Automatic Fault Behavior Detection and Modeling by a State-Based Specification Method

Safety assessment methods are typically based on the reliability of the single components making a system. A different notion of safety as an emergent property of the system taken as a whole is however emerging. The current state-based modeling paradigm tends at misrepresenting systemic behavior, thus contrasting the adoption and development of systemic compositional fault detection techniques. We propose a state-based formalism, highly committed towards the explicit representation of systemic behavior, by which it is possible to formally identify faulty behaviors once the regular one has been specified.
