需求分析可视化的设计与实现

Visualisation on Requirement Specifications

大型信息系统的需求分析是一个系列建模的过程，模型的质量直接取决于开发者对应用系统知识的理解和提取．为了保证开发的系统有较高的质量，要建立一种合适的机制来保证在建模过程中对应用系统的知识获取、表达和评估工作的正确进行．本文提出了基于动态行为模型，采用可视化技术，对应用系统的需求分析进行评估，使用户更容易理解需求工程的结果，了解将要开发系统的动态行为，避免过早建立原型系统的开销．

The processes of requirement specifications in information systems can be viewed as a sequence of model building activities. The quality of each set of models depends largely on the ability of a developer to extract and understand knowledge about an application domain. This implies that developing an information system requires appropriate mechanisms for “knowledge elicitation”, “knowledge representation” and “knowledge validation” about the modeled application domain. This paper has presented a way of validating the conceptual models by animating information captured from dynamic behavior model. By animation, all of users can understand and inspect the behavior of the system under development as early as possible and there is no expensive for building a prototype system.
