    • Three essays in operations management 

      Leung, Ngai-Hang Zachary (Massachusetts Institute of Technology, 2014)
      The thesis applies optimization theory to three problems in operations management. In the first part of the thesis, we investigate the impact of inventory control on the availability of drugs to patients at public health ...
    • Three essays on sequencing and routing problems 

      Bompadre, Agustín (Massachusetts Institute of Technology, 2005)
      In this thesis we study different combinatorial optimization problems. These problems arise in many practical settings where there is a need for finding good solutions fast. The first class of problems we study are vehicle ...
    • Towards a unified theory of procurement contract design : production flexibility, spot market trading, and contract structure 

      Pei, Pamela Pen-Erh (Massachusetts Institute of Technology, 2008)
      We present in this work a unified approach and provide the optimal solution to the pricing problem of option contracts for a supplier of an industrial good in the presence of spot trading. Specifically, our approach fully ...
    • Tractability through approximation : a study of two discrete optimization problems 

      Farahat, Amr, 1973- (Massachusetts Institute of Technology, 2004)
      (cont.) algorithm, at one extreme, and complete enumeration, at the other extreme. We derive worst-case approximation guarantees on the solution produced by such an algorithm for matroids. We then define a continuous ...
    • Tractable multi-product pricing under discrete choice models 

      Keller, Philipp W. (Philipp Wilhelm), 1982- (Massachusetts Institute of Technology, 2013)
      We consider a retailer offering an assortment of differentiated substitutable products to price-sensitive customers. Prices are chosen to maximize profit, subject to inventory/ capacity constraints, as well as more general ...
    • A tractable optimization framework for Air Traffic Flow Management addressing fairness, collaboration and stochasticity 

      Gupta, Shubham, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2012)
      We propose a tractable optimization framework for network Air Traffic Flow Management (ATFM) with an eye towards the future. The thesis addresses two issues in ATFM research: a) fairness and collaboration amongst airlines; ...
    • Tractable stochastic analysis in high dimensions via robust optimization 

      Bandi, Chaithanya (Massachusetts Institute of Technology, 2013)
      Modern probability theory, whose foundation is based on the axioms set forth by Kolmogorov, is currently the major tool for performance analysis in stochastic systems. While it offers insights in understanding such systems, ...
    • Two topics in online auctions 

      Beil, Damian (Massachusetts Institute of Technology, 2003)
      This thesis studies two operations management topics in online auctions, and is divided into two parts. Motivated by the increasing use of ShopBots to scan Internet auctions, the first part of the thesis analytically ...
    • Velocity-based storage and stowage decisions in a semi-automated fulfillment system 

      Yuan, Rong, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2016)
      The supply chain management for an online retailing business is centered around the operations of its fulfillment centers. A fulfillment center receives and holds inventory from vendors, and then uses this inventory to ...
    • Vignettes on robust combinatorial optimization 

      Udwani, Rajan (Massachusetts Institute of Technology, 2018)
      In this thesis, we design and analyze algorithms for robust combinatorial optimization in various settings. First, we consider the problem of simultaneously maximizing multiple objectives, all monotone submodular, subject ...
    • Yield management for telecommunication networks : defining a new landscape 

      Humair, Salal (Massachusetts Institute of Technology, 2001)
      Can airline Yield Management strategies be used to generate additional revenue from spare capacity in telecom networks? Pundits believe "yes", based on several analogies between the industries such as, for instance, ...
