飞行疲劳风险综合评价量化研究

飞行员疲劳会降低对情境意识的觉知,导致判断能力和操作能力下降,威胁飞行安全。对飞行员的疲劳状况进行综合量化评价可以为控制和缓解飞行疲劳风险提供有效依据。通过综合分析飞行疲劳影响因素,在确立飞行疲劳风险综合评价指标体系的基础上,采用证据理论解决评价过程中遇到的不确定性问题,结合MATLAB软件进行算例仿真验证,实现对飞行疲劳风险的量化。结果表明:证据理论方法可以有效利用影响疲劳的各种评价指标综合判断飞行员的疲劳状况,实现评价结果量化。结合MATLAB软件计算可以作为飞行员自我评价的有效工具,也可以作为管理人员进行疲劳风险管理的工具。

Quantification Research on Flight Fatigue Risk Comprehensive Evaluation

Pilot fatigue may lead to the reduction of situation awareness and the ability of judgment and control,even the threatening of flight safety.The quantified evaluation of pilot fatigue risk could provide an effective basis for controlling and alleviating the risk.According to the comprehensive analysis of the flight fatigue influential factors,and based on the flight fatigue evaluating index system,the D-S evidence theory is used to solve the uncertainty problem in evaluation process,and a simulation verific...
