摘要
软件产品线领域需求记录了不同软件产品的共性和可变性。在现有需求过程框架下,对产品线需求获取方法与需求分析方法进行了研究,完善了产品线需求可变性的管控机制。以原子需求为视点,提出了利用需求场景获取产品线领域需求的方法;通过原子需求构建的产品需求矩阵与用例需求矩阵,分析得出需求资源的可变性关系;通过可变性关系的形式化描述,建立产品线可变性用例模型。
Software product line (SPL) domain requirements record the commonality and variability of different software products. Through analyzing the process of requirements, the method of how to elicit and analyze variant SPL requirements is improved, and the control mechanism of variability in SPL is enhanced. The scenario-based method elicited domain requirements through the viewpoint of primitive requirement (PR). The commonality and variability of the SPL requirements is ascertained by applying the PR-context matrix and PR-use case matrix. The method to modet variant requirements is also provided by the formalization expresses of requirement de- pendence and constrain.
