Validation of an Exponentially Decreasing Failure Rate Software Reliability Model

Abstract

The purpose of this thesis was to determine the validity of a software reliability estimation model proposed by the Air Force Operational Test and Evaluation Center (AFOTEC). During the last forty years of the computer era, the demand for software has been growing at a rate of twelve percent per year; and about fifty percent of the total life cycle cost of a software system is attributed to software fault increases dramatically as the life cycle progresses. It was statistics like those discussed above that prompted this research. The research had these specific objectives: the first was ascertaining the soundness of the model;s intrinsic logic. The second objective was to run the model with actual failure data to measure the validity and correlation of the data with the model. The final objective was to determine the assumptions required to operate the model. (KR)
