Abstract : We are interested into diagnosing discrete-event systems modeled by an automaton. To allow uncertain observations, we represent them by an automaton. The diagnosis is then defined as the synchronization of the two automata. To enable an incremental and on-line computation of the diagnosis, we define a structure called automata chain, which represents the observations by periods called windows. It is possible to make a diagnosis for each period, and to refine the
result by checking that the final state of a window is the initial state of the next window. Since the global model is to big to be computed, we have adapted our results to enable the decentralized diagnosis. Finally, we extended our results to reconfigurable systems, i.e. so that the components and connections between the components can be added, modified or removed.
