Advances in software product quality measurement and its applications in software evolution

The main results presented in this work, a synopsis of the connected PhD dissertation, are related to software product quality modeling and measurement as well as to the application of the newly proposed methods, tools and techniques in software evolution. All the novel theoretical results and models were thoroughly validated via empirical case studies and successfully applied in practice. The thesis result statements can be grouped into three major points: (i) system-level software quality models; (ii) source code element-level software quality models; (iii) applications of the proposed quality models. Some of the methods and tools presented in the thesis have been utilized in Hungarian and international R&D projects as well as by the industrial partners of the Software Engineering Department of the University of Szeged.
