A Semi-Quantitative Method of Safety Resilience Assessment for Airport Operation System based on FRAM Model

With the development of civil aviation, the airport system has gradually developed into a highly complex and intelligent soci-technology system. In order to enhance the ability of the airport system to resist emergencies, a safety resilience management framework model for airport operation system based on resilience theory is proposed, which includes pre-during-post stage of accident/incident events. Additionally, this paper mainly constructs a method of the safety resilience loss assessment for airport operation system based on FRAM model with unsafety event of the corridor bridge as a study. The method is used to assess the level of the safety resilience loss of the airport operation system and through the coupling analysis between the elements of the FRAM model the FRAM damping model is obtained. This assessment of airport safety resilience loss verifies the feasibility of this model and provides a new method for solving the multi-factor coupling influence problem of current airport safety research. This method helps managers evaluate the emergency response capabilities of each subsystem in the airport system and contributes to the promotion of safety resilience of airport systems.
