A new path based reliability approach for estimation of reliability of Component Based Software Development

چکیده
One of the motivations for stipulating software architectures explicitly is the use of high intensity structural design information for improved control and prediction of software system quality attributes. Gradually software applications are mounting more complex and with more stress on reuse. The focus of this paper is to provide an outline for the state of the art of Component Based Systems reliability estimation and to present an approach for determining the reliability of component-based software architectures. The proposed model in this paper provides software system dependability in term of the reliability of different execution paths and the usage ratio of each component. The reliability of a component most powerfully depends on its environment. Therefore, we promote a reliability model parameterized by mandatory component reliability in a deployment perspective. Keywords-Software reliability, Probability distribution, weighted mean, Component reliability, componentbased software development.

On the estimation of reliability of a software system using reliabilities of its components
We report an experiment to evaluate a method, known as Component Based Reliability Estimation (CBRE), for the estimation of reliability of a software system using reliabili-ties of its components. CBRE involves computing path reliability estimates based on the sequence of components executed for each test input. Path reliability estimates are averaged over all test runs to obtain an estimate of...

In this paper, a self-healing approach for smart distribution network is presented based on Graph theory and cut sets. In the proposed Graph theory based approach, the upstream grid and all the existing microgrids are modeled as a common node after fault occurrence. Thereafter, the maneuvering lines which are in the cut sets are selected as the recovery path for alternatives networks by making ...
متن کاملA Heuristic Model for Estimating Component-Based Software System Reliability Using Ant Colony Optimization
Most software reliability models for component-based software systems (CBSSs) depend on either the system architecture or component reliability and glue code reliability. It is important to optimize the usage of paths to obtain more accurate estimates of CBSS reliability. By using bio-inspired optimization techniques that are currently being developed, we can find the value of the most-used pat...
