    Açıkkollu, Cihan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    This study addresses the application of lean manufacturing concepts to a non-manufacturing environment – a maintenance, repair and overhaul (MRO) company. The goal of this study is to investigate how lean manufacturing ...
  • Supply chain modeling analysis at alternative levels aggregation 
    Demirel, Güven. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    Agent-based modeling t (ABM) and system dynamics (SD) are two methodologies commonly used in the modeling of complex systems, which are conventionally placed at the two ends of the aggregation spectrum. Disaggregated ABM ...
  • Portfolio risk calculation and stochastic portfolio optimization by a copula based approach 
    Karadağ, Durmuş Tarık. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this study we used copulas to calculate the risks of stock portfolios and developed a stochastic portfolio optimization model using copulas to find optimal portfolios. Copula is a multivariate distribution function ...
