Abstract: The present paper describes a methodology based on graph theoretic system approach for the reliability analysis of Component Based Software System (CBSS). It also supports optimum selection of structure/architecture based on reliability. A detailed procedure for the reliability analysis of CBSS is suggested through a reliability function. Coefficients of similarity or dissimilarity, which compare two CBSS structure/architectures based on reliability, are developed. The quantitative measure of the reliability of a system through the reliability index is proposed in this paper. The paper also identifies the impact on reliability based on heterogeneous architecture styles. The reliability index aids in the identification of an optimum structure/architecture of the system based on reliability and also helps in system identification, analysis and comparison. Finally illustrated examples are given to validate and show the effectiveness of the proposed approach.
