基于三维目标建模的需求分析方法

Requirement Analysis Method Based on Three-dimensional Classification Approach of Goal Modeling

面向目标的需求分析方法是需求工程领域研究的热点问题之一。在深入研究目前有代表性的目标分类方法基础上,提出一种不依赖于具体应用领域的、较为系统和完整的目标分类框架和建模方法。该框架从三个角度对目标进行划分,分别将其归类为操作性或非操作性目标,硬目标或软目标以及实现型或维持型目标。这三种分类虽然相互独立,但在实际建模时可以相互补充,形成一个完整的体系,为目标建模提供不同的帮助。在此基础上,还提供了一种目标建模的具体算法,可以较好地完成目标建模任务。

Goal-oriented requirement analysis method is a hotspot in Requirement Engineering research. The urgent affair of goal modeling is to classify goals systematically and integrally. A framework was proposed for classifying goals, in which a goal could be classified as operational or non-operational, ＂hard＂ or ＂＇soft＂, and achievable or maintainable. These three classifications are independent to application domain and can play different roles in modeling by complementing each other. In addition, a modeling algorithm is introduced, which can perform well to guide goal modeling in practice.
