应急情形下的团队协调对于核电站主控室的安全和效率至关重要。信息技术的引入给主控室班组的协调过程带来了高度的复杂性和不确定性。然而，现有研究缺乏对应急情形下核电站主控室团队协调及其支持工具的研究。本论文针对核电站主控室团队协调行为分类系统、团队协调失效原因、团队协调行为模式和支持团队协调的界面设计方法开展了一系列研究。 本论文首先建立了应急情形下核电站主控室团队协调行为分类系统。通过综述医疗、航空和核电领域的协调行为分类系统，获得了基本的协调行为。通过对主控室操纵员的半结构化访谈和对主控室班组训练的观察，识别出文献中未发现的协调行为。并通过对另一组操纵员的问卷调查，验证了24种协调行为在核电站主控室中存在。最后，通过整合主控室班组的工作流程，建立了包含7个工作阶段、24种协调行为的团队协调行为分类系统，并且通过案例研究验证了分类系统的可靠性和可行性。 基于建立的协调行为分类系统，本论文对应急情形下团队协调失效原因和协调行为模式进行了深入研究。通过对主控室操纵员进行深入访谈并采用扎根理论进行质性分析，归纳出包含工作流程、个体特征和团队与环境三个层面的共24个协调失效原因。此外，对采集的模拟事故处理视频中协调行为进行分类系统编码，通过延迟序列分析的方法研究协调行为模式，并进一步比较了两种协调失效水平下团队协调模式的异同。结果表明，隐式协调行为、监视管理行为、相互交替的协调行为、确认动作和适当的干预与帮助有利于减少应急情形下主控室班组的协调失效，提高班组协调绩效。 根据上述结果，本论文从界面设计和团队训练的角度提出了改善协调状况的建议，进一步研究了核电站主控室中支持团队协调的界面设计方法。本论文设计了“约定备忘录”和“操作活动图”两种界面工具，开发了原型系统，通过实验方法研究了界面设计方法对团队协调和团队绩效的影响，验证了界面工具的有效性。结果表明，界面工具的使用有助于减少团队协调失效，提高协调满意度、班组情境意识和班组透明度，同时降低了操纵员的主观工作负荷，缩短了规程操作时间。 本论文的研究成果为核电站主控室的系统和流程设计、人机界面设计、运行管理、班组评价和培训提供了有价值的参考。

Team coordination during emergencies is critical to the safety and the efficiency of nuclear power plant main control rooms. Information technology brings high complexity and uncertainty to the team coordination in digital main control rooms. So far, studies on the team coordination and its support tools in nuclear power plant main control rooms during emergencies are very rare. This study conducted studies on the taxonomy of coordination behaviors in nuclear power plant main control rooms, the causes of coordination failure, the patterns of coordination behaviors, and the design of human-computer interface that supports team coordination. This study developed a taxonomy of coordination behaviors that specific to nuclear power plant main control rooms. This study obtained basic coordination behaviors through reviewing the existing taxonomies in the healthcare, aviation, and nuclear domain. Based on the semi-structured interview with field operators and the observation of the training of control crews, this study identified coordination behaviors that not included in the existing coordination taxonomies. The existence of twenty-four coordination behaviors was validated based on the interview with another group of operators. By integrating control crews’ workflow to the development of taxonomy, this study established a taxonomy of coordination behaviors which included seven workflow stages and twenty-four coordination behaviors. The reliability and validity of the taxonomy was confirmed by a case study. Based on the established coordination behavior taxonomy, this study investigated the causes of coordination failures and the patterns of coordination behaviors in emergency situations. Based on the indepth interview with control crew operators and the qualitative analysis with the Ground Theory, this study summarized twenty-four failure causes which were integrated into three aspects, namely work processes, individual characteristics, and situation and organization. In addition, this study coded the behavior data in the videos of handling simulated emergencies, conducted lag sequential analysis on these data, and compared the differences of behavior sequences between control crews with high coordination failure ratio and low coordination failure ratio. The results indicated that implicit coordination behaviors, supervisory behaviors, reciprocal behaviors, and suitable interventions and provided timely help contributes to the reduction of coordination failures and the enhancement of coordination performance of control crews in emergency situations. According to the results above, this study proposed suggestions to improve team coordination from the aspects of interface design and team traning, and then studied on the methods for designing human-computer interfaces in nuclear power plant main control rooms. This study designed two interface tools-coordination request memo and operation activity chart, and developed a simulated nuclear system to investigate the influence of interface design on team coordination and team performance. The experiment results confirmed the validity of the two interface tools. Specifically, the use of the interfaces tools helped participants reduce the number of coordination failures and improved the satisfaction of team coordination, the team situation awareness, and the team transparency. Meanwhile, the interface tools helped reduce the subjective workload and shortened the operation time. This study provides valuable information for the design of systems and workflows, the design of human-computer interfaces, the operation management, and the evaluation and the training of control crews in nuclear power plant main control rooms.
