We study a staffing optimization problem in multi-skill call centers. The objective is to minimize the total cost of agents under some quality of service (Q...

Une livraison plus rapide, des frais d'expédition réduits et une plus grande probabilité de disponibilité des produits sont certains des avantages offerts pa...

We analyze a capital accumulation game in a dynamic version of Cournot duopoly model of complements. In this game, firms' instant profits are discontinuous a...

We review dynamic quality models both in single-agent setup and in a competitive framework. Our objectives are: (1) to give the reader a vantage point on t...

Product recalls are often consequences of quality failures. While such failures are related to a manufacturer's or supplier's design quality, the perceived q...

It is a challenge to sustain cooperation in a finite-horizon dynamic game. Since players generally have an incentive to deviate to their noncooperative str...

This paper introduces the consistent production routing problem in a setting with multiple plants and products. The problem consists in finding minimum-cost ...

Distance metric learning algorithms aim to appropriately measure similarities and distances between data points. In the context of clustering, metric learnin...

Dans cet article, nous introduisons une nouvelle approche pour analyser le processus de diffusion de nouveaux produits qui tient compte de l'hétérogénéité de...

Restless bandits are a class of sequential resource allocation problems concerned with allocating one or more resources among several alternative processes...

The determinantal point process (DPP) provides a promising and attractive alternative to simple random sampling in cluster analysis or classification, for th...

Les algorithmes de partitionnement de données aident à identifier des sous-groupes homogènes en ce sens que les données de chaque groupe partagent des caract...

We address the problem of accelerating column generation (CG) for set-covering formulations via dual optimal inequalities (DOI). DOI use knowledge of the du...

On considère un grand groupe de consommateurs qui peuvent choisir entre deux produits substituables à chaque occasion d’achat. Leur choix est influencé pa...

Dans cet article, nous étudions la concurrence entre marques nationales et marques privées (ou marques de distributeurs) en analysant l’effet de la présence ...

$K$-medoids clustering is among the most popular methods for cluster analysis, but it carries several assumptions about the nature of the latent clusters...

Recommender systems make use of different sources of information for providing users with recommendations of items. Such systems are often based on collabor...

Top-tier customers -that is, those 20% of customers that typically bring in 80% of all profits- are extremely valuable to companies. In the many instances ...

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

Il est bien connu que les consommateurs stratégiques peuvent nuire aux profits des entreprises en retardant leurs achats pour acheter leurs produits à prix r...
