为提高民航安检人员的安检绩效，探究不同因素下安检人员危险感知能力与安检绩效的关系。基于模糊信号检测论，以辨别力和判断标准作为衡量安检人员危险感知能力的指标，采用2（经验：新手、老手）×2（时间压力：无时间限制、有时间限制）×2（违禁品出现概率：高、低）混合实验设计，分析经验、时间压力、违禁品概率对安检人员危险感知能力的影响。结果表明：经验和时间限制对安检绩效有显著影响，而违禁品出现的概率对安检绩效的影响不显著；经验对安检人员的模糊辨别力和模糊判断标准均有显著影响，老手组危险感知能力的总体水平大于新手组；时间限制会降低安检人员的模糊辨别力和低违禁品概率下的模糊判断标准，但会提高高违禁品概率下的模糊判断标准。重视安检技能培训、设定合理搜索时间与传送带速度可有效提高安检人员的危险感知能力，保障航空安全。

In order to improve the security performance of civil aviation security personnel, the relationship between security personnel's hazard perception ability and security performance under different factors was explored. Based on the fuzzy signal detection theory(FSDT), the discriminability and judgment criterion were used as indicators to measure the hazard perception ability of security personnel. A mixed experimental design of 2 (experience: novice, veteran) × 2 (time pressure: no time limit, time limit) × 2 (probability of occurrence of contraband: high, low) was employed to examine the impact of experience, time pressure, and probability of contraband on the hazard perception ability of security personnel. The results indicate that experience and time pressure significantly impact security performance, while the main effect of contraband probability on security performance is not significant. Experience has a notable effect on fuzzy discriminability and fuzzy judgment criterion, with veterans demonstrating higher overall hazard perception ability than novices. Additionally, a time limit reduces the discriminating power of security personnel under low contraband probability but improves fuzzy judgment criterion standards under high contraband probability. Attaching importance to security skills training, setting reasonable search time and conveyor speed can effectively improve security personnel's hazard perception ability and ensure aviation safety.
