  • Competitive models of telecommunication supply chains with effort dependent demand 
    Çanakoğlu, Ethem. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2004., 2004.)
    In this study, a model for telecommunication supply chains is developed. A two-stage supply chain consisting of one operator and one vendor is studied in both single period and multi period settings. The operator faces a ...
  • Competitive supply chain management among non-identical suppliers under capacity constraint 
    Candeniz, Ozan. (Thesis (M.A.) - Bogazici University. Institute for Graduate Studies in the Social Sciences, 2018., 2018.)
    A supply chain problem is considered that consists of a major manufacturer and two non-identical suppliers who supply a special product to the manufacturer. The aim of both suppliers is to work with the manufacturer by ...
  • Complex representations of finite general linear groups
