基于特征模型的软件产品线可变性建模方法

Approach of Feature Variability Modeling Based on Feature Model for Software Product Line

特征建模是软件产品线开发中的一项关键活动,对特征可变性和特征依赖的建模是特征模型中最重要的组成部分。阐述了特征模型的元模型,着重讨论了特征可变性建模过程,详细分析了特征可变性、特征之间关系、特征依赖类型的识别方法和使用特征依赖矩阵的表示方法。在此基础上,还通过一个库房监视系统应用软件的产品线可变性建模实例验证了该方法的有效性。

Featrue modeling is a key activity for development of software product line. Feature variability model and feature dependency model are the most important parts in a feature model. This paper introduced the metamodel of feature models and discussed emphatically the process of feature variability modeling. Then it analyzed the approach to identify the feature variability, the relationship between the features and the type of the feature dependency, and the method of the modeling using the feature dependency matrix. Finally a case study of variability modeling in software product line of the storeroom surveillance system was presented to demonstrate the method.
