The Changing Rule and Intervention Strategy of Long-voyage Crew's Alertness

Abstract: In order to reveal the change law of long-voyage crew alertness in the time dimension of voyage, determine the best time for long-voyage crew alertness intervention, and design the intervention strategy to improve long-voyage crew alertness, this study designed and carried out a series of long-voyage simulation experiments based on the needs of long-term voyages. The results of the study found that the rhythm of the simulated crew is disturbed and the best and worst changes are reversed on the prometaphase of the mid-long-term voyage, which may mean rhythm disturbance is one of the reasons for the alertness sharp declining of the crew. The ERPs latency of target locking the alertness test has no significantly different in the before, middle and after stages on mid-short voyage, that is, the time of detecting target is no delay, but the response time increases, indicating that the decrease of alertness of the crew on mid-short voyages may be related to the decrease of response ability. Based on the above results, the intervention timing for alertness was determined, intervention strategies were designed, and the effectiveness of intervention strategies was verified through experiments.
