A Theory of Fault Recovery for Component-Based Models


This paper introduces a theory of fault recovery for component-based models. In our framework, a model is specified in terms of a set of atomic components that are incrementally composed and synchronized by a set of glue operators. We define what it means for such models to provide a recovery mechanism, so that the model converges to its normal behavior in the presence of faults. We identify \emph{corrector} (atomic or composite) components whose presence in a model is essential to guarantee recovery after the occurrence of faults. We also formalize component-based models that effectively \emph{separate} recovery from functional concerns.
