An environment was developed for solving the problem of selecting a proper software reliability model for a given set of software failures. The idea behind the environment developed in this dissertation was to liken a collected set of software failure data to a previous one that proved to fit well with a specified software reliability model. Software failures were assumed to have a two-Parameter exponential distribution with unequal type II censoring. A test criterion was derived for testing Ratio Criterion. The exact distribution of the test criterion was derived. An asymptotic approximation was also obtained and was found to be very close to the exact distribution when the number of failures were more than twenty. Software failure data, available from Data and Analysis Center for Software DACS, were used as the initial group of software failure sets. The environment was then applied, for testing the quality of several software failure sets.
