Identifying the individual factors is a major issue in determining the likelihood of human error and ultimately human reliability. In current human reliability assessment methods, this is determined based on a list of performance shaping factors and experts’ judgment. This was a qualitative content analysis study, in which the participants were selected using purposive sampling from combined cycle power plant control rooms. Semi-structured interviews were performed and collected data were analyzed. A total of 32 operators (20 module controllers, eight head operators and four managers) were interviewed. Five categories were extracted, namely ‘mental condition’, ‘consciousness at work’, ‘professional competence’, ‘communication skills’ and ‘quick reactions and decision-making capabilities’. Accordingly, it is suggested to taken into account such factors as professional competence and speed of reactions and to pay more attention to their important factors in the reliability of operators in combined cycle power plant control rooms.

识别个体因素是确定人为错误可能性和最终人为可靠性的主要问题。在当前的人类可靠性评估方法中，这是根据一系列性能塑造因素和专家的判断来确定的。这是一项定性内容分析研究，其中参与者是从联合循环发电厂控制室中使用有目的的抽样来选择的。进行半结构化访谈并对收集的数据进行分析。共采访了 32 名操作员（20 名模块控制器、8 名首席操作员和 4 名管理人员）。抽取出“精神状况”、“工作意识”、“专业能力”、“沟通能力”和“快速反应与决策能力”五个类别。因此，
