Generally, it is pretty clear and widely accepted that the human actor plays a significant role in any simulation project ? although in recent years some authors proclaimed a revival of human-free simulation at least related to distinct parts of a simulation study. Therefore, the paper aims to provide an overview on needs and challenges in model-user interaction as well as on approaches, methods and tools to support the user in bringing in his/her knowledge in all phases of a simulation project from model building via understanding a model and using it for experimentation to correctly interpreting simulation outcome. Furthermore, barriers and problems hindering a simulation stakeholder in sharing his/her knowledge are identified and approaches to access and extract such knowledge are discussed in order to avoid inefficiency and failure in future projects.
