Formal verification of variant requirements has gained much interest in the software product line (SPL) community. Feature diagrams are widely used to model product line variants. However, there is a lack of precisely defined formal notation for representing and verifying such models. This paper presents an approach to modeling and verifying SPL variant feature diagrams using first-order logic. It provides a precise and rigorous formal interpretation of the feature diagrams. Logical expressions

A case study of a Computer Aided Dispatch (CAD) system variant feature model is presented to illustrate the verification process. Index Terms-Product line, reuse, first-order logic, variants.
