基于UML用例图与顺序图模型的操作剖面构造

Operational Profile Development Based on UML Use Case Diagram and Sequence Diagram Model

探讨了由面向对象用例模型构造操作剖面的可行性 ,结合一个实例 ,详细介绍基于统一建模语言UML(UnifiedModelingLanguage)的用例图和顺序图构造操作剖面的具体方法 ,并对基于UML用例图和顺序图构造操作剖面方法的有效性进行了分析 .结果表明 ,将操作剖面构造与软件系统建模相结合 ,可大大简化构造过程 。

A new approach for developing operational profile used in software reliability engineering was presented, based on UML (Unified Modeling Language) use case diagram and sequence diagram model. With the approach, the operational profile developing process was reduced to three main steps. To compare with Musa's method, a subset of a telephone system was used as an example to demonstrate the ability of our approach to construct operational profile. The result proved that this approach was not only equivalent to Musa's, but also more efficient and more tractable.
