Abstract:Considered the uncertainty of the risk assessment factors of airport apron operation, a risk assessment model for airport ramp operation based on game theory set analysis model was proposed. According to the process of apron control operation, a apron control operation risk evaluation indicator system was established, covering the four aspects of "man, machine, environment, and management." Based on the theory of game theory, the subjective weights obtained from the analytic hierarchy process method and the objective weights obtained from the entropy weight method are optimally combined to determine the weights of the indicators;the comprehensive connection degree of the samples is calculated by the similarity, difference and inverse model of the set pair analysis theory, and the apron operation risk level and development trend are determined, thus the reasonable safety recommendations are proposed. Finally, through the example verification, the evaluation results of the samples are basically consistent with the actual situation, which proves the reliability of the evaluation model.
