Feature Dependency Modeling for Software Product Line

Feature dependency Modeling describes model of mutual constraints among features. It is essential activities for development of software product line. This paper introduces local dependency and global dependency of feature. With analyzing relationship of feature dependency, we propose an approach of feature dependency modeling. It not only provides specification of local dependency such as decomposition and generalization, but also provides global dependency modeling such as configuration dependency, operational dependency and impact dependency. Finally a case study of feature dependency modeling in air-condition controlling software product line is presented to demonstrate our method.
