Vers un modèle de prédiction de la qualité du logiciel pour les systèmes à objets

Modularity has been considered an important software product quality criterion. A software product is considered modular if its components exhibit a high cohesion and its components are weakly coupled. A module has high cohesion if all of its elements are related strongly. In the particular context of object oriented applications, there are different types of coupling between classes. Measuring...

Modèle de radiation et modèle gravitaire - Du formalisme à l'usage

Simini, González, Maritan et Barabási recently proposed a “universal model for mobility and migration patterns” : the radiation model. They compare the radiation model to the gravity model and conclude that the latter suffers important theoretical inconsistencies and systematic predictive discrepancies. By confronting both models, they address crucial issues about formalisms and usages of spati...

De la simulation de l'embroussaillement à un outil d'aide à la gestion de l'espace - un modèle de transformations de l'espace

Taking into account interactions and simulating dynamics, the MSA are adapted to modelize complex systems. In case of land-use management, the caracteristics of the space and the perception of actors are important. We formalize the concept of spatial agregation and generalisation and we implement generic spatial entities in a simulation platform. The ForPast model uses it, applied to the contro...

Suppose a decision maker (DM) has partial information about certain events of a -algebraA belonging to a set E and assesses their likelihood through a capacity v.When is this information probabilistic, i.e. compatible with a probability? We consider three notions of compatibility with a probability in increasing degree of preciseness. The weakest requires the existence of a probability P on A s...
