【摘要】：特征模型是面向特征的软件开发过程的重要概念和制品,该模型以特征为单位,刻画了领域产品的共性和可变性.在日趋频繁的软件演化过程中,保持特征模型的一致演化,对于支持高效的复用开发和按需配置至关重要.目前,大多数的研究是在需求层面进行共性和可变性分析,对特征模型的研究则集中在对共性和可变性的建模上.但是,由于特征变更在建模过程中存在"涟漪"效应,会导致新的共性和可变性演化.现有的分析方法还无法解决这个问题,会导致丢失一些潜在的产品共性,从而影响复用的效率.提出了一种特征模型扩展和演化分析方法.通过扩展特征关联关系和模型演化元操作,实现对特征变更"涟漪"效应的分析.发现潜在的产品共性,提出重构策略和半自动化的共性提取和特征重构支持方法.该方法还针对典型的配置冲突提出了冲突消解规则和策略.最后,通过案例分析验证了该方法的可用性和有效性.
[Abstract]:Feature model is an important concept and product of feature-oriented software development process. It characterizes the commonness and variability of domain products based on features. In the process of software evolution more and more frequently, it is very important to maintain the consistent evolution of feature models to support efficient reuse development and on-demand configuration. At present, most of the researches focus on the analysis of generality and variability at the requirement level, while the research on the feature model focuses on the modeling of commonness and variability. However, due to the ripple effect in the modeling process of feature change, it will lead to new generality and variability evolution. The existing analysis methods can not solve this problem, which will lead to the loss of some potential product commonalities, thus affecting the efficiency of reuse. A method of extended feature model and evolution analysis is proposed. The ripple effect of feature change is analyzed by extending the relationship of feature association and model evolution meta-operation. After discovering potential product commonalities, refactoring strategies and semi-automated methods for feature extraction and feature refactoring are proposed. This method also proposes conflict resolution rules and strategies for typical configuration conflicts. Finally, the availability and effectiveness of the method are verified by a case study.
