Avoiding the Camouflage Effect: Questionable Practices That Are NOT High Performance HMI!(PPT)

摘要

1. High performance concepts were significantly better in assisting the operator in: 1.1. Achieving and maintaining situation awareness, 1.2. Recognizing abnormal situations, 1.3. Recognizing equipment malfunctions, 1.4. Dealing with abnormal situations, 1.5. Embedding knowledge into the control system, 2. Operators highly rated the overview screen - 'big picture' situation awareness, 3. Even with only 3 hours total with the new graphics, operators had no difficulties in operating the unit. The High Performance graphics have intuitive depictions. 4. Very positive operator comments on analog depictions, alarm depictions, and embedded trends. 5. Consistent positive comments on how 'obvious' the HPHMI made the process situations. 6. Values moving towards a unit trip were clearly shown and noticed. 7. HPHMI would enable faster and more effective training of new operations personnel.
