Reasoning of Feature Models from Derived Features

When using product lines, whose variability models are based on derived features, e.g., Simulink variant objects, the dependencies among the features are only described implicitly. This makes it difficult to verify the mapping of the features to the solution space and to create a comprehensive overview of the feature dependencies like in a feature model. In this paper, an OWL-based approach is presented, which permits the automatic verification of the feature mapping and an automatic feature model synthesis for derived features using OWL reasoning and formal concept analysis.
