Overview

Simulation evaluates evacuation efficiency in Ro-Ro ships during stress, suggesting dynamics for improved safety.

Key Points

  • This research aims to evaluate the psycho-behavioral interactions that impact evacuation efficiency in Ro-Ro passenger ships under stress.
  • Developed a coupled simulation model integrating psychological stress and behavioral responses.
  • Utilized AnyLogic platform to analyze five evacuation scenarios.
  • Compared evacuation efficiency metrics related to psychological stress and exit choices.
  • Dynamic congestion avoidance improves evacuation efficiency by 7.58% compared to perceptual-decay herding.
  • Lifejacket retrieval efficiency increases by 14.31% with early preparation and stress management techniques.
  • Maintaining low stress levels helps reduce bottleneck effects during evacuations.
