Robustness in Interaction Systems

We treat the effect of absence/failure of ports or components on properties of component-based systems. We do so in the framework of interaction systems, a formalism for component-based systems that strictly separates the issues of local behavior and interaction, for which ideas to establish properties of systems where developed. We propose to adapt these ideas to analyze how the properties behave under absence or failure of certain components or merely some ports of components. We demonstrate our approach for the properties local and global deadlock-freedom as well as liveness and local progress
