摘要:

针对民机签派可靠性设计与评估方法问题,构建了基于多等级的签派可靠性模糊综合评价法。首先通过专家调查方式确定了民机签派可靠性的影响因素二级指标体系并按照重要程度进行分类。然后采用AHP法计算影响因素的权重,运用广义梯形模糊数确定隶属函数,并通过模糊中心法去模糊化,确定模糊关系矩阵,进而建立数学模型实现了对民机签派可靠性的模糊综合评价。最后结合某航空公司B737机队签派可靠性水平进行验证,结果表明该评价模型及其评估结果与实际情况基本一致。

Abstract:

For civil aircraft dispatch reliability design and assessment methods,the dispatch reliability model's construction is based on multi-level fuzzy comprehensive evaluation method. Initially through experts'research we determine the factors affecting civil aircraft dispatch reliability of the secondary index system and classify them according to their importance. Then using the AHP method we calculate the weight of the influencing factors,and their membership function by using generalized trapezoidal fuzzy number,and through the fuzzy interpolative method we can identify the fuzzy relationship matrix,then a mathematical
model can be established to achieve the fuzzy comprehensive evaluation of civil aircraft dispatch reliability.Finally when compared with airlines爷B737 fleet dispatch reliability level verification results,we can conclude that the evaluation model and its evaluation results are basically consistent with the actual situation.

Key words: civil aircraft dispatch reliability, fuzzy comprehensive evaluation, AHP, generalized trapezoidal fuzzy number, membership function
