Analysis of Ship Operator's Operation Ability and Research on Prevention of Human Error

Based on the theory of human error classification, combined with the characteristics of human error of ship control devices, through the analysis of memory, cognition and ability limits, the relevant ability restrictions of ship operators are correlated to analyze the impact of human error on ship control devices The factors are classified, mainly from the psychological state factors, the physiological state factors, the information in the memory, the individual's quality and ability factors to analyze the impact of people's work behavior. On the basis of influencing factors, the cognitive status of ship control devices under emergency conditions is analyzed according to actual conditions, and operational ability training indicators are proposed. The research results provide theoretical guidance for ship operators' operational ability training subjects and methods, and have practical significance for the prevention of ship operators' human errors.
