Maloperation consequence identification in process transition
Based on hazard and operability study (HAZOP) and concept of qualitative simulation, an automatic method for adverse consequence identification of potential maloperation is proposed. The method was shown by a heating furnace process. The results show that automatic control process can be simulated qualitatively; hazard and state evolution of qualitative model can be identified for given maloperation.
