Abstract : Model-based systems engineering (MBSE) has been proposed as an approach to manage the complexity of modern product development through the continuous use of models. The use of model simulation is a core principle of the MBSE approach. In the early stages of projects, it for example supports defining the expected system features, when in the later phases it can be used to estimate the dynamic behavior. Simulation is pushed to obtain results earlier and cheaper than with testing and prototyping. However, the development of simulation can be a very tedious and expensive task. Simulation opportunities are numerous, but the project managers must identify the more relevant for their project. This paper aims at documenting the current state of practice on the usage of simulation in MBSE processes. Then it aims at exploring decision support opportunities for simulation use in MBSE projects. The paper presents a survey conducted amongst French companies, on how they apply MBSE, Verification Validation & Testing (VVT), and simulation. The perceived benefits, barriers, and the parameters influencing VVT strategies, and the use of simulation are alternately analyzed. The results of the survey are used to propose a Prioritization of Simulation Efforts Methodology (PSEM) to assists managers in choosing the right functions, or systems' elements to be simulated.
