TWO-DIMENSIONAL SOFTWARE RELIABILITY MODELING WITH RANDOMNESS OF EFFECT OF CHANG-POINT
We often observe a phenomenon that stochastic characteristics of the software failure-occurrence time or the software failure-occurrence time-intervals change notably in an actual testing-phase of a software development process.The testing-time when such phenomenon is observed is called change-point.It is said that the effect of change-point on the software reliability growth process influences accuracy for software reliability assessment based on a software reliability growth model (SRGM).This paper discusses a two-dimensional SRGM, in which the software reliability growth process is assumed to depend on the simultaneous testing-time and testing-effort factors, with the effect of the change and the uncertainty of the magnitude of the effect on software reliability growth process at change-point for more plausible two-dimensional software reliability assessment.Finally, we show examples of the applications of software reliability measurement based on the proposed model by using actual data.
