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...

In the last two decades, various studies developed static and dynamic game theory models to demonstrate that the efficiency of marketing channels can be rai...

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...

Most examples of cycling in the simplex method are given without explanation of how they were constructed. An exception is Beale’s 1955 example built around...

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...

Column generation is one of the most successful approaches for solving large scale linear programming problems. However, degeneracy difficulties and long-ta...

Column generation has become a powerful tool in solving large scale integer programs. It is well known that most of the often reported compatibility issues ...

Several upper bounds on the largest Laplacian eigenvalue of a graph <i>G</i>, in terms of degree and average degree of neighbors of its vertices, have been ...

This paper considers a shift scheduling problem that includes different forms of flexibility in terms of shift starting times, break lengths and break plac...

Une étude du transport de roses coupées, en collaboration avec la plantation Mira- flores évalue l’exportation de Bogotá (Colombie) vers Miami (USA), port d...

La localisation d'un site d'approvisionnement pour minimiser les coûts d'opérations est une problématique industrielle courante. Les variables classiques co...

Several variants and generalizations of the Or-opt heuristic for the <i>Symmetric Traveling Salesman Problem</i> are developed and compared on random and pla...

The objectives of this paper are twofold; we first demonstrate the flexibility of the mesh adaptive direct search (MADS) in identifying locally optimal algo...
