【摘要】：航空信息支援系统在空中力量体系对抗过程中起着兵力倍增器的作用,对航空信息支援系统的能力进行定量评估具有重要的现实意义.在介绍了区间数和语言评估标度的基础上,分别提出了区间数的幂运算法则和语言评估标度转化为区间数的方法.通过将语言评价值转化为[0,1]上的区间数,从而实现了定性指标到定量指标的转换.将航空信息支援系统分解为系统能力矢量、人机交互矢量和人员行为矢量,进而分别建立了三个能力矢量的指标体系.应用区间数特征向量法确定了指标体系中各个指标的区间数权重,利用区间集结算子对三个指标体系中的各个指标进行聚合.提出了区间加权矢量和法,利用该方法对三个能力矢量进行聚合.最后通过实例说明了该方法的有效性.
[Abstract]:The aeronautical information support system acts as a force multiplier in the confrontation of the air power system. It is of great practical significance to quantitatively evaluate the capability of aeronautical information support system. Based on the introduction of interval number and linguistic evaluation scale, The power arithmetic of interval number and the method of transforming language evaluation scale into interval number are put forward, and the language evaluation value is transformed into interval number on [0]. Thus, the conversion of qualitative index to quantitative index is realized. The aeronautical information support system is decomposed into system capability vector, human-computer interaction vector and personnel behavior vector. Then, the index system of three capacity vectors is established, and the interval number weight of each index in the index system is determined by using the interval number eigenvector method. The interval aggregation operator is used to aggregate each index in the three index systems. The interval weighted vector sum method is proposed and the three capacity vectors are aggregated by this method. Finally, an example is given to illustrate the effectiveness of the method.
