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 reliability assessment measure of our model. Further, we show numerical examples for software reliability analysis by using actual data. Finally, we conduct goodness-of-fit evaluation of our model to the actual data, and see that our model has a better performance than representative one-dimensional SRGMs in terms of mean squared errors.
