Abstract: Commercial safety analysis is one of the important components of system operation process analysis. However, the operation safety analysis of most existing models does not consider people, aircraft, operating environment and other influencing factors. Comprehensively considering the effects of system safety analysis functions such as time, control, resources, and premise, this article conducts a more detailed analysis of the factors affecting the safe operation of the system, and establishes a comprehensive and standardized quantitative safety analysis model. Using Rules describing Function Variability (RFV) and Analytical Hierarchy Process (AHP), we improve the Functional Resonance Analysis Method (FRAM), setting up a comprehensive commercial system safety analysis model. We employ the model to restore the required conditions for the safe operation of Flight 143, obtaining the conclusion that the coupling variation and functional failure should be mainly prevented. Additionally, the conclusions of the original accident investigation report are extended, demonstrating the feasibility of the model. The proposed theoretical model can provide theoretical reference and technical support for the safety of the operating system of airlines.
