Two ways for bounding <i>n</i>-variables functions over a box, based on interval evalu- ations of first order derivatives, are compared. The optimal Baumann...

The shortest path problem with resource constraints consists of finding the minimum cost path between two specified points while respecting constraints on r...
BibTeX referenceExact and Heuristic Procedures for the Material Handling Circular Flow Path Design Problem
In this study we develop optimization, decomposition, and heuristic procedures to design a unidirectional loop flow pattern along with the pickup and delive...

This paper presents some new heuristics based on variable neighborhood search to solve the vertex weighted <i>k</i>-cardinality tree problem. An efficient l...

We consider the bilevel uncapacitated facility location problem with user preferences. It is known that this model may be reformulated as a one-level locati...

The multiprocessor scheduling problem with communication delays that we consider in this paper consists of finding a static schedule of an arbitrary task gra...
BibTeX referenceDesign of Balanced MBA Student Teams
In some schools and universities, students must sometimes be divided into several teams in such a way that each team provides a good representation of the cl...
BibTeX referenceSelected Topics in Column Generation
Dantzig-Wolfe decomposition and column generation, devised for linear programs, is a success story in large scale integer programming. We outline and relate ...
BibTeX reference
We propose a differential game to study retailer’s allocation strategy of shelf-space shares between the manufacturers of two competing brands. Each manufact...
BibTeX reference
A constant fixed cost of establishing a facility is introduced within the framework of minisum facility location in the continuous space. The solution metho...
BibTeX reference
Linear mixed 0-1 integer programming problems may be reformulated as equivalent continuous bilevel linear programming (<i>BLP</i>) problems. We exploit the...
BibTeX reference
In this exploratory study, a segmentation analysis of a shopping mall’s customers is conducted according to the activities they performed during their visit,...
BibTeX reference
We consider the design of a hybrid opto-electronic network with grooming. We propose a model in which we take into account the fact that grooming traffic req...

A zone-dependent fixed cost is introduced within the framework of minisum location of facilities in the continuous space. An efficient algorithm for determin...
BibTeX referenceAltitude Manpower Planning. An Integrated System that Addresses the Puzzle of Planning a Crew Force
A critical aspect of operating an airline is to continuously maintain adequate staffing levels of qualified crewmembers. The airline must be able to plan sev...
BibTeX reference
The integrated aircraft routing and crew scheduling problem consists in determining a minimum-cost set of aircraft routes and crew pairings such that each fl...
