Objectives  This paper researches on the evacuation of cabin crew which has a number of uncertainties. During evacuation, the behavior and attributes of personnel and the space state of the cabin should be considered.

  Methods  Through the functional division of the personnel model structure, the personnel evacuation model structure is determined, the personnel attributes are modelled, and the rules of personnel protection are established. Through dividing the cabin space model, plotting the cabin environment and grading the safety of subenvironments, the obstacles in the cabin are simulated and represented mathematically for the calculation via the 3D simulation software. Then by 3D evacuation simulation software, simulation tests for both single and multiple evacuation paths are carried out respectively. Besides, the selection of evacuation paths by the personnel in different working areas under specific condition are simulated so as to calculate the distance and time of evacuation.

  Results  The simulation results show that the evacuation model of the cabin crew can simulate the evacuation process accurately.

  Conclusions  The research findings provide basis for the auxiliary design of the cabin.
