  • A logistics system design for fast moving consumer goods 
    Oluk, Atılım. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    This research addresses to a logistics system design for fast moving consumer goods. Within the context of the thesis, the distribution system of cold products starting from the ordering process and ending with the placement ...
  • Implementation of distributed workflow management systems 
    Çıtakoğlu, Hande. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In this work, workflow management systems are investigated and a workflow engine which can be used in the competitive and dynamic business environment for managing distributed workflows is proposed. The currently used ...
  • Assessment of a toll plaza bridge using traffic microsimulation 
    Özturan, Tayfun. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Today, traffic congestion has been a problem leading into dramatic consequences, such as driver’s stress caused by waiting in the traffic, economic losses due to wasted time and oil, reduced quality of air because of the ...
  • Generic dynamic pattrens: testing by empirical evidence 
    Soylu, Sercan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Validation in system dynamics (SD) models can be classified into two major groups, structure and behavior validation. While behavior validation involves comparison of the model output with the real data, the structural ...
  • Modeling and analysis of a kit management problem 
    Kızılcık, Güler. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this study, we consider a multi-item inventory system in which customers may order different but possibly overlapping kits. Customer demand for a kit follows a Poisson process where there is a fixed probability for each ...
  • Optimal multi-period pricing strategy for remanufacturable leased goods 
    Yürülmez, Sevil. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
