This paper presents an exact solution approach for the problem of the simultaneous dispatching and conflict-free routing of automated guided vehicles. The ...

This paper formulates and analyzes a pattern search method for general constrained optimization based on filter methods for step acceptance. Roughly, a f...

We define two classes of lower bounds using either one or two simplices for the minimization of a concave function over a polytope. For each of them, a pro...

Cet article propose un modèle d’optimisation des stratégies de maintenance pour une meilleure intégration dans un plan de production préétabli. Le modèle est...

It is well known that the set of correlated equilibrium distributions of a noncooperative game is a convex polytope that includes all the Nash equilibrium ...

This paper presents a new branching strategy that is applied on the cost of a subproblem during the solution of a large-scale linear program by a column gene...

This paper deals with the issue of deforestation, one of the main global environmental problems. We consider two players having different utilities for fores...

Due to the increasing popularity of automated guided vehicles in modern industry and the valuable investment they require, their design and operational issue...

This paper considers the locomotive assignment problem encountered during the planning of the operations of a freight railroad, which consists of providing s...

We examine whether cooperative advertising programs could constitute an effective tool to coordinate competitive marketing channels. While previous studies s...

This paper introduces a new integrated model for the combined day-off and shift scheduling problem (the tour scheduling problem). This model generalizes the...

We explore how a simple linear change of variable affects the inclusion functions obtained with Interval Analysis methods. Univariate and multivariate pol...

This paper provides a framework for logistics decision-making by classifying logistics decisions and highlighting the relevant linkages among them. We focus ...

Corrected Miller-Tucker-Zemlin type subtour elimination constraints for the Capacitated Vehicle Routing Problem are presented.

We present an exact algorithm and three applications of nonconvex quadratically constrained quadratic programming. First, we consider the pooling problem fro...

We develop and analyze parallelization strategies for the Variable Neighborhood Search (VNS) meta-heuristic applied to the <i>p</i>-median problem. The stra...

Albertson (1997) defines the <i>imbalance</i> of an edge (<i>i,j</i>) in <i>E</i> of a graph <i>G</i> = (<i>V,E</i>) as | <i>d_i - d_j</...

The paper analyzes a differential game model of a two-member marketing channel. A manufacturer invests in national advertising with the purpose of improving ...

La majorité des auteurs traitant du problème de design d'implantation d'usine considèrent que la sélection de la configuration du réseau de manutention est f...

Le texte qui suit est l'allocution donnée par le professeur Jacques Desrosiers à la Société Royale du Canada, le jeudi 14 novembre 2002, à l'Université du Qu...
