Abstract: Reliability and availability have long been considered as critical metrics of high quality software systems. However, as plenty of research efforts have been devoted into the field of software reliability, only a little has been documented in the aspect of software availability. In the meantime, traditional ways of analyzing software quality often ignores the impact of environmental factors, such as software maintenance and software security issues. Realizing the importance of software availability to software quality study, this thesis first focuses on the modeling of software availability and some application extensions. Then the model is further extended to analyze the availability issues of fault-tolerant software systems, followed by a quality analysis of distributed software system considering malicious software attack. Quantitative modeling and results of the research in this thesis may provide theoretical support for industrial practice.
