In this presentation the author proposes how to use the OO (Object-Oriented) modelling techniques in order to represent in a unitary framework phenomena that would otherwise call for different simulation and analysis tools. The proposed ideas are exemplified by addressing and solving: modelling and simulation of large air volumes with a quasi CFD approach, and the reliable representation of control systems. The principles of OO modelling are exploited so as to allow for models of scalable detail level, which permits to tailor the simulation model complexity to any particular study at hand, concentrating on the relevant parts of the system and employing simple (and computationally fast) description of the rest.
