  • Aremos: |an object oriented visual intaractive linear programming modeler for production planning in a petroleum refinery 
    Birgören, Burak. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1994., 1994.)
    A prototype graphical modeling system, AREMOS (A Refinery Modeling System), has been developed for modeling the production in a petroleum refinery as a linear program within the scope of this study. AREMOS is an object ...
  • Branch - and - price algorithms for the maximum weight perfect matching problem with conflict constraints 
    Çınar, Alim Buğra. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2021., 2021.)
    In this thesis, we consider the Maximum Weight Perfect Matching Problem with Conflict Constraints (MWPMC), which is a generalization of the well-known the Maxi mum Weight Perfect Matching Problem (MWPMP). Although MWPMC ...
  • Capacitated facility location problem with customer and facility differentiation 
    Çavuş, Özlem. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    This thesis focuses on an extension of the capacitated facility location problem. Every demand point consists of multiple customer classes whose demands are satisfied by facilities having different capacities and costs for ...
  • Event and clock based representations of time in mathematical optimization 
    Sürer, Özge. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Time representation is one of the most important issues in mathematical optimization in terms of computational time and e ciency. The discrete time formulation requires large number of binary variables which a ects the ...
  • Exact solution methods for the assignment problem with conflict constraints 
    Arslan, Elif. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    The Assignment Problem with Conflict Constraints (APC) deals with finding a maximum weight assignment in the presence of incompatibilities. The incompatibilities are constituted by the conflicting edge pairs such that both ...
  • Heuristics for the probabilistic capacitated multi-facility weber problem 
    Durmaz, Engin. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this study, we consider the probabilistic capacitated multi-facilityWeber problem with general distance functions and probability density functions where customer locations are assumed to be random variables. The aim ...
  • Lagrangean heuristic fio the capacitated multi-facility location allocation problem 
    Avcı, Buket. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this study, we consider the capacitated multi-facility location-allocation problem, also called multi-facility Weber problem. It is concerned with the determination of the location of m new facilities having known ...
  • Mission based component plans 
    Keskin, M. Emre. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    One of the widely used methods of system reliability test plans is based on the idea of computing the component test plans that ensure prespecified reliability levels for those components. Another widely used approach ...
  • Optimal placement, scheduling and routing to maximize lifetime in wireless sensor networks under connectivity restrictions 
    Kabakulak, Banu. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    A wireless sensor network consists of distributed autonomous electronic devices called sensors. They are capable of sensing the changes in their vicinity, process the information as data packets and transmit the data to ...
  • Optimal sensor deployment to increase the security of the minimal exposure path 
    Karabulut, Ezgi. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    Wireless Sensor Networks (WSN) are based on collaborative work of a collection of sensors which are low-cost, multi-functional devices. There is a wide range of application areas of WSN including border surveillance and ...
  • Quay length optimization using inventory and stochastic knapsack models 
    Özgüven, Eren Erman. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Within this study, it is aimed to develop a method to determine the optimal quaylength. Since one of the most significant drawbacks of the maritime transportation isthe delays encountered in ports where loading and unloading ...
  • Solving the capacitated multifacility Weber problem approximately 
    Boyacı, Burak. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    In this study, we consider the capacitated multifacility Weber problem which is concerned with locating m facilities in the plane, and allocating their limited capacities to n customers at minimum total cost. In this group ...
