摘　　要： 特征模型作为捕获领域需求的重要模型已被现阶段的主流领域工程方法所接受,但这些方法缺乏对特征模型组织框架的细致研究和说明,在一定程度上导致了特征模型在表现形式上的冗余性和混乱性,也使得领域分析人员在实践中很难有效地进行领域建模活动,从特征模型的基本组织结构、变化性的表现方式和限制机制、变化性 的绑定时间等方面对特征模型的组织框架及剪裁机制进行了统一、抽象的描述,在考察服务、周例(use case)、功能、行为特点等不同类型的特征及其相互关系的基础上,给出了一种特征模型的具体形式,并结合具体的领域,对其建模过程进行了详细论述。此项研究对于领域建模活动的成功实施具有一定的指导作用。 The feature model has been widely adopted as a domain requirements capturing model by most of the current domain engineering methods. But these methods lack a well formatted framework for the feature models which they use. This has led to the redundancy and confusion in feature model representation between different domain engineering methods, and has made domain analysts difficult to built feature models effectively in practice. In this paper, a uniform framework of feature model is presented from the aspects of basic structure, variability representation and constraint mechanism, and variability binding time. A concrete form of this abstract framework is also given based on the different type of features existing in requirements (service, use case, function, and behavior characteristic), and the relationship among them. Then, combining with a real software domain, the modeling process of the feature model is discussed systematically. This approach will be beneficial to successful domain modeling practices.
