Lower bounds for the capacitated facility location problem based on column generation

Klose, Andreas; Drexl, Andreas - 2001

The Capacitated Facility Location Problem (CFLP) is a well-known combinatorial optimization problem with applications in distribution and production planning. A variety of lower bounds based on Lagrangean relaxation and subgradient optimization has been proposed for this problem. However, in...

Heuristic Concentration and Tabu Search: A Nose to Nose Comparison

Rosing, K.E.; ReVelle, C.S. - 1997

In 1997 two papers_new applying the metaheuristics Tabu Search (TS) and Heuristic Concentration (HC) tothe p-median problem were published in consecutive volumes of the European Journal of OperationalResearch. Here we apply the method of HC some of the data sets which were used for...

Hedonic price equilibria, stable matching, and optimal transport: Equivalence, topology, and uniqueness

Chiappori, Pierre-André; McCann, Robert J.; Nesheim, Lars - 2007

Hedonic pricing with quasilinear preferences is shown to be equivalent to stable matching with transferable utilities and a participation constraint, and to an optimal transportation (Monge-Kantorovich) linear programming problem. Optimal assignments in the latter correspond to stable matchings,...

Pricing the multiple-choice nested knapsack problem

Drexl, Andreas; Jørnsten, Kurt - 2007

The multiple-choice nested knapsack problem (MCKP) is a generalization of the ordinary knapsack problem, where the set of items is partitioned into classes. The binary choice of selecting an item is replaced by taking exactly one item out of each class of items. Due to the fact that the MCKP is...
