We consider a widespread solution method that consists of a column generation approach embedded in a branch-and-bound scheme to solve the multiple depot veh...

We propose a game-theoretic model in which one national-brand manufacturer, acting as a leader, maximizes her own profit and one retailer, selling the natio...

The convex octagon with unit diameter and maximum perimeter is determined. This answers an open question dating from 1922. The proof uses geometric reasonin...

We modify an existing model of climate and economy to address the effect of uncer- tain, threshold events on the choice of optimal emissions control policy....

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

Usual graph classes, such as complete graphs, paths, cycles and stars, frequently appear as extremal graphs in graph theory problems. Here we want to turn t...

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 ...
