Abstract:

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.

Key words: GO methodology;reliability analysis;software architecture
