Abstract

For the advanced main control rooms (MCRs), various types of decision support systems have been developed. It is very important to design highly reliable decision support systems in order to adapt them in actual MCRs. In addition, to evaluate those support systems and validate their efficiency and reliability is as important as to design highly reliable decision support systems, because inappropriate decision support systems or automation systems can cause adverse effects. In this work, decision support systems are evaluated experimentally. The target system of this work is the integrated decision support system including an alarm system, a fault diagnosis system, a computerized procedure system, and an operation validation system. The result of the experiment showed that decision support functions reduce subjects' workload and failure probabilities.
