StrataVis : une technique de visualisation graphique orientée modèle

Mastering system engineering means dealing with concepts, methods and tools in order to optimize interactions between multiple components/agents. Despite some focused software solutions (in the conceptual and methodological field), such mastery is not without its pitfalls. In this article, we will put particular emphasis on one of those difficulties: the lack of visual-graphical expressivity of models (referring here to the concrete syntax of modeling languages). Based on a case study, we will describe the features of a new graphical visualization technique called StrataVis that eases model-based system engineering (towards a clarification of inherent complexity of current systems) and requires fewer cognitive efforts from users/model engineers (better visualize and understand the interactions within the systems).
