Abstract:  This paper uses the Pathfinder simulation software to study the human resource allocation of nursing staff in the elderly care facilities from the perspective of safe evacuation, in order to provide a theoretical basis for the human resource allocation of auxiliary evacuation personnel in the safe evacuation of single and multi-storey elderly care facilities, and provide a basis for the formulation of relevant policies and measures. The results show that: At the manpower supply stage, with the increase of the number of nursing staff, the evacuation time decreases, but the marginal utility decreases. At the stage of external manpower re supply, the fire with the increase of fire fighters, evacuation time decreases, the marginal utility decreases. There is aptimal point for both of the stage, with the most obvious aptimal point for both of the stage, with the most obvious decrease of time, after that the improvement is samll, or even reduce the efficiency.
