> 中文摘要: 提出一种形式化用例分析建模框架,引入类图、用例顺序图、用例状态图、功能规约函数和系统不变式从多个角度为需求建模.通过定义这些视图的形式化语义,为需求的各个方面定义了准确的形式化描述.利用该框架,可以从方法的交互行为规约和功能规约合成描述方法全部行为的全规约;也可以定义用例模型的性质,并通过设计演算中的证明来分析验证这些性质.作为应用,研究了检查用例模型一致性的规则.给出一个实例说明建模框架的可行性.
Abstract:This paper proposes a formal approach to modeling use case which captures requirements from multi-angle views: The class diagrams, the use case sequence diagrams, the use case state diagrams, the specification mapping and the system invariant. By defining formal semantics of those views, each aspect of requirements is given exact formal descriptions. As a result, integrated specification of one method can be built by integrating formal descriptions of its interaction specification and its functional specification. At the same time, properties of use case models can be specified and analyzed through the proof in design calculus. As an application, rules for checking the consistence of use case models are studied. An example to illustrate the feasibility of the proposed method is given.
