We consider the problem of locating a circle with respect to existing facilities on the plane, such that the largest weighted distance between the circle and...

The objective of the project is to provide dynamic scheduling solutions to two different services, automobile dealerships and dental clinics, in order to hel...

A conjecture of Delorme, Favaron and Rautenbach [DM 257 (2002) 29-38] about the Randic index of a graph, in relation to its order and minimum degree, is ref...

<p>Le système <i>AutoGraphiX (AGX1 et AGX2)</i> permet, parmi d’autres fonctions, la génération automatique de conjectures en théorie des graphes. Nous étud...

We consider two (0,1)-linear programming formulations of the graph (vertex-) coloring problem, in which variables are associated to stable sets of the input...

Ce document valide le cadre conceptuel de logistique inverse de Lambert et Riopel (2004) à l'aide de trois cas industriels d'entreprises oeuvrant dans diffé...

This paper presents a general mixed-norm minisum problem for locating a single facility in continuous space. It is assumed that several transportation modes...

The Team Orienteering Problem (TOP) is the generalization to the case of mul- tiple tours of the Orienteering Problem, known also as Selective Traveling Sal...

Earth observation satellites are platforms equipped with optical instruments that orbit the Earth in order to take photographs of specific areas at the requ...

Given the sets of flights and aircraft of an airline carrier, the fleet assignment problem consists of assigning the most profitable aircraft type to each f...

The paper examines shelf-space allocation and pricing decisions in the marketing channel as the results of a static game played à la Stackelberg between two...

We consider a crew scheduling problem with preferential bidding in the airline industry. We propose a new methodology based on a graph coloring model and a ...

Column generation has proven to be efficient in solving the linear programming relaxation of large scale instances of the Multiple-Depot Vehicle Scheduling ...

Given the flight schedule of an airline, the fleet assignment problem consists of determining the aircraft type to assign to each flight leg in order to max...

The variable neighborhood search metaheuristic is applied to the primal simple plant location problem and to a reduced dual obtained by exploiting the compl...

An infinite-horizon differential game between a manufacturer and a retailer is con- sidered. The players control their marketing efforts and the sales share...

In this paper, a solution approach based on the column generation technique is pre- sented for solving a time-indexed formulation of the total weighted tard...

We consider vehicle routing and crew scheduling problems that involve a lexico- graphic bi-level objective function (for instance, minimizing first the numb...

This paper examines the plant location problem under the objective of maximizing return-on-investment. However, in place of the standard assumption that all...
