Modelling the successive software release time of S-shaped model with imperfect debugging

Software Reliability is a significant attribute of the software quality, so attaining reliability is a vital subject for the evaluation of any software product. Software Reliability Growth model defines the phenomenon for fault discovery in testing phase of the development process of a software. Software Reliability models being a contrivance of Software Reliability Engineering (SRE), focuses on engineering methodology and techniques that can be used for the quantitative assessment of the software product, develop test results, schedule timely status, and observe the variations in software reliability performance [9]. Due to extreme competitions, the software companies are approaching with multiple upgrade versions of the software to endure the competition, thus analysing the software in the functional stage. This paper presents a continuous successive releases time modelling based on S-shaped SRGM with imperfect debugging.
