Abstract Existing feature oriented software product line analysis approaches often pay more attention to fine-grained features other than caring about coarse-grained features, which leads to the lack of support to product line architecture. The concept of feature increment was proposed based on the idea of step-wise refinement. The macroscopical relationships and differences between products were captured and described. Thus, the traceability and maintainability from requirement to product line architecture, and then to software architecture of a specific product can be enhanced. The dependency between feature increments and the composition criteria were described. Then a goal and scenario based analysis process was proposed which is feature increment oriented. The concept and the analysis process were illustrated by a running example of a product line of visual modeling tool. The example shows that feature increment can promote the granularity of software product line analysis and the hierarchy of analysis process in an effective way.

一种面向特征增量的软件产品线分析方法
针对现有的面向特征的软件产品线分析方法大多着眼于细粒度的特征,对宏观特征考虑不多,导致对产品线体系结构支持不足的问题,基于逐步精化的思路,提出特征增量概念,试图捕捉和描述产品线中产品的宏观联系与差异,以增强从需求到产品线体系结构再到单个产品体系结构的可跟踪性和可维护性. 分析了特征增量的依赖关系和组合原则,并给出了基于目标场景的面向特征增量分析过程.结合一个可视化建模工具产品线实例对特征增量和分析过程进行说明.实例表明,特征增量的引入提升了产品线分析的粒度,增强了分析过程的层次性,从而系统且有效的支持产品线的开发活动.
