“…Simulations were usually used to study mode and mechanisms of team errors (Zou et al, 2017a), such as categorizing personnel errors or errors in cooperation (Sasou & Reason, 1999), assessing team behaviors (Sasou et al, 1993) and nding factors which increase the chance of errors. (Molesworth & Estival, 2015) (Saetrevik, 2015) Physiological parameters when team working, such as skin conductance response data, eye tracking data, etc., are measured and analyzed to assess team performance.…”

For complex metro systems to operate efficiently, effective cooperation among teams is needed. Many accidents happen due to control failure caused by team errors during cooperation. Improving the efficiency of teamwork not only focuses on the team’s organizational structure and teamwork procedure, but also stresses each workers’ state during cooperation, because personal errors or interactions errors may lead to the collaboration failure. Combining the theory of human error and the complex network theory, this paper proposes a method to identify team errors and explore the mechanisms of team error during teamwork in the metro systems. Team cooperation is decomposed into each team member’s information process and interactions among human, machines and the environment, which are connected by a collection of information flows in the task. The TICN (Teamwork Information Complex Network) is established, in which information state of individual and interactions within agents are represented by nodes, and information flows are represented by directed edges. Then, vulnerable information states causing teamwork failure are identified by analyzing the degree centrality and betweenness centrality of the complex network. In the end, the model is applied to a specific emergency. The result shows that team members need enhanced skill-based level cognitive ability, the station supervisor needs a thorough understanding of the management system and rules, the decision-maker has to make and communicate decisions concisely, and the communication equipment should be adjusted and designed according to ergonomic requirements. Based on the results, some suggestions were put forward to improve the team performance in the metro system.

“…Operators' behaviours and communications were recorded on VCR and audio tapes and later they were analysed based on team activity description method: TADEM (Sasou et al, 1993). An example of the communication flow in event 3 is shown in Figure 2, which includes both communications and annunciator indications observed in the simulator experiments.…”

“…As mentioned by Ujita et al (Ujita, Ikeda, Kubota, & Kawano, 1992;Ujita, Kawano, & Yoshimura, 1995), the performance of MCR operators in emergency situations in NPPs is strongly affected by not only the cognitive process for each operator, but also by communications and collaboration among operators. Sasou, Nagasaka, and Yukimachi (1993) indicated that the variables ''decision making '' and ''communication'' were the main factors to characterize team's behavior. Reinartz and Reinartz (1992) mentioned that verbal communications among MCR operators is not only the mechanism by which teamwork functions, but also an important clue in understanding the intermediate cognitive processes of MCR operators.…”
