The Atlantic thermohaline circulation (THC) is an important component in the climate system because it strongly influences conditions in the North Atlantic ...

Chemical graphs, as other ones, are <i>regular</i> if all their vertices have the same degree. Otherwise, they are <i>irregular</i> and it is of interest to...

This paper presents an enumeration algorithm based on dynamic programming for optimally solving the fleet management problem in underground mines. This probl...

We consider a game where players face environmental constraints. We derive and compare noncooperative, cooperative and umbrella scenarios. In the latter, the...

This paper presents an overview of the modeling approaches that are used to represent, understand and control the interactions between the economy of a regio...

Dantzig-Wolfe decomposition and column generation, devised for linear programs, is a success story in large scale integer programming. We outline and relate ...

The fleet management problem discussed in this paper consists in assigning the best routes to a set of vehicles in an underground mine haulage network. The h...

This paper presents two solution approaches for taking into account the displacement mode (forward or in reverse) of vehicles during the solution of the shor...

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

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

This paper describes a real-time fleet-management system for an underground mine. Dispatching, routing, and scheduling are handled simultaneously, taking...

This paper presents a solution approach for routing a fleet of automated vehicles on haulage networks having one-lane bidirectional road segments. The solu...

Generalized logical analysis aims at modelling complex biological systems, especially the so-called regulatory systems like genetic networks. The main feat...

This paper describes a method for evaluating the kinetic constants in a rate expression for catalytic combustion applications using experimental light-off c...

This paper deals with dispatching systems in open-pit mines. It illustrates the different strategies that exist for solving the dispatching problem and ana...

The operating schedule problem in open-pit mine can be associated with the problem of maximal closure on a graph. In the literature, the Lagrangian relaxati...

This note determines a rule to share a surplus gained when two countries or regions agree to coordinate their policies to reduce downstream pollution. An in...

The paper considers two neighboring countries wishing to make a joint effort to control pollution emission. We use a differential game model that includes ...

We study the problem of allocation over time of total cost incurred by countries in a cooperative game of pollution reduction. We compute the characteristi...

We study empirically the topology of the local minima of the 3-SAT problem. In particular, we analyze the size of the plateaus, their altitude, their attrac...
