Ce papier propose une unification de la notation et de la modélisation des réseaux de transports à échelons multiples dans le but d'optimiser le coût global du système. Un modèle de programmation linéaire pour le NE-LRP est analysé et ses limites dans la recherche de solutions optimales...

We charaterize the choice correspondences that can be rationalized by a procedure that is a refinement of the prudent choices exposed in [Houy, 2008]. Our characterization is made by means of the usual expansion axiom and by a weakening of the usual contraction axiom α.

In this paper, we study the relationships between binary lexicographic composition of rationales (see [Tadenuma, 2002]), prudent choices (see [Houy, 2008a]) and refined prudent choices (see [Houy, 2008b]) in the case of multi-criteria decision making. We show that these relationships are linked...
