“…Many studies tried to model operators' cognitive processes or information processing flows during the diagnosis process [5,[12][13][14][15][16][17][18][19][20][21][22][23][24][25]. While most of the studies focused on modeling cognitive processes in diagnosis tasks, some introduced strategies [5,13,24,25] that could be used in diagnosis tasks.…”

Recently, main control rooms have been considerably changed by modern computer techniques. Some of the features that distinguish digital control rooms from conventional, analog rooms in nuclear power plants include advanced alarm systems, graphic information display systems, computerized procedure systems, and soft control. These features can bring changes in operator tasks, changing the characteristics of tasks or creating new tasks for operators. It is especially expected that these features may bring out changes in the operator's diagnostic tasks and strategies in a digital control room as compared with an analog control room. This study investigates the differences in the operator's diagnostic tasks and strategies in analog and digital control rooms. This study also attempts to evaluate how new systems in a digital control room affect diagnostic strategies. Three different approaches, which are complementary, are used to identify diagnostic strategies in the digital control room and in the analog control room: (1) observation in the simulator, (2) interview with operators, and (3) a literature review. The results show that the digital control room introduces new diagnosis strategies compared with the analog control room while also changing the characteristics of the strategies, mostly by gaining more support from the computerized system.

“…5) According to the results of several published support system evaluations, a support system does not guarantee an increase in operator performance. 6) Some support systems could degrade an operator's situational awareness capability and may increase an operator's mental workload. It is very important to design highly reliable decision support systems for use in NPPs.…”

“…For a modernized interface consisting of LDP and LCDs, the number of navigated windows and time spent for a diagnosis could be used as the criteria for evaluating operator performance. 6) In this study, we experimentally investigated the effect of a decision support system on operator performance. Several decision support systems were selected as target systems for experiments.…”

As human error is recognized as one of the main causes of nuclear power plant (NPP) accidents, there have been efforts to reduce and prevent human error by developing various decision support systems. Before adapting these support systems to actual NPPs, it is necessary to validate their reliability and to evaluate their effect on operator performance. Particularly for safety-critical systems such as NPPs, the validation and evaluation of decision support systems is as important as the design of good systems. Such evaluations may be carried out through a theoretical modeling or experimentation. The objective of this study is to experimentally investigate the effects of decision support systems on operator performance. Several trends were observed in the results of the experiments in this study; the support systems reduced both human error and workload, and the impact of the systems was most readily observed during complex and highly workloaded situations in which an operator must handle a high volume of information.
