Dynamic Assessment Method for Group Decision-making Errors in Extreme Work Environment Driven by Team Cognitive Model

Abstract: Due to the task demands, team operating in extreme environments is socially isolated, subject to prolonged physical constraints, and exposed to significant risks. The cognitive functional structure of team was focused, and the submarine team was regarded as a social interaction unit. The cluster of Performance Shaping Factors (PSFs) was reconstructed, incorporating the Team-PSFs groups. In terms of member variability, the three-parameter Weibull distribution function was used to construct the human time performance distribution function. The quantitative models of different team cognitive failure modes were constructed that consider the communication information elements within the team, including individual independent transmission, communication shared transmission, and information transmission. The proposed methodology was validated through simulation in a typical task of manned submarine unpowered diving.
