模型驱动的系统设计方法应用研究

Application Research on Model-driven System Design Method

本文详细介绍了IBM Rational Harmony系统设计方法在某型飞机IDMS项目中的应用过程。首先,完成IDMS项目的需求分析,输出用户需求与系统需求,采用了DOORS作为需求管理工具,建立了两者的Link关系。然后,完成系统功能分析,输出系统全部用例,采用了RHAPSODY作为系统设计工具,对其中一个用例采用用例图、活动图、顺序图和状态图等进行分析和建模,得到该用例的可执行模型,验证需求。最后,开展系统架构设计,完成系统的初步架构模型。同时,用DOORS和RHAPSODY管理系统设计过程中的知识库。

This paper presents the application of IBM Rational Harmony system design method in IDMS of next generation airplane. It starts with the requirements analysis by DOORS. After the stakeholder requirements and system requirements being produced, the link between them is created. Then, all of the system use cases will be drawn during the system functional analysis. We take one particular use case as an example and draw the use case diagram, activity diagram, sequence diagram and statechart diagram respectively. By doing this the executable model and validation requirements can be derived by RHAPSODY. Finally, the system architecture design and the architecture model are finished. During the development process, the repository database is managed with DOORS and RHAPSODY.
