【摘要】：综合航空电子系统是战机的神经中枢,需要对系统的综合效能进行快速宏观评估’为武器装备研制方案的设计提供方向性指导。为了更合理的评估航电子系统效能’本文在分析指标间相互关系的基础上,提出丁一种基于ANf方法建立网络化评估指标体系的权值优化方法,以获得优化的指标权值排序。论文主要工作包括以下几个方面:(1)针对实际评估指标体系建立过程中各评估指标之间存在相互依赖,考虑指标间的相互影响,本文在论述评估指标相关性和多专家信息融合等关键技术的基础上’基于信念图融合专家信息确定指标关联度,构建综合航空电子系统效能网络化评估指标体系。(2)综合考虑各专家的知识水平,提出专家权重动态赋予法,融合专家判断信息’从而进一步的提尚评估结果的准确度。(3)在网络指标体系的基础上,提出了基于ANP的综合航电系统效能幂指数评估模型构建框架,构建ANP超矩阵及加权超矩阵,通过对加权超矩阵进行极限运算’获得优化的指标权值排序。采用权值优化的效能评估方法对战机的任务想定方案的单项效能进行评估’并与传统的AHP评估方法对比,结果表明优化后的效能评估法得到的指标权值更符合实际情况,综合航电系统效能评估结果的可靠性和可信性也得到了进一步地提高。
[Abstract]:The integrated avionics system is the nerve center of the fighter plane. In order to evaluate the effectiveness of avionics system more reasonably, this paper is based on the analysis of the relationship between indexes. Go. In this paper, a weight optimization method based on ANf is proposed to establish a networked evaluation index system. The main work of this paper includes the following aspects: 1) there is interdependence among the evaluation indexes in the process of establishing the actual evaluation index system. Considering the mutual influence of indicators, this paper discusses the key technologies of evaluation index correlation and multi-expert information fusion, based on belief map fusion expert information to determine the index correlation degree. Constructing the evaluation index system of integrated avionics system effectiveness based on network. 2) considering the knowledge level of each expert synthetically, the method of expert weight dynamic endowing is put forward. On the basis of the network index system, a framework of power index evaluation model of integrated avionics system based on ANP is put forward. The ANP hypermatrix and the weighted hypermatrix are constructed. Through the limit operation of the weighted hypermatrix, the optimization index weight ranking is obtained. The effectiveness evaluation method of weight optimization is used to evaluate the individual effectiveness of the fighter's mission scenario scheme 'and to evaluate it with the traditional AHP evaluation method. Method contrast. The results show that the index weights obtained by the optimized effectiveness evaluation method are more in line with the actual situation, and the reliability and credibility of the effectiveness evaluation results of the integrated avionics system are further improved.
