We define two classes of lower bounds using either one or two simplices for the minimization of a concave function over a polytope. For each of them, a pro...

Consider <i>N</i> entities to be classified (e.g., geographical areas), a matrix of dissimilarity between pairs of entities, a graph <i>H</i> with vertices a...

Cet article propose un modèle d’optimisation des stratégies de maintenance pour une meilleure intégration dans un plan de production préétabli. Le modèle est...

Pseudorandom sequences are one of commonly used test signals in system identification (Ljung, 1999; Soderstrom and Stoica, 1989). In this report, we first ...

Engle and Russell's autoregressive conditional duration (ACD) models have been widely used to model financial data that arrive at irregular intervals. In t...

It is well known that the set of correlated equilibrium distributions of a noncooperative game is a convex polytope that includes all the Nash equilibrium ...

The objective of this paper is to provide a game-theoretic interpretation of joint implementation in environmental projects. We consider a two-player game an...

This paper presents a new branching strategy that is applied on the cost of a subproblem during the solution of a large-scale linear program by a column gene...

This paper deals with the issue of deforestation, one of the main global environmental problems. We consider two players having different utilities for fores...

Due to the increasing popularity of automated guided vehicles in modern industry and the valuable investment they require, their design and operational issue...

This paper considers the locomotive assignment problem encountered during the planning of the operations of a freight railroad, which consists of providing s...

Convex feasibility problem in general is a problem of finding a point in a convex set contains a full dimensional ball and is contained in a compact convex ...

We examine whether cooperative advertising programs could constitute an effective tool to coordinate competitive marketing channels. While previous studies s...

We present a novel exact solution method for the centralized network design problem on directed graphs. The problem is modelled as the well-known graph theo...

Lattice rules are quasi-Monte Carlo methods for estimating large-dimensional integrals over the unit hypercube. In this paper, after briefly reviewing key i...

This paper explores new ways of constructing and implementing random number generators based on linear recurrences in a finite field with 2<sup><i>w</i></sup...

This paper introduces a new integrated model for the combined day-off and shift scheduling problem (the tour scheduling problem). This model generalizes the...

We explore how a simple linear change of variable affects the inclusion functions obtained with Interval Analysis methods. Univariate and multivariate pol...

We describe a tabu search algorithm for the vehicle routing problem with split deliveries. At each iteration, a neighbour solution is obtained by removing a ...

This paper provides a framework for logistics decision-making by classifying logistics decisions and highlighting the relevant linkages among them. We focus ...
