Heuristics, LPs, and Generalizations of Trees on Trees
(Massachusetts Institute of Technology, Operations Research Center, 199301)We study a class of models, known as overlay optimization problems, with a "base" subproblem and an "overlay" subproblem, linked by the requirement that the overlay solution be contained in the base solution. In some ... 
Heuristics, LPs, and Trees on Trees: Network Design Analyses
(Massachusetts Institute of Technology, Operations Research Center, 199401)We study a class of models, known as overlay optimization problems, with a "base" subproblem and an "overlay" subproblem, linked by the requirement that the overlay solution be contained in the base solution. In some ... 
A Hybrid Approach to Discrete Mathematical Programming
(Massachusetts Institute of Technology, Operations Research Center, 197603)The dynamic programming and branchandbound approaches are combined to produce a hybrid algorithm for separable discrete mathematical programs. The hybrid algorithm uses linear programming in a novel way to compute bounds ...

(Massachusetts Institute of Technology, Operations Research Center, 1988) 
The Impact of Processing Time Knowledge on Dynamic JobShop Scheduling
(Massachusetts Institute of Technology, Operations Research Center, 198911)The goal of this paper is to determine if the results for dynamic jobshop scheduling problems are affected by the assumptions made with regard to the processing time distributions and the scheduler's knowledge of the ...

Interpreting Accident Statistics
(Massachusetts Institute of Technology, Operations Research Center, 197107)Accident statistics have often been used to support the argument that an abnormally small proportion of drivers account for a large proportion of the accidents. This paper compares statistics developed from sixyear data ... 
Intuitive solutiondouble techniques for worstcase analysis of some survivable network design problems
(Massachusetts Institute of Technology, Operations Research Center, 2000) 
Inverse Optimization: An Application to the Capacitated Plant Location Problem
(Massachusetts Institute of Technology, Operations Research Center, 197909)Inverse optimization refers to the fact that each time a Lagrangean derived from a given mathematical programming problem is solved, it produces an optimal solution to some problem with a different right hand side. This ...
