基于场景元模型的软件产品线追踪方法

针对软件产品线需求追踪方法进行了研究，基于软件产品线领域需求分析、设计、实现三个阶段的信息传播，提出了一种基于场景元模型的多层次软件产品线追踪模型，完整描述了追踪信息变化的整体框架；建立了需求—用例追踪矩阵、用例—动作追踪矩阵、动作—构件追踪矩阵；根据矩阵运算，描述了具体追踪实现过程，通过一个ATM案例验证了该方法对于软件产品线领域需求获取以及需求变更等问题的解决有较好的效果。

Approach of tracking for software product line based on scenario metamodel

This paper studied methods for tracking software product lines, and based on demand analysis, design and realization of information transmission in the domain of software product line, proposed a multi-layer software product line tracking model based on scenario metamodel, and described of the overall framework for tracking information changes completely. It established requirements-use case tracking matrix, use case-action tracking matrix and action-component tracking matrix. According to matrix operation, it described the implementation process of tracking, and used an ATM case to verify that the method has a good effect on requirements acquisition in software product line and difficulty in requirement change.
