Abstract:

In order to explore the impact of panic psychology on the evacuation process of civil aviation passenger aircraft
(abbreviated as civil aircraft) passengers, based on the consideration of environmental factors, self-regulation factors and population influencing factors, Anylogic software is used to establish the system dynamics model of propagation of panic psychology among passengers during cabin fires, and its parameter values are determined through
questionnaires and other methods. And the propagation and recovery of panic psychology among evacuees are simulated for different visibilities and temperatures in the cabin. The results show that, in the early stage of evacuation,
the smoke generated by the burning caused a decrease in visibility and an increase in temperature in the cabin,
leading to a rapid increase in the number of panicked people. Subsequently, under the influence of self-regulation,
crew guidance and positive information dissemination, the number of people in panic gradually decreased, and finally the number of people in panic and calm remains relatively stable and reaches a state of dynamic balance. The
study finds that the increase in passengers′ attention to cabin safety information can effectively reduce the time it
takes for the crowd′s emotions to reach a dynamic balance. This study has guiding significance for relieving passenger panic psychology and improving evacuation efficiency during emergency evacuation of civil aircraft.
