    • Effective contracts in supply chains 

      Shum, Wanhang (Massachusetts Institute of Technology, 2007)
      In the past decade, we have seen significant increase in the level of outsourcing in many industries. This increase in the level of outsourcing increases the importance of implementing effective contracts in supply chains. ...
    • Effectiveness and design of sparse process flexibilities 

      Wei, Yehua, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      The long chain has been an important concept in the design of flexible processes. This design concept, as well as other sparse flexibility structures, have been applied by the automotive and other industries as a way to ...
    • Efficient capacity allocation in a collaborative air transportation system 

      Hall, William D. (William David), 1968- (Massachusetts Institute of Technology, 1999)
      This thesis proposes methods of allocating airport capacity to the users of the National Airspace System (NAS) during periods in which demand for the resources exceeds capacity. A metric by which the proposed methods are ...
    • Emission regulations in the electricity market : an analysis from consumers, producers and central planner perspectives 

      Figueroa Rodriguez, Cristian Ricardo (Massachusetts Institute of Technology, 2013)
      In the first part of this thesis, the objective is to identify optimal bidding strategies in the wholesale electricity market. We consider asymmetric producers submitting bids to a system operator. The system operator ...
    • Essays in financial engineering 

      Haugh, Martin B. (Martin Brendan), 1971- (Massachusetts Institute of Technology, 2001)
      This thesis consists of three essays that apply techniques of operations research to problems in financial engineering. In particular, we study problems in portfolio optimization and options pricing. The first essay is ...
    • Essays on inventory, pricing and financial trading strategies 

      Lu, Ye, Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
      In a multi-product market, if one product stocks out, consumers may substitute to competing products. In this thesis, we use an axiomatic approach to characterize a price-dependent demand substitution rule, and provide a ...
    • Essays on optimization and incentive contracts 

      Goundan, Pranava Raja (Massachusetts Institute of Technology, 2007)
      (cont.) In the second part of the thesis, we focus on the design and analysis of simple, possibly non-coordinating contracts in a single-supplier, multi-retailer supply chain where retailers make both pricing and inventory ...
    • Essays on the emiprical properties of stock and mutual fund returns 

      Taylor, Jonathan David, 1969- (Massachusetts Institute of Technology, 2000)
      Survivorship bias influences statistical inference in Finance. Through a series of Monte Carlo simulations in the style of Brown, Goetzmann, Ibbotson, and Ross {1992), we study the sampling distribution of the mean return, ...
    • Essays on variational inequalities and competitive supply chain models 

      Zaretsky, M. (Marina) (Massachusetts Institute of Technology, 2004)
      In the first part of the thesis we combine ideas from cutting plane and interior point methods to solve variational inequality problems efficiently. In particular, we introduce "smarter" cuts into two general methods for ...
    • Exploration vs. exploitation : reducing uncertainty in operational problems 

      Shaposhnik, Yaron (Massachusetts Institute of Technology, 2016)
      Motivated by several core operational applications, we introduce a class of multistage stochastic optimization models that capture a fundamental tradeoff between performing work under uncertainty (exploitation) and investing ...
    • Fairness in operations : from theory to practice 

      Trichakis, Nikolaos K (Massachusetts Institute of Technology, 2011)
      This thesis deals with two basic issues in resource allocation problems. The first issue pertains to how one approaches the problem of designing the "right" objective for a given resource allocation problem. The notion of ...
    • Forecast-driven tactical planning models for manufacturing systems 

      Chhaochhria, Pallav (Massachusetts Institute of Technology, 2011)
      Our work is motivated by real-world planning challenges faced by a manufacturer of industrial products. In the first part of the thesis, we study a multi-product serial-flow production line that operates in a low-volume, ...
    • From data to decisions in healthcare : an optimization perspective 

      Weinstein, Alexander Michael (Massachusetts Institute of Technology, 2017)
      The past few decades have seen many methodological and technological advances in optimization, statistics, and machine learning. What is still not well understood is how to combine these tools to take data as inputs and ...
    • From data to decisions through new interfaces between optimization and statistics 

      Kallus, Nathan (Massachusetts Institute of Technology, 2015)
      The growing availability of data is creating opportunities for making better decisions, but in many circumstances it is yet unknown how to correctly leverage this data in systematic and optimal ways. In this thesis, we ...
    • General superposition strategies and asset allocation 

      Kaminski, Kathryn Margaret (Massachusetts Institute of Technology, 2007)
      Investors commonly use stopping rules to help them get in and out of their investment positions. Despite their widespread use and support from behavioral finance, there has been little discussion of their impact on portfolio ...
    • The Gomory-Chvátal closure : polyhedrality, complexity, and extensions 

      Dunkel, Juliane (Massachusetts Institute of Technology, 2011)
      In this thesis, we examine theoretical aspects of the Gomory-Chvátal closure of polyhedra. A Gomory-Chvátal cutting plane for a polyhedron P is derived from any rational inequality that is valid for P by shifting the ...
    • Governing the human capitalists : ownership and authority in the advertising and airline industries 

      Von Nordenflycht, Andrew Gustaf, 1969- (Massachusetts Institute of Technology, 2004)
      Theorists suggest the rising value of human capital will mean greater participation by employees in the ownership and governance of firms. This thesis explores aspects of these claims by analyzing the competitive effects ...
