By using these concepts we outline the research devoted to modelling and managing behaviours of Collective Beings, emergent from the same agents simultaneously interacting in different ways. Collective Beings are systems in which each interacting component can simultaneously belong to different systems. The DYnamic uSAge of Models (DYSAM) is then introduced as a tool to model and manage Collective Beings, by using different disciplinary types and levels of description.
