A SVM reliability evaluation model for component-based software systems

The available state-based and path-based reliability models for the component-based software consume high computational cost and suffer from the evaluating complexity in the software evaluation. A SVM reliability evaluation model for component-based software systems (SVMREM) with a low complexity is presented in this paper. The component reliability SVM is performed to optimize the reliability evaluation time consumption. SVMREM has a low evaluation complexity and outperforms the state-based model and the path-based model of the reliability evaluation. Another advantage of SVMREM over the others is its software structure robustness. SVMREM only depends on the component historical reliabilities, which are independent from the software system structure. Based on the theory analysis and experiment results, it shows that the SVMREM reliability evaluating accuracy is acceptable when the software system structure is complex and the complexity of SVMREM is evidently lower than the contrast models.
