Abstract: To accurately and objectively evaluate the security safeguarding ability of aviation security personnel, based on the theoretical analysis and the analysis of their work, 34 security safeguarding ability characteristic elements were proposed as secondary evaluation index, such as service consciousness, professional consciousness and security consciousness. Then three first-level indicators were put forward by exploratory factor analysis and the weight of each evaluation index was determined through AHP. Finally the security safeguarding ability evaluation model was established by the fuzzy comprehensive evaluation method and an empirical analysis on the model was made. The results show that the evaluation results of the proposed security safeguarding ability evaluation model are consistent with aviation security personnel's actual security safeguarding ability, and that the model proposed can effectively avoid the inconsistency between the current level of aviation security personnel and his or her actual ability.
