问题域的各种特征定义了系统要在其中操作的上下文，从而严重影响其需求。然而，大多数的需求规范并没有考虑上下文属性，也很少有建模符号明确地指定域可变性如何影响需求。在本文中，我们提出了一种方法，使用上下文来建模领域的可变性目标模型。我们讨论了上下文的建模，它们对系统目标的影响的规范，以及上下文可变性的目标模型的分析。该方法说明了一个案例研究。
Various characteristics of the problem domain define the context in which the system is to operate and thus impact heavily on its requirements. However, most requirements specifications do not consider contextual properties and few modeling notations explicitly specify how domain variability affects the requirements. In this paper, we propose an approach for using contexts to model domain variability in goal models. We discuss the modeling of contexts, the specification of their effects on system goals, and the analysis of goal models with contextual variability. The approach is illustrated with a case study.
