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...

Nous avons procédé à des tests afin de vérifier l'applicabilité de la méthode proposée par Langevin et al (1994). Cette méthode a pour objectif la détermin...

Global optimization methods aim at finding the global optimum of a nonlinear and nonconvex function subject to nonlinear and nonconvex constraints. The main...

An overview is given, with new results, of mathematical models and algorithms for probabilistic logic, probabilistic entailment and various extensions. Anal...

Examination timetabling is an important operational problem in many schools, colleges and universities. The authors have developed a computerized examinatio...

Given a set of logical sentences together with probabilities that these sentences are true, the probabilistic satisfiability (PSAT) problem consists, in it...

A count of Kekulé structures for all 1812 distinct fullerene isomers of C₆₀ shows that 20 isomers surpass the count of 12500 for icosahedral C<su...

This paper presents methods to determine the optimal transfer batch sizes of various part types between two machines so as to minimize the sum of the total ...

This paper presents a new approach for planning the dispatching, conflict-free routing, and scheduling of automated guided vehicles in a flexible manufactur...

Crew-Opt is a set-covering method that uses column-generation to produce nearly optimal solutions to crew scheduling problems. We presented this method at t...

We consider the problem of finding a shortest path for a car-like robot (approximated by a point) maneuvering around obstacles. This robot is capable of for...

This survey paper describes the significant advances made in time constrained vehicle routing and crew scheduling problems. In terms of solution methodolog...

This paper examines whether there is a substantial additional payoff to be derived from using mathematical optimization techniques to globally define a set ...

This paper describes strip sequencing models for large scale traveling salesman problems arising in flexible manufacturing operations in two or three discre...

In this paper we explore a new branching strategy for branch-and-bound approaches based on column generation for the vehicle routing problems with time wind...

In this paper we analyze the efficiency of a given robot movement schedule for the case of a flowshop robotic production cell with <i>m</i> different machin...

It is well known that several combinatorial optimization problems can be nicely and readily modeled as an appropriate quadratic 0-1 function to be optimized...

In the Dual Bin Packing Problem (DBP), there are an unlimited number of bins of identical capacity, and unsplittable items of given weights. The aim is to ...

This paper propose a column generation method for optimally solving the rostering problem. Various strategies for accelerating the column generation process...

The purpose of this paper is to formulate and solve an optimization problem arising in the operations of a numerical control machine such as a punch press. ...
