Aircraft sizing, route network design, demand estimation and allocation of aircraft to routes are different facets of the air transportation optimization pro...

This paper provides new results on the application of semidefinite optimization to satisfiability by studying the connection between semidefinite optimizatio...

This paper discusses a unique formulation of en-route flight planning problem in a constrained airspace with the objective of minimizing the total cost while...

We consider the multivariate linear model for multilevel data where units are nested within a hierarchy of clusters. We propose permutation procedures to tes...

Nous présentons une approche efficace pour l'évaluation du risque de contrepartie et le calcul de l'ajustement CVA pour le risque de crédit dans le cas de dé...

In this paper, we propose an empirical study of the centrality of actors in network. The data was collected among publicly available information of the boa...

Increase of bandwidth demand in data networks, driven by the continuous growth of the Internet and the increase of bandwidth greedy applications, raise the i...

We present a matheuristic, an integer programming based heuristic, for the liner shipping network design problem. This problem consists of finding a set of...

Nous étudions des politiques de routage des appels couramment utilisées dans les centres d'appels recevant plusieurs types d'appels et disposant de plusieurs...

Une coloration des arêtes d'un graphe \(G\) est une fonction qui attribue un entier (appelé couleur) à chaque arête de \(G\) de telle sorte que les arête...

L'algorithme RLF (Recursive Largest First) est l'un des plus populaires parmi les heuristiques gloutonnes pour le problème de la coloration des sommets d'un ...

On montre ici que tout semimodule \(M\) de dimension \(m\) sur un anneau idempotent \(S\) ayant une base fortement indépendante peut être plongé dans `...

This paper presents a new method for solving the short-term unit commitment and loading problem of a hydropower system. Dynamic programming is used to comput...

Air-conflict resolution is a bottleneck of air traffic management that will soon require powerful decision-aid systems to avoid the proliferation of delays....

The inventory-routing problem (IRP) integrates two well-studied problems, namely, inventory management and vehicle routing. Given a set of customers to servi...

In many applications, such as metabolomics, data are composed of several continuous measurements of subjects (tissues) over multiple variables (metabolites)....

Constrained blackbox optimization is a difficult problem, with most approaches coming from the mathematical programming literature. The statistical literatur...

Blackbox optimization deals with situations in which the objective function and constraints are typically computed by launching a time-consuming computer ...

A preconditioned variant of the Golub and Kahan (1965) bidiagonalization process recently proposed by Arioli (2013) and Arioli and Orban (2013) allows us to ...

In this article, we propose a general framework for an algorithm derived from the primal simplex that guarantees a strict improvement in the objective after ...
