Reliability Bounds Prediction of COTS Component Based Software Application


Tirthankar Gayen, R. B Misra


Vol. 8  No. 12  pp. 219-228


In this paper a unique methodology based on the execution scenario analysis of the COTS component based software application has been formulated to help the developers and integrators to regain some control over their COTS component based software application systems by predicting the upper and lower bound on the reliability of their application systems. At the component level the CFG (control flow graph) of the component and at the application level the CDG (component dependency graph) of the application are explored to identify all possible execution scenarios. The maximum and minimum reliability values are obtained by evaluating and comparing the reliability values obtained from various execution scenarios.
