  • Karp, Richard M.; Orlin, James B., 1953- (Massachusetts Institute of Technology, Operations Research Center, 1980-10)
    Let G = (V,E) be a digraph with n vertices including a special vertex s. Let E' C E be a designated subset of edges. For each e E E there is an associated real number fl(e). Furthermore, let 1 if e E E' f2(e): 0 if e E-E' ...
  • Marsten, Roy E.; Morin, Thomas L. (Massachusetts Institute of Technology, Operations Research Center, 1976-03)
    A family of integer programs is considered whose right-hand-sides lie on a given line segment L. This family is called a parametric integer program(PIP). Solving a (PIP) means finding an optimal solution for every program ...

  • Magnanti, Thomas L.; Orlin, James B., 1953- (Massachusetts Institute of Technology, Operations Research Center, 1985-10)
    The traditional perturbution (or lexicographic) methods for resolving degeneracy in linear programming impose decision rules that eliminate ties in the simplex ratio rule and, therefore,restrict the choice of exiting basic ...
  • Bertsimas, Dimitris J.; Teo, Chungpiaw (Massachusetts Institute of Technology, Operations Research Center, 1994)
  • Soldner, Mallory Jo (Massachusetts Institute of Technology, 2009)
    This research seeks to address potential "passenger-centric" modifications to the way that ground holding delays are allocated in Ground Delay Programs. The allocation of landing slots to arriving flights during time periods ...
  • Shenk, Kimberly N (Massachusetts Institute of Technology, 2010)
    Myocardial infarction is a derivative of heart disease that is a growing concern in the United States today. With heart disease becoming increasingly predominant, it is important to not only take steps toward preventing ...

  • Ou, Jihong; Wein, Lawrence M. (Massachusetts Institute of Technology, Operations Research Center, 1990-09)
    The goal of this paper is to assess the improvement in performance that might' be achieved by optimally scheduling a multiclass open queueing network. A stochastic process is defined whose steady-state mean value is less ...
  • Diwan, Sarvee (Massachusetts Institute of Technology, 2010)
    This thesis evaluates the performance of Dynamic Programming (DP) models as applied to airline Revenue Management (RM) compared to traditional Revenue Management models like EMSRb as DP models offer a theoretically attractive ...
  • O'Hair, Allison Kelly (Massachusetts Institute of Technology, 2013)
    In this thesis, we present a system to make personalized lifestyle and health decisions for diabetes management, as well as for general health and diet management. In particular, we address the following components of the ...
  • Seidel, Scott B (Massachusetts Institute of Technology, 2010)
    Combat outposts (COPs) are small, well-protected bases from which soldiers reside and conduct operations from. Used extensively during the "Surge" in Iraq, COPs are usually established in populated areas and are prevalent ...
  • Elliot, Dorothy P. (Massachusetts Institute of Technology, Operations Research Center, 1978-03)
    A mixed integer programming model for planning water resources investments is presented. The model is a sequencing model applied to the Vardar-Axios river basin in Yugoslavia and Greece. The structure of the model is ...
  • McAllister, Daniel B. (Daniel Brandford) (Massachusetts Institute of Technology, 2006)
    We consider the problem of assigning a scarce number of interceptors to a wave of incoming atmospheric re-entry vehicles (RV). In this single wave, there is time to assign interceptors to a wave of incoming RVs, gain ...
  • Sasanuma, Katsunobu (Massachusetts Institute of Technology, 2009)
    Drivers in urban neighborhoods who cruise streets, seeking inexpensive on-street parking create a significant fraction of measured traffic congestion. The solution to this problem is to reduce the total traffic volume ...
  • Hall, Leslie A.; Magnanti, Thomas L. (Massachusetts Institute of Technology, Operations Research Center, 1989-12)
    In a two-capacitated spanning tree of a complete graph with a distinguished root vertex v, every component of the induced subgraph on V\{v} has at most two vertices. We give a complete,non-redundant characterization of the ...

  • Lauprête, Geoffrey J. (Geoffrey Jean), 1972- (Massachusetts Institute of Technology, 2001)
    This thesis revisits the portfolio selection problem in cases where returns cannot be modeled as Gaussian. The emphasis is on the development of financially intuitive and statistically sound approaches to portfolio risk ...
  • Martínez-de-Albéniz, Victor, 1978- (Massachusetts Institute of Technology, 2004)
    Traditionally, industrial buyers have focused on long-term contracts for many of their purchasing needs. Recently, however, some high-tech manufacturers have started looking at more flexible contracts for non-strategic ...
