摘要
用例分析技术通过用例、执行者以及用例之间的关系来描绘系统外在可见的需求情况。文中介绍了用例分析技术易于软件开发人员与用户之间开展沟通与交流的特点,阐明了用例分析技术有助于提高需求分析的效率和质量。通过高炉开炉装料系统的开发实践,从执行者、用例和用例规约三方面,探讨了用例分析技术的建模步骤,从而描述了一种使用用例分析技术开展需求建模的有效的实现方法。
Use case analysis technology describes the visible and external requirement of the system through use cases, actors and the relation among the use cases. The characteristics of use case analysis technology have been introduced. It expounds that use case analysis technology contributes to improve the efficiency and the quality of requirement analysis. And the steps of use case analysis technology modeling have been expounded from the aspects of actor, use ease and use ease specification by adopting use case analysis technology to create model of the charging of blowing - in blast furnace system. The effective methods of requirement modeling by means of use case analysis technology have been explored.
