The Role of Models in Self-adaptive and Self-healing Systems

Authors: Jens Happe, Heiko Koziolek, Umesh Bellur, Holger Giese, Wilhelm Hasselbring, Robert Laddaga, Margaria Tiziana, Josu Martinez, Christian Müller-Schloer, and Roland Reichle

Published in: Dagstuhl Seminar Proceedings, Volume 9201, Self-Healing and Self-Adaptive Systems (2009)

Abstract
Self-healing and self-adaptive systems dynamically react on changes in the environment. They enable software systems to adjust to new conditions and work optimally even in unstable environments. However, such systems have to cope with an ever increasing complexity and size of software systems. In order to handle such systems, models are an efficient means for analysis, control, and documentation. Furthermore, hierarchically structured models can make self-healing and self-adaptation manageable. In this report, we discuss several questions that address the role of models in self-healing and self-adaptive systems. We outline today's challenges and present different viewpoints on the application and benefit of models.

Component-Oriented Behavior Extraction for Autonomic System Design

Authors: Tiziana Margaria, Marco Bakera, and Christian Wagner

Published in: Dagstuhl Seminar Proceedings, Volume 9201, Self-Healing and Self-Adaptive Systems (2009)

Abstract
Rich and multifaceted domain specific specification languages like the Autonomic System Specification Language (ASSL) help to design reliable systems with self-healing capabilities. The GEAR game-based Model Checker has been used successfully to investigate properties of the ESA Exo- Mars Rover in depth. We show here how to enable GEAR’s game-based verification techniques for ASSL via systematic model extraction from a behavioral subset of the language, and illustrate it on a description of the Voyager II space mission.

Service-Oriented Design: The jABC Approach

Authors: Tiziana Margaria, Bernhard Steffen, and Manfred Reitenspieß

Published in: Dagstuhl Seminar Proceedings, Volume 5462, Service Oriented Computing (SOC) (2006)

Abstract
Reviewing our 10 years of experience in service engineering for telecommunication systems from the point of view of Service-Oriented Design then and now, we observe that much is common to the two communities. We aim in our current research at establishing a link to the notions used by the service-oriented programming (SO) community. We are convinced that combined approaches, that blend the flexibility of the current SO-scenario with the rigour and semantic standardization culture of the telecommunication community will dramatically increase the productivity of the development of a large class of software systems. Incremental formalization and automatic verification techniques may be again the key to achieving confidence and reliability for services that interact and interoperate on a large distributed scale.
