| Abstract: | Fault Tree Analysis (FTA) is a widely used method for assessing the reliability and safety of the system. However, the increasing structural complexity of fault trees can make them difficult to interpret, particularly when models are reused or modified by others. To address this challenge, this study explores the understandability of fault trees by identifying complexity-related metrics that influence the ease with which a model can be interpreted. Drawing on research from related fields, particularly business process modeling, we adapt a set of candidate metrics. These metrics were then applied to a sample of fault tree models, and an Exploratory Factor Analysis (EFA) was performed to uncover latent dimensions underlying perceived complexity. The resulting factor structure provides a foundation for a systematic framework to assess and potentially improve fault tree understandability. This work contributes toward more interpretable safety models. |
