Abstract [en]

We present a model based approach to diagnosability analysis for interacting ¯nitestate systems where fault isolation is deferred until the system comes to a stand-still. Local abstractions of the system model are used to alleviate the state spaceexplosion. Pairs of closely coupled automata are merged and replaced by a sin-gle automaton with an equivalently behavior as seen from the rest of the system;interaction between the merged automata is internalized and the new equivalentautomaton is subsequently abstracted from internal behavior irrelevant to fault iso-lation. In moderately concurrent systems these steps can often be iterated until thesystem consists of a single automaton providing a compact encoding of all possiblefault scenarios of the original model. We illustrate how the resulting abstractioncan be used as a basis for post mortem diagnosability analysis.
