Détermination d'une période économique robuste dans le cadre du modèle de Wilson

Philippe Vallin (2010)

RAIRO - Operations Research

Similarity:

This paper presents results about the optimal order interval in a context of fuzzy information about inventory management. The classical inventory model is based on well known cost and demand rate. In practice, this accurate estimation is very difficult to obtain, even impossible. Consequently, we propose a solution, not optimal in a classical sense, but allowing to choose an action which is not far from the optimal policy whatever the economic parameters may be. These parameters...

Coloration de graphes : fondements et applications

Dominique de Werra, Daniel Kobler (2010)

RAIRO - Operations Research

Similarity:

The classical colouring models are well known thanks in large part to their applications to scheduling type problems; we describe the basic concepts of colourings together with a number of variations and generalisations arising from scheduling problems such as the creation of school schedules. Some exact and heuristic algorithms will be presented, and we will sketch solution methods based on tabu search to find approximate solutions to large problems. Finally we will also mention...

Choix multicritères dans le risque et variables multidimensionnelles: proposition de méthode et application aux réseaux de transport d'énergie

Bertrand Munier, Nathalie Taverdet-Popiolek (2010)

RAIRO - Operations Research

Similarity:

This paper presents an application of Multiple Attribute Utility Theory on strategic choices concerning energy transportation. The environmental assessment of a network reinforcement strategy is emphasized. Our assessment brings about to consider multidimensional variables in MCDM. However, Multi-Attributed Utility Theory (MAUT) cannot, as a practical matter, manage such variables. We therefore work out a methodology to transform multidimensional variables into unidimensional...

Tarification par des jeux Coopératifs avec Demandes Élastiques

F. Bendali, J. Mailfert, A. Quilliot (2010)

RAIRO - Operations Research

Similarity:

We propose here a pricing Model which is an extension of the Cooperative Game concept and which includes a notion of Elastic Demand. We present some existence results as well as some algorithms. We conclude by discussing this model in the context of some Production and Transportation problems.

État de l'art des méthodes “d'optimisation globale”

Gérard Berthiau, Patrick Siarry (2010)

RAIRO - Operations Research

Similarity:

We present a review of the main “global optimization" methods. The paper comprises one introduction and two parts. In the introduction, we recall some generalities about non linear constraint-less optimization and we list some classifications which have been proposed for the global optimization methods. We then describe, in the first part, various “classical" global optimization methods, most of which available long before the appearance of Simulated Annealing (a key event in this...
