Strategy Deduction for Improving Aviation Emergency Rescue Capability from the Perspective of Public Safety

Aviation emergency rescue plays a crucial role in the emergency management of various emergency events. Consequently, the processes of identifying relevant constraints of aviation emergency rescue ability, analyzing the interactive relationship among factors, and putting forward an economical and effective improvement strategy for aviation emergency rescue capabilities have become widely popular among scholars. To greatly improve the economic input efficiency of aviation emergency rescue capabilities, 18 relevant influencing factors were screened and identified from four perspectives: system institutionalization, technological advancement, rescuer professionalism, and operation safety. Then, the causal relationship among the influencing factors and the feedback mechanism were analyzed via the system dynamics (SD) method, and the influencing factor weights were calculated via the entropy weight method. Then, the equations of state variables and constants among the influencing factors were determined, and an SD model of aviation emergency rescue was built. Finally, a case study based on a practical construction condition of an aviation emergency rescue in Henan Province, China was analyzed. The variation trend of rescue ability was predicted from the temporal dimension, and the optimal economic input strategy for effectively improving the rescue ability was determined. Results demonstrate that the efficacy level of aviation emergency rescue ability in Henan Province is 44.97. The aviation rescue ability level on the 49th month can be improved to 90 if the monthly input into the aviation emergency rescue is raised to 3 million RMB. Additionally, the aviation rescue project can be significantly improved if the input proportions of operation safety, rescuer professionalism, system institutionalization, and technological advancement are 0.4, 0.2, 0.2, and 0.2, respectively. This work can provide an economic decision reference for building and perfecting public safety systems.
