The achievement of a new project management education simulation program concerning a underground water cleaning-up case study, allowed us to perform simulation sessions for eight teams of students. Considering simulation results, the validation of credibility and functionality criteria concerning this new simulator Amise, indicates that the students have generated relevant cleaning-up scenarios consistent with the real case study. The simulation program can then be considered as a relevant tool to study the behaviour of its components in a project management context, especially the simplified ground water model. To verify that a ground water model is appropriate to the project needs, we introduce two evaluation criteria : the modelling quality and the input knowledge. The input knowledge is considered as a precision and quantity indicator of the model input data. For each simplified ground water model achieved by the students during simulation sessions, these criteria are quantified through an analytical hierarchy process. Using these values, we represent, on a graph, the evolution of the modelling quality of the underground model used in the simulation program according to the knowledge input in the model by the students. On this graph, we can define three areas characteristic of the impact that can have the input knowledge on the modelling quality. Considering the insufficient number of available simulation sessions results, we can not yet confrrm the validity of this graph. However, this study allows to verify the coherence of this approach as a method to analyse a model using a project management education simulation program.
