Feature modeling is an essential activity for modeling and managing the variability of a software product line. On the other hand, aspect-oriented programming provides effective means for modularizing feature implementation. Although current AOP tools (e.g., AJDT) provide a mechanism for switching aspect modules on and off to configure a product, this becomes infeasible in the context of large-scale product lines with thousands of variations. In this paper, we describe how feature modeling can be integrated with aspect-oriented programming to perform automated product derivation efficiently and effectively in the context of large-scale product lines.
