Abstract

Abstract:

To improve the evacuation efficiency and ensure the safety of passengers on an open deck in the event of an accident, a heterogeneous evacuation model considering passenger heterogeneity and group effect was constructed using AnyLogic software. Four simulated evacuation scenarios, including individuals, two-person, three-person and mixed groups, were constructed, and the evacuation process of heterogeneous passengers under different group sizes was simulated. The results indicate that with the increase of the group size, the total evacuation time increases nonlinearly. Specifically, the evacuation time for passengers in two-person, three-person and mixed-group scenarios is 11.8%, 19.6% and 15.5% longer than that in individual evacuations, respectively. Additionally, the peak of passengers' arrival at the terminal occurs in the early and middle stages of evacuation. In group evacuations, the higher expected passenger speed correlates with more dispersed arrival time distributions. These findings highlight the interaction effect between heterogeneous passengers and group effect in the evacuation process.

Key words: heterogeneity of passengers, group effect, cruise ship evacuation, evacuation simulation, open deck
