Abstract : Nowadays, simulation technologies are becoming indispensable to support the design process, and notably during the verification and optimization phases. However, when building a simulation architecture that has to provide the systems architects with answers, simulations architects have to correctly specify the corresponding models required. In a MBSE concept, we propose to extend the concept of model of intention, to verify the specification of these models, to model suppliers by providing them with a Model Request Package. Models of Intention will allow an executable verification of the simulation architecture before the integration of the final models of realization.
