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...

Generalized logical analysis aims at modelling complex biological systems, especially the so-called regulatory systems like genetic networks. The main feat...

This article describes a tabu search heuristic for the <i>Dial-a-Ride Problem</i> with the following characteristics. Users specify transportation requests ...

The convergence theory of generalized pattern search algorithms for unconstrained optimization guarantees under mild conditions that the method produces a li...

The paper identifies conditions under which time-consistency and agreeability, two intertemporal individual rationality concepts, can be verified in linear-s...

We consider a new variant of constrained shortest path problem, where the constraints come from a set of forbidden paths (arc sequences) that cannot be part...
