摘要

在社会技术系统中,由多名团队成员组成的操作团队在应对非正常情况时仍然发挥着至关重要的作用。因此,考虑到可能影响团队成员绩效的各种绩效影响因素,人们提出了各种人类可靠性分析方法。遗憾的是,由于多种影响绩效的因素在不同的操作团队中可能存在差异(即机组间的可变性),因此如何系统地将这种可变性可视化至关重要。在这方面,将运营团队的文化特征与其绩效进行比较将是一个很好的起点。本研究基于从韩国国内核电站主控室操作团队收集到的经验数据,探讨了文化特征如何与不安全行为的发生相关联。使用霍夫斯泰德的五个文化指数对操作团队的文化特征进行了可视化,并将其与模拟非正常条件下观察到的不安全行为数量进行了比较。结果发现,不安全行为的发生与其中一个霍夫斯泰德指数之间存在统计学意义上的显著相关性。根据这一发现,预计在今后的工作中可以合理地确定一个相关的探究方法,以仔细研究机组人员之间的差异性。

Identifying a probe to visualize the variability of operating teams for supporting the human reliability analysis of nuclear power plants: An explanatory study
Operating teams consisting of several team members still play a critical role in coping with off-normal conditions in socio-technical systems. Thus, various kinds of human reliability analysis methods have been suggested based on the consideration of diverse performance shaping factors that can affect the performance of team members. Unfortunately, since multiple performance shaping factors can vary across operating teams (i.e., crew-to-crew variability), it is crucial to figure out how to visualize this variability in a systematic way. In this regard, comparing the cultural characteristics of operating teams with their performance would be a good starting point. This study investigates how cultural characteristics can be correlated with the occurrence of unsafe acts based on empirical data collected from operating teams working in the main control room of Korean domestic nuclear power plants. The cultural characteristics of the operating teams were visualized using five Hofstede's cultural indices and compared with the number of unsafe acts observed from simulated off-normal conditions. As a result, a statistically significant correlation is found between the occurrence of unsafe acts and one of the Hofstede's indices. From this finding, it is expected that a relevant probe to scrutinize crew-to-crew variability could be soundly determined in future works.
