    • A Fluid Model of Spillback and Bottleneck Phenomena for Determining Dynamic Travel Times 

      Kachani, Soulaymane; Perakis, Georgia (Massachusetts Institute of Technology, Operations Research Center, 2001-08)
      In this paper we introduce travel time models that incorporate spillback and bottleneck phenomena. In particular, we study a model for determining the link travel times for drivers entering a link as well as drivers already ...

    • Monotone Control of Queueing and Production/Inventory Systems 

      Veatch, Michael H.; Wein, Lawrence M. (Massachusetts Institute of Technology, Operations Research Center, 1991-08)
      Weber and Stidham (1987) used submodularity to establish transition monotonicity (a service completion at one station cannot reduce the service rate at another station) for Markovian queueing networks that meet certain ...

    • A Catalog of Steinger Tress Formulations 

      Goemans, Michel X.; Myung, Young-soo (Massachusetts Institute of Technology, Operations Research Center, 1991-05)
      We present some existing and some new formulations for the Steiner tree and Steiner arborescence problems. We show the equivalence of many of these formulations. In particular, we establish the equivalence between the ...
