Covariate Software Reliability Models and Applications
Sponsors: IEEE Boston/Providence/New Hampshire Reliability Chapter
Host: IEEE Boston/Providence/New Hampshire Reliability Chapter
Traditional software reliability growth models enable quantitative assessment of the software testing process by characterizing defect detection in terms of testing time or effort. However, the majority of these parametric models do not identify specific testing activities underlying defect discovery and thus can only provide general guidance on how to incrementally allocate effort. This talk presents a non-homogeneous Poisson process software reliability growth model incorporating covariates based on the discrete Cox proportional hazards model, which explicitly links test activities to defect discovery. Efficient and stable expectation conditional maximization algorithms are derived to estimate the numerical parameters of a model that best characterize the failure data collected during testing. An optimal test activity allocation problem is formulated to maximize defects discovered, so that they can be corrected prior to release. An overview of the Covariate Software Failure and Reliability Assessment Tool (C-SFRAT) will also be provided.
