Probability-based methods for the consideration of detection rates and associated damage sizes have been state of the art in NDT. For structural health monitoring (SHM) systems, the quantification of detection capabilities needs to be addressed to enable the industrial implementation. Due to the fixed mounting of SHM systems on structures, experimentally based investigation is particularly difficult and resource consuming. Therefore, the use of numerical simulations is suggested to generate additional data for probability studies. Within this paper, two methods of model-assisted probability of detection (MAPOD) are presented. For the use case of carbon fibre-reinforced plastics (CFRP) panels, tested with acousto-ultrasonics, a path-based analysis was chosen. After a short description of the underlying numerical models, the used probability-based methods are explained. Their application is shown in detail using a 3D and a 2D model for a CFRP panel.
