A government wishes to accelerate the adoption of a new technology in order to gradually replace an older one. The new technology is manufactured by a mono...

We study links between the bilevel linear and linear mixed 0-1 programming problems. A new reformulation of the linear mixed 0-1 programming problem into a...

In this paper we derive lower bounds on the size of a minimum cover of a graph <i>G</i> by computing packings of edges, odd cycles and cliques of <i>G</i> o...

In this paper we tackle the problem of jointly finding the optimal location of the ATM switches, the topology of the backbone and local access networks, the...

Multiobjective decision making problems occur in a variety of transportation planning settings. These are often ill-defined and may involve several players...

The <i>p</i>-maxisum dispersion problem consists of locating <i>p</i> facilities at vertices of a network in order to maximize the sum of the distances betw...

Splitting a tree is defined as removing all edges of a chain and disconnecting one from the other edges incident with that chain. Splitting a forest is simu...

Local descent methods typically employ a single neighbourhood structure to conduct the search around a candidate solution. In this paper, we propose a metho...

In 1986, Carter published a survey of papers on practical examination timetabling. In the intervening years, there have been a number of new applications, ...

Nous nous penchons sur la modélisation et le traitement de problèmes d'entreposage du type partagé. Nous supposons que l'entrepôt est à charge unitaire et q...

Cluster Analysis is at the crossroad of many disciplines, and has numerous and diverse methods and applications. Mathematical Programming (together with gra...

Several heuristic methods have been developed to solve the location-allocation problem in continuous space. Typically, these algorithms attempt to move in d...

In this paper we consider the daily aircraft routing and scheduling problem (DARSP). It consists of determining daily schedules which maximize the anticipat...

We present a recent optimization approach that can be applied equally to aircraft routing, crew pairing generation and bidding/rostering problems arising in...

L'entreposage partagé, contrairement à l'entreposage dédié, permet qu'un emplacement du palettier reçoive des unités de différents produits ou classes de pr...

The purpose of this paper is to develop optimal tool partitioning policies and strip sequencing strategies for a class of flexible manufacturing problems su...

This paper reviews genetic algorithms and evolution systems and describes implementation of an evolution system to solve the QAP. Extensive search to select...

There are several routing and scheduling problems faced by airline companies, notably, aircraft scheduling, pairing generation and crew bidding and rosterin...

The multi-source Weber problem requires locating <i>m</i> new facilities in continuous space in order to minimize a sum of transportation costs to <i>n</i> ...

Ce document porte sur la fonction entreposage en général et sur les méthodes de rangement en particulier. Il est divisé en deux chapitres. Dans le premier c...
