  • An approach to the FMS tool allocation problem with material handling considerations 
    Koşucuoğlu, Deniz. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    The aim of this thesis is to propose solution methods for solving the tool allocation problem with material handling considerations faced in a Flexible Manufacturing System (FMS). The FMS is assumed be capable of handling ...
  • Admission and termination control of a two class loss system 
    Ulukuş, Mehmet Yasin. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    In this thesis, we consider admission and termination control policies in a Markovian loss system with two classes of jobs. A class is characterized by the arrival and service rates, in addition to a fixed reward and ...

  • Unit disk graph coloring and its reoptimization 
    Boyacı, Arman. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    A unit disk graph (UDG) is a graph of intersection of a set of unit disks in Euclidean plane. Motivated by frequency assignment problem in telecommunication, we consider minimum vertex coloring of unit disk graphs (ColorUDG) ...
  • A deterministic demand inventory model with advance supply information 
    Küçük, Bilge (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    In this study we consider a periodic review, single-item inventory model under non-stationary supply availability with advance supply availability information. We have a dynamic deterministic demand and the objective is ...
  • Compenting vendors in the telecom value chain 
    Gök, Ünal. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
