We often observe a phenomenon that stochastic characteristics of the software failure-occurrence time or software failure-occurrence time-interval changes 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...
This paper discusses two-dimensional software reliability measurement technologies, which describe a software reliability growth process depending on two-types of software reliability growth factors: Testing-time and testing-effort factors. From the view point of actual software failure-occurrence mechanism, it is natural to consider that a software reliability growth process depends on not only testing-time...
We propose a two-dimensional SRGM describing a software reliability growth process on the two-dimensional time-space which consists of testing-time and testing-coverage. Our two-dimensional SRGM conserves the theoretical means for the effect of such two-types of the reliability growth factors to the software reliability growth process. And we also discuss a parameter estimation method and a software...
