In this paper we consider discrete qualitative models of ecosystems viewed as collections of interacting living (animals, plants.. .) and nonliving entities (air, water, soil.. .), whose conditions of appearance/disappearance are controlled by a set of formal rules (i.e., processes). We present here a rule-based method allowing to compare...

We consider discrete qualitative models of ecosystems viewed as collections of interacting living (animals, plants..) and nonliving entities (air, water, soil..), whose conditions of appearance/disappearance are controlled by a set of formal rules (i.e., processes). We present here two methods to statically analyze models. The first one is used...

Haïti, pays caribéen, est extrêmement exposé et vulnérable face aux aléas hydro-climatiques. Or, aucune base de données hydro-climatiques exploitable et facilement accessible à la communauté scientifique n'existe. Les seules données existantes sont les 156 séries de pluies mensuelles (1905-2005) et les 70 séries de débits journaliers...
