MODELING THE RELIABILITY OF COMPUTER SOFTWARE.

A major goal in undertaking the study of software reliability is to find or develop original software reliability models. These models are based either on a discrete probability distribution and on a continuous probability density distribution. In addition, a conceptual model based on the readjustment of detected errors at each significant interface point is applied. Software reliability is defined to be the probability that the applications program, together with its supervisory program, database and computing environment, will perform its intended functions at the same time when those functions are needed by the customer.
