Modeling Software Product Line (SPL) features plays a crucial role to a successful development of SPL. Feature diagram is one of the widely used notations to model SPL variants. However, there is a lack of precisely defined formal notations for representing and verifying such models. This paper presents an approach that the authors adopt to model SPL variants by using UML and subsequently verify them by using first-order logic. UML provides an overall modeling view of the system. First-order logic provides a precise and rigorous interpretation of the feature diagrams.
