Critical analysis of feature model evolution

In software product line development, the feature model is widely used to model various relationships between features including variability of features. Although it has been widely used for a long period of time, the feature model suffers from various problems including limited expression of variability, weak scalability and a lack of scientific principles. To overcome such problems, the feature model has evolved and many variations of the original FODA feature model have been proposed but those problems have been only partially solved. To address this current situation of research on feature models, this paper analyzes what problems have been identified in the past, which of them have been solved and which of them still remain to be solved in the evolution of the feature model.
