Diagnosis of Active Systems

This book is about model-based diagnosis of a class of discrete-event systems called active systems. Roughly, model-based diagnosis is the task of finding out the faulty components of a physical system based on the observed behavior and the system model. An active system is the abstraction of a physical artefact that is modeled as a network of com­ municating automata. For example, the protection apparatus of a power transmission network can be conveniently modeled as an active system, where bre
