Situations where armed forces are now engaged have become more and more varied and complex far away from conventional confrontations. Hence, headquarters have an increasing need of a large variety of scenarios, quickly designed and implemented, in order to anticipate such new kind of situations. This is one of Piovra objectives to provide such kind of model of scenario. Recently, several efforts have arisen seeking similar goal but we choose to keep an high level model usable by end-users. This paper is to present how manage and connect these two levels of modelling: conceptual level for end-user and an operational level in order to perform simulations without platform constraints
