Reliability Assessment of Component Based Software Systems Using Software Component Roles

Software reliability has become one of the main issues for software developers. Aggregating software components into software is a perfect approach to construct software with the maturity of component market. How to analyze software reliability from the reliabilities of its software components and architecture should be answered. However, software in most of the proposed reliability analysis methods is static, while software development is a dynamic process, especially for component-based software, where pervasive process is iterative and incremental. Based on functional abstractions, this paper presents a general model for estimating the reliability of Component Based Software Systems using Role’s of Software Components with Test Suite.
