Abstract: A weighting method combining subjective and objective weighting,the former being G1 method and the latter being mean-square error method,was proposed to determine weights of indices of airport apron safety.A grey evaluation model for airport apron safety was presented using grey analysis and analytic hierarchy process.In the model,there is a two-level evaluation index system,with the first level indices being the safety of apron facilities,airport public security,management of apron operation personnel,management of vehicles in the apron,field management and coordinating ability,and other safety factors.An example shows that the proposed method can take full use of available information about the evaluation indices to evaluate the airport apron safety.
