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 first stages of projects, it supports defining the expected system features, when in the later stages it estimates 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. The use of simulation is a specific part of an MBSE approach that is crucial in an efficient project management since it might be the source of high cost and skills needs but also a source of precious knowledge on the future system. Simulation opportunities are numerous, but the project manager must identify the more relevant for their project. This paper aims at documenting the current state of practice in industry on the usage of simulation in MBSE processes. The paper presents a survey conducted amongst French companies, on how they apply MBSE, Verification Validation & Testing VVT, and simulation. The perceived benefits and barriers, and the parameters influencing VVT strategies and the use of simulation are alternately analyzed.
