    In this study, due date assignment problem is addressed in a single machine dynamic and stochastic environment with family setups. A due date is to be assigned for each new job immediately at the time of its arrival. While ...
  • Bilge, Ümit. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1991., 1991.)
    The scheduling of material handling system is a crital issue in a Flexible Manufacturing System (FMS), although it has little importance in a job shop. The purpose of this dissertation is to exploit the interactions between ...
  • Dingeç, Kemal Dinçer. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    The valuation of path dependent and multivariate options require efficient numerical methods, as their prices are not available in closed form. Monte Carlo simulation is one of the widely used techniques. Although simulation ...
  • Başoğlu, İsmail. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Monte Carlo simulation is frequently the only method available for computing nancial risk, particularly under the realistic and complex portfolio models. The naive simulation generally leads to large con dence intervals ...
  • İşeri, Ali. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    In this study, a new and novel method of developing both ergonomic and efficient keyboard layouts is introduced based on the touch typing principles. A multi objective mathematical model with two objectives is defined. One ...
  • Keskin, M. Emre. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    The design of a Wireless sensor network (WSN) involves the optimal deployment and activity scheduling of the sensors as well as optimal deployment or routing of sinks and optimal routing of data flows. In this thesis, we ...
  • 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 ...
