    • Buyout prices in online auctions 

      Gupta, Shobhit (Massachusetts Institute of Technology, 2006)
      Buyout options allow bidders to instantly purchase at a specified price an item listed for sale through an online auction. A temporary buyout option disappears once a regular bid above the reserve price is made, while a ...
    • Capacity expansion in contemporary telecommunication networks 

      Sivaraman, Raghavendran (Massachusetts Institute of Technology, 2007)

    • The case for coordination : equity, efficiency and passenger impacts in air traffic flow management 

      Fearing, Douglas (Douglas Stephen) (Massachusetts Institute of Technology, 2010)
      In this thesis, we develop multi-resource integer optimization formulations for coordinating Traffic Flow Management (TFM) programs with equity considerations. Our multi-resource approaches ignore aircraft connectivity ...
    • Combinatorial optimization problems with concave costs 

      Stratila, Dan (Massachusetts Institute of Technology, 2009)
      In the first part, we study the problem of minimizing a separable concave function over a polyhedron. We assume the concave functions are nonnegative nondecreasing on R+, and the polyhedron is in RI' (these assumptions can ...
    • Combinatorial structures in online and convex optimization 

      Gupta, Swati, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2017)
      Motivated by bottlenecks in algorithms across online and convex optimization, we consider three fundamental questions over combinatorial polytopes. First, we study the minimization of separable strictly convex functions ...
    • Competition and loss of efficiency : from electricity markets to pollution control 

      Kluberg, Lionel J. (Lionel Jonathan) (Massachusetts Institute of Technology, 2011)
      The thesis investigates the costs and benefits of free competition as opposed to central regulation to coordinate the incentives of various participants in a market. The overarching goal of the thesis is to decide whether ...
    • Competitive multi-period pricing for perishable products 

      Sood, Anshul, 1978- (Massachusetts Institute of Technology, 2004)
      Pricing of a perishable product over a multi-period time horizon is a challenging problem under an oligopolistic market framework. We propose and study a model for multi-period pricing in an oligopolistic market for a ...
    • Constructing learning models from data : the dynamic catalog mailing problem 

      Sun, Peng, 1974- (Massachusetts Institute of Technology, 2003)
      The catalog industry is a large and important industry in the US economy. One of the most important and challenging business decisions in the industry is to decide who should receive catalogs, due to the significant mailing ...
    • Coordinating inventory control and pricing strategies 

      Chen, Xin, 1973- (Massachusetts Institute of Technology, 2003)
      Traditional inventory models focus on effective replenishment strategies and typically assume that a commodity's price is exogenously determined. In recent years, however, a number of industries have used innovative pricing ...
    • Correlation decay and decentralized optimization in graphical models 

      Weber, Theophane (Massachusetts Institute of Technology, 2010)
      Many models of optimization, statistics, social organizations and machine learning capture local dependencies by means of a network that describes the interconnections and interactions of different components. However, in ...
    • Data, models and decisions for large-scale stochastic optimization problems 

      Mišić, Velibor V (Massachusetts Institute of Technology, 2016)
      Modern business decisions exceed human decision making ability: often, they are of a large scale, their outcomes are uncertain, and they are made in multiple stages. At the same time, firms have increasing access to data ...
    • Data-driven algorithms for operational problems 

      Cheung, Wang Chi (Massachusetts Institute of Technology, 2017)
      In this thesis, we propose algorithms for solving revenue maximization and inventory control problems in data-driven settings. First, we study the choice-based network revenue management problem. We propose the Approximate ...
    • Data-driven approach to health care : applications using claims data 

      Bjarnadóttir, Margrét Vilborg (Massachusetts Institute of Technology, 2008)
      Large population health insurance claims databases together with operations research and data mining methods have the potential of significantly impacting health care management. In this thesis we research how claims data ...
