Approach of feature dependency modeling for software product line
一种面向产品线的特征依赖建模方法

Feature dependency modeling describes the model of mutual constraints among features. It is an essential activity for development of software product line. This paper introduced local dependency and global dependency of feature. With analyzing relationship of feature dependency, an approach of feature dependency modeling was proposed. 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.
