Overview of SMART MMIS
Control Room • ADVANCED Control Room • Seated-type Compact Workstation • Elastic Tiled Alarm Display Method • Alarm Reduction Method • EID-based Information Display
• Human Factors Engineered Features • Enhanced Communications between Operators
• Enhanced Motor Tasks • Improved Detection Possibility of an Unanticipated Event in Early Phase of the Event Propagation
• Improved Situation Awareness even under Massive Alarm Status
• Enhanced Accessibility of Plant Information
Alarm and Indication System •
PARM(Proactive Alarm Reduction Method) is based on the contents of the past operating affects during the next time of the alarm reduction.
