In this paper, we describe a branch-and-price algorithm for the personalized nurse scheduling problem. The variants that appear in the literature involve a ...

In this paper, we describe an algorithm for the personalized nurse scheduling problem. We focus on the deterministic counterpart of the specific problem t...

In this paper, we tackle the aircraft conflict resolution problem under uncertainties. We consider errors due to the wind effect, the imprecision on the airc...

In this article, we tackle the conflict resolution problem using a new variant of the minimum weight maximum clique model. The problem consists in identifyi...

In this article, we develop the two-dimensional positive edge criterion for the dual simplex. This work extends a similar pricing rule implemented by Towhidi...

Air traffic in Europe is predicted to increase considerably over the next decades. In this context, we present a study of the interactions between the costs...

The improved primal simplex (IPS) was recently developed by Elhalaloui et al. to take advantage of degeneracy when solving linear programs with the primal si...
BibTeX referenceComparison of mixed integer linear models for fuel-optimal air conflict resolution with recovery
Any significant increase in current levels of air traffic will need the support of efficient decision-aid tools. One of the tasks of air traffic management i...
BibTeX reference
Air-conflict resolution is a bottleneck of air traffic management that will soon require powerful decision-aid systems to avoid the proliferation of delays....
BibTeX referenceImproved primal simplex: A more general theoretical framework and an extended experimental analysis
In this article, we propose a general framework for an algorithm derived from the primal simplex that guarantees a strict improvement in the objective after ...
