  • An application of inventory pooling / distribution models in glass industry 
    Ertürk, Can. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Supply chain is a concept in which industrial engineering applications are very important in decision making processes by requiring systematic perspective, scientific approach and correct methodology. Supply chain concept ...
  • Analysis of a supply chain under advance demand information 
    Eş, Emine. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this study we investigate the effects of incorporating advance demand information in a two-echelon distribution model which consists of a central depot and several retailers. The depot is not allowed to hold inventory. ...
  • Analysis of a supply chain with forecast evolution and supply disruption 
    Erbilgin, Hilmi. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    In this thesis, we analyze two supply chain models. In the first model, we develop a centralized supply chain consisting one warehouse and two retailers. The aim of this model is to find the total optimal order quantity ...
  • Analysis of inventory policies under estimation of demand parameters 
    Bozkaya, İrem Cansu. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    The aim of this thesis is to analyze the estimation performance for different characteristics of data in different supply chain systems. In this study, we analyze two different systems. The first section of this thesis ...
  • Analysis of single and two-echelon inventory systems under disruptions in supply 
    Tomsuk, Damla. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    In this thesis, we analyze two different models. In the first model, we consider a two-echelon supply chain with a supplier, a manufacturer and two retailers. The manufacturer is subject to non-stationary supply disruptions. ...
  • Assessing benefits of direct shipment in a deterministic supply chain 
    Meriç, Ebru. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Today's manufacturing establishments have to improve their operations such as logistics, distribution and inventory. Integration of production-distribution systems and scheduling are widely used in manufacturing applications ...
  • Effect of a price driven secondary market on a system with random demand and uncertain costs 
    Gürel, yücel. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    In this thesis, we consider the problem of purchasing a commodity with a uctuating market price so as to maximize its pro t from selling it over two selling season. Over the primary season, the market price evolution is ...
  • Implementation of the Heath-Jarrow-Morton model on the Turkish Government zero-coupon bonds 
    Köken, Ali Tolga. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    The term structure of interest rates explains the relationship among interest rates on default-free securities that vary in their time to maturity. The evolution of the term structure of interest rates through time reflects ...
  • Leasing and remanufacturing strategies with pricing and inventory control 
    Demirok, Nurcan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    We consider infinite horizon inventory policies for a company which satisfies customer demand by either selling or leasing a product. If the product is leased, it can be leased for a different number of periods. The customer ...
  • 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 ...
  • Modeling price and demand interaction in inventory systems 
    İşlier, Bekir Turgut. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    In this thesis, we examine the impact of price on demand in inventory systems with one and two suppliers. We present two models. In the first model, price determines the probability of demand occurrence. In case demand ...
  • Modelling effects of correlation in price competition 
    Yıldız, Engin. (Thesis (M.A.) - Bogazici University. Institute for Graduate Studies in the Social Sciences, 2018., 2018.)
    Firms try to sell their products or services with a predetermined scheme to earn the most profit possible. For this, they first should know the demand characteristics of their product or service. Commonly, the market structure ...
