhub node is connected to exactly one hub and each hub is connected to a central hub. Links are installed on the arcs of the ...

      Solving the hub location problem in a star-star network 

      Labbé, M.; Yaman, H. (John Wiley & Sons, 2008)
      We consider the problem of locating hubs and assigning terminals to hubs for a telecommunication network. The hubs are directly connected to a central node and each terminal node is directly connected to a hub node. The ...

      The hierarchical hub median problem with single assignment 

      Yaman, H. (Elsevier, 2009)
      We study the problem of designing a three level hub network where the top level consists of a complete network connecting the so-called central hubs and the second and third levels are unions of star networks connecting ...

      A branch and cut algorithm for hub location problems with single assignment 

      Labbé, M.; Yaman, H.; Gourdin, E. (Springer, 2005)
      The hub location problem with single assignment is the problem of locating hubs and assigning the terminal nodes to hubs in order to minimize the cost of hub installation and the cost of routing the traffic in the network. ...

      A hub covering network design problem for cargo applications in Turkey 

      Alumur, S.; Kara, B. Y. (Palgrave Macmillan, 2009)
      Hub location problems involve locating hub facilities and allocating demand nodes to hubs in order to provide service between origin-destination pairs. In this study, we focus on cargo applications of the hub location ...
