    • Exact solution methodologies for the p-center problem under single and multiple allocation strategies 

      Çalık, Hatice (Bilkent University, 2013)
      The p-center problem is a relatively well known facility location problem that involves locating p identical facilities on a network to minimize the maximum distance between demand nodes and their closest facilities. The ...
    • Fiber optical network design problems : case for Turkey 

      Yazar, Başak (Bilkent University, 2013)
      The problems within scope of this thesis are based on an application arising from one of the largest Internet service providers operating in Turkey. There are mainly two different problems: the green field design and ...
    • Hub & regenerator location and survivable network design 

      Özkök, Onur (Bilkent University, 2010)
      With the vast development of the Internet, telecommunication networks are employed in numerous different outlets. In addition to voice transmission, which is a traditional utilization, telecommunication networks are now ...
    • The hub covering problem over incomplete hub networks 

      Kalaycılar, Murat (Bilkent University, 2006)
      The rising trend in the transportation and telecommunication systems increases the importance of hub location studies in recent years. Hubs are special types of facilities in many-to-many distribution systems where flows ...
    • Hub location and Hub network design 

      Alumur, Sibel Alev (Bilkent University, 2009)
      he hub location problem deals with finding the location of hub facilities and allocating the demand nodes to these hub facilities so as to effectively route the demand between origin–destination pairs. Hub location ...
    • Hub location under competition 

      Mahmutoğulları, Ali İrfan (Bilkent University, 2013)
      Hubs are consolidation and dissemination points in many-to-many flow networks. The hub location problem is to locate hubs among available nodes and allocate non-hub nodes to these hubs. The mainstream hub location studies ...
    • Modeling and heuristic approaches for the Hub covering problem over incomplete Hub networks 

      Çalık, Hatice (Bilkent University, 2009)
      Hubs are the accumulation points within the transportation and the telecommunication networks that collect and distribute the flow or data, which is originated from a starting point and needs to be transferred to a ...
    • Outer approximation algorithms for the congested p-median problem 

      Şelfun, Selva (Bilkent University, 2011)
      In this thesis, we study a generalization of the p-median problem, which is a well-known facility location problem. Given a set of clients, a set of potential facilities, and a positive integer p, the p-median problem ...
    • P-hub maximal covering problem and extensions for gradual decay functions 

      Peker, Meltem (Bilkent University, 2013)
      Hubs are special facilities that serve as switching, transshipment and sorting nodes in many to many distribution systems. The hub location problem deals with the selection of the locations of hub facilities and finding ...
    • Routing and scheduling decisions in the hierarchical hub location problem 

      Dükkancı, Okan (Bilkent University, 2013)
      Hubs are facilities that consolidate and disseminate flow in many-to-many distribution systems. The hub location problem considers decisions including the locations of hubs on a network and also the allocations of the ...
