Guenther Ruhe, Professor Of University Of Calgary, Canda, Visited Institute Of Software Chinese Academy Of Sciences

Date: June 6, 2014.

In the morning of June 6th, Guenther Ruhe, the Professor of University of Calgary, Canda, visited the Institute of Software Chinese Academy of Sciences (ISCAS) and gave a lecture titled ˇ°Theme-based Release Planningˇ±.

In his presentation, Professor Ruhe gave a brief introduction into traditional Release planning, and pointed out that traditional planning looks at the sum of the values of individual and potentially isolated features. As an alternative idea, theme-based release planning will be better in some ways.


Professor Ruhe proposed an analytical approach to detect themes from a given set of feature dependencies. On top of an existing release planning methodology called EVOLVE II, the proposed approach applies clustering performed on a feature dependency graph. The release plans generated from such an approach are a balance between two goals: (i) considering the values of individual features, (ii) detecting and utilizing synergy effects between semantically related features.

During the question-and-answer session, Professor Ruhe provided detailed answers to each questioner according to his own research and experience.


Professor Ruhe holds an Industrial Research Chair in Software Engineering at University of Calgary. This is a joint position between department of Computer Science and department of Electrical and Computer Engineering. Professor Ruhe is proud to lead a research team whose primary aim is to establish and demonstrate scientific excellence in the area of software engineering decision support and to collaborate with industry. The area of research is highly relevant, because software and systems decisions are of paramount importance for success in business today. He was a Principal Investigator for various European research projects (CEMP, PROFES, HYPER, SOFTQAULI, KOBRA, CORONET). He has extensive experience in industry collaboration and technology transfer (Allianz, Bosch, City of Calgary, Corel, DaimlerChrysler, Ericsson, Nokia, Nortel, Schlumberger, Siemens, Stonesoft, Trema).

Professor Ruhe visited ISCAS in 2011 and we established a close collaboration relationship with each other.
