Les techniques adaptatives développées dans la littérature requièrent en général la connaissance d'un modèle paramétré du système à commander. Or, en pratiq...

This article describes an extension of the MARKAL energy model, in which the demands for energy services are elastic to their own prices. The new model is c...

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...

The linear Bilevel Programming Problem (BLP) is an instance of a linear hierarchical decision process where the lower level constraint set is dependent on d...

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

In this paper we examine an enumerative solution approach for the directed Rural Postman Problem (RPP) based on transforming the RPP into a version of a Gen...

In this paper, we present a scenario aggregation algorithm for the solution of the dynamic minimax problem in stochastic programming. We consider the case w...

Cylindrical aromatic compounds - fullerenes and hydrocarbons - are about to become highly interesting objects of chemical research. A tubulene (tubular ben...

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

In this article, we examine the evaluation of the economic potentials of various renewable energy technologies. We first argue that traditional evaluation m...

We present a method to compute valid concavity cuts for the linear maxmin programming problem. We consider a primal and a dual approach. In both cases the p...

In this paper we propose a scenario-oriented optimization model and solution algorithm to assess the capacity and the routing of computer networks. The adva...

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 the problem of optimally dimensioning a new geographically distributed computer system that handles all communications between aircraft ...

In this paper we consider the Discrete Lotsizing and Scheduling Problem with sequence dependent setup costs and setup times (DLSPSD). DLSPSD contains eleme...

Le présent article constitue un résumé du mémoire de maîtrise de M. Lavigne, présentement candidat au Ph.D. à l'École Polytechnique de Montréal. L'étude rep...

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...

A new paradigm for cluster analysis is outlined. It is called Sequential Clustering. Given a set <i>O</i> of <i>N</i> entities a best cluster of <i>K</i> ...
