摘　　要：在可拓学理论的物元模型基础上建立了适用于舰载直升机可靠性评估的物元模型,待评舰载直升机的关联函数通过可拓集合理论的关联函数计算得出,引入层次分析法确定物元模型中各评估指标的权系数,从而得出待评舰载直升机可靠性的关联度并对待评舰载直升机的可靠性所属等级进行评估。结合某舰载直升机实例进一步说明了层次分析法用于确定待评模型中指标权系数是可行的,同时表明该可靠性评估结果能够科学合理地反映待评直升机的可靠性等级。A matter-element model based on the matter-element of extencis theory was built for the reliability assessment of carrier helicopter.The relevance function of the evaluated carrier helicopter was calculated through the relevance function of extendible set theory.The weights of indexes in the matter-element model were defined by introducing the analytic hierarchy process,therefore,the reliability grade of the carrier helicopter and relevance degree can be obtained.The carrier helicopters were used as examples to further illustrate that it is possible to use analytic hierarchy process to define the weights of indexes,at the same time,it is proved that the results are scientific and reasonable.
