摘　　要：通过理论分析和专家调查,总结了影响飞行疲劳的多方面因素,从工作因素和个体因素两个方面考察,进一步细分为执勤因素、飞行因素、环境因素、生理因素和心理因素,以这5个因素为准则,构建飞行疲劳风险评价指标体系。应用基于G1法的模糊综合评判法对疲劳状况进行评判,确定了指标体系中各指标的权重,建立了飞行疲劳风险多级模糊综合评价模型,并对模型进行了实例验证。结果表明,该方法可以给出机组人员飞行疲劳发生可能性的模糊评判结果。The present paper aims to introduce our study on the fuzzy comprehensive evaluation of the flight fatigue risk based on G1 method.As we know,for the time being,flight time limit is the main way to manage crew fatigue,however,it doesn＇t take into account the sleep and circadian rhythm,both of which have significant effects on the pilot＇s flight fatigue.Thus,when integrating the scheduling system into the fatigue accounting system,we have found that there exists a lack of scientific basis and pertinence.In order to manage the pilot fatigue risks in a more scientific way and guarantee the flight safety,it is necessary to adopt the theoretical analysis method and the expert investigation method by adding up the sleep hours in a day.Bearing the said point in our mind,we have summed up all the influential factors leading to the fatigue and introduced the two main aspects into our evaluation system,that is,the working（duty） factor and the individual factor.By a further subdivision on the two aspects,we have obtained another five first-level factors,all of which make up the flight fatigue assessment index system.More accurately speaking,the working（duty） factor involves duty factor,flight factor and the environmental factor.By the individual factor we mean the physiologic and psychological factors.Moreover,the above said five first-level factors can also form a set of subdivisions.For example,duty factor and flight factor both consist of four sub-level factors,whereas the environmental factor is made of three sub-level indicators and the physiologic factor and psychological factor include five subsequent elements,respectively.By using G1 method,we can also gain the evaluation weights of all the indexes.Besides,we have also classified the likely-to-be-taking place flight fatigue into the corresponding five grades in accordance with our study purpose.To make the evaluation method more valuable,we have invited ten experts in the line to test the membership grades of the second-level indicators.And,finally,we hav
