Due to the diversity of extended transaction models, their relative complexity and their lack of formalization, the characterization and comparison of these models become delicate. Moreover, these models capture only one subset of interaction which can be found in the spectrum of the possible interaction. In front of this established fact, the framework(More)

Bien que ces tâches représentent (selon les spécialistes du domaine) à peu près les trois quart du projet décisionnel [13], les outils du marché n’offrent pas(More)
