摘要
GO法是一种系统可靠性分析方法,可将GO法应用到软件体系结构的可靠性分析中。根据软件体系结构自身的特点及构件之间的关系,分别建立了软件体系结构六种基本结构的GO模型,并进行了定量GO运算。通过一个实例,说明了应用GO法对软件体系结构的可靠性进行分析的全过程。实践表明:运用定量GO运算能够方便地计算出整个软件体系结构的可靠度,通过定性GO分析还可评估各构件及连接件的重要性,对后期系统的设计与开发具有一定的指导意义。
The GO methodology is a method of system reliability analysis, which is applied in the reliability analysis of software architecture. Based on the characteristics of software architecture and the relationship among components, we build GO models with six basic structures, and conduct quantitative GO operations. We demonstrate the whole process of reliability analysis of software architecture using the GO methodology through an example. The practice indicates that the reliability of software architecture can be calculated through quantitative GO operations. The importance of components and connectors can be evaluated via qualitative GO analysis, which has a certain guiding significance for the design and development of the system.
