An automata based method for online synthesis of emergency response procedures in batch processes

Rapid response to remove (or reduce) the detrimental effects of accidents has always been an important safety issue for the chemical industries. A systematic strategy is presented in this paper to synthesize emergency response procedures in any given batch system. Specifically, two distinct sets of automata are first constructed offline to model the plant behaviors and the control specifications, respectively. On the basis of these automata, an admissible supervisor can be synthesized online for a diagnosed failureinduced system state by applying the parallel composition operation. For the purpose of identifying an
