Description: Introduction: The research “2-Dimensional Multi-Release Software Reliability Modelling considering Fault Reduction Factor under imperfect debugging” was conducted au University of Delhi in 2017. Methods: Here, we develop a software reliability growth model to assess the reliability of software products released in multiple versions under the limited availability of resource and time. The Fault Reduction Factor (FRF) is considered to be constant in imperfect debugging environment while rate of fault removal is given by Delayed S-Shaped model.Results: The proposed model has been validated on a real life four release dataset by carrying out goodness of fit analysis. Laplace trend analysis has been worked out to judge the trend exhibited by the data with respect to change in reliability of the system.Conclusions: A number of comparison criteria have been calculated to evaluate the performance of proposed model relative to only time based multi-release Software Reliability Growth Model (SRGM).Originality: In general, number of faults removed is not same as the number of failures experienced in given time interval so inclusion of FRF in the model makes it better more realistic. A paradigm shift has been observed in software development from single release to multi release platform.Limitations: The proposed model can be used by software developers to make decisions regarding the release time for different versions by either minimizing the development cost or maximizing the reliability and for determining the warranty policies.
