In recent years, there have been several important algorithmic developments for the traveling salesman problem and the vehicle routing problem. These inclu...

The multisource Weber problem is to locate simultaneously <i>m</i> facilities in the Euclidean plane in order to minimize the total transportation cost for ...

We consider a weekly locomotive scheduling problem encountered at Swedish State Railways. The objective is to find cyclic locomotive schedules, which minim...

A hypergraph <i>H=(X,E)</i> is <i>nested</i> if its edges are pairwise disjoint or included one into the other. The <i>nesticity</i> of <i>H</i> is defined...

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

This paper describes the operational airline crew scheduling problem and represents a first published attempt to solve it. This problem consists of modifyin...

Given a set of entities, Cluster Analysis aims at finding subsets, called clusters, which are homogeneous and/or well separated. As many types of clusterin...

This paper formulates the problem of maximal closure on a graph with resource constraints as an integer programming problem with binary variables, and propo...

La méthode de génération de colonnes est couramment utilisée pour résoudre des problèmes d'optimisation de grande taille. En pratique, on observe fréquemmen...

We study both the continuous and discrete problems of maximizing the product of two linear functions subject to all variables being between 0 and~1. We fir...

Cet article présente une étude comparative des algorithmes de flot maximum pour la résolution du problème de fermeture maximale sur un graphe. Plusieurs ap...

It is shown that the anytime deduction procedure for probabilistic entailment of Frisch and Haddawy does not have the correctness property when the probabil...

Clustering with a criterion which minimizes the sum of squared distances to cluster centroids is usually done in a heuristic way. An exact polynomial algori...

We study the problem of finding a shortest collision-free path for a point car-like robot maneuvering around polygonal obstacles in a room bounded by a poly...

The paper is concerned with sustainable cooperation in a vertical two-member channel of distribution over an infinite planning horizon. Sustainable intertem...

We study the problem of minimizing the peak load in single-command cycle shared storage policies. The peak load is the maximum of the daily material handlin...

Diverses classes de modèles permettant la génération de solutions pour des problèmes d'implantations d'usines sont décrits. La description de chacune des c...

We consider a model for communications network design that includes the optimal location of switches (of which there are several types) and the design of th...

Two new path problems in graphs are studied: MINRANGE, i.e., find a path from a vertex <i>s</i> to a vertex <i>t</i> with the smallest possible range of a...

In this paper a new approach for the facility layout problem is presented. This approach combines genetic algorithms with linear programming to design the ...
