    Tekin, Mehmet Tuğrul. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2018., 2018.)
    This thesis is concerned with collection system design for used products obtained from dealers and is an extension of the works by Aras et al. (2008) and Aras and Aksen (2008). The design decisions involve the locations ...
  • Coverage, sink location and routing problems in wireless sensor networks 
    Güney, Evren. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    Recent advances in electronics and telecommunications have enabled the development of low-cost, low-power multifunctional sensor devices that are powered by batteries and communicating through wireless channels over small ...
  • Data-driven local search heuristics for bilevel network design problems 
    Sevim, İsmail. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    In the Network Design Problem (NDP), one aims to design the configuration of a network by installing links between a set of given nodes and determine the flow of a set of commodities over these installed links. In this ...
  • Disaster mitigation and humanitarian relief logistics 
    Döyen, Alper. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    In this thesis we are interested in two distinct problems within the disaster management context. These problems are modeled by two-stage stochastic integer programming since stochasticity is inherent in natural disasters. ...
  • Leader-follower games for influence spread in social networks 
    Tanınmış, Kübra. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    Influence Maximization Problem involves nding a set of individuals in a social network to trigger an in uence/information spread, i.e., a seed set, such that the maximum possible number of individuals are in uenced. In ...
  • Minimum split coloring 
    Yüzsever, Rıdvan Mert. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    Combinatorial optimization is a very important branch of optimization eld. Many problems in the real world such as transportation, scheduling, production, and telecommunication can be modeled as a combinatorial optimization ...
  • Network flows with conflict constraints 
    Şuvak, Zeynep. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    It is a commonly used approach to model real life problems as network flow prob lems and they appear in a wide range of areas including telecommunication, wireless networks, transportation, healthcare and scheduling. Our ...
  • New neurocomputational approaches for estimating road travel distances and for solving the euclidean traveling salesman problem 
    Aras, Necati. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1999., 1999.)
    Neural networks are among the most rapidly developing new scientific tools. There are numerous publications reporting their success in estimation and optimization. This work concentrates on both of these aspects and applies ...
  • Optimal placement, scheduling and routing to maximize lifetime in wireless sensor networks 
    Türkoğulları, Yavuz Boğaç. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    A wireless sensor network consists of distributed autonomous tiny electronic devices called sensors. They have limited energy and capability for sensing, data processing and communication, but they can collectively behave ...
  • Optimal server placement, service deployment, and resource allocation in next-generation computer network 
    Ahat, Betül. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    With the expansion of mobile devices and new trends in mobile communication technologies, there is an increasing demand for diversified services. To accommodate a large number of services on a common network, it becomes ...
