Extracting Component-Oriented Behaviour for Self-Healing Enabling

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 in depth properties of the ESA ExoMars Rover. We show here how to enable GEAR’s gamebased 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. This way, we close the gap between the design-time and the run-time techniques provided in the SHADOWS platform for self-healing of concurrency, performance, and functional issues.
