Fuzzy AHP and its application in effectiveness evaluation for radar netting

摘要: 由于雷达系统组网效能评估和优选工作涉及多个指标和大量的模糊属性,导致了决策工作的困难.把拓展的模糊层次分析方法AHP(Analytic Hierarchy Process)引入雷达组网系统效能评估领域,提出了组网雷达作战效能评价指标层次,根据区间数判断矩阵的有关概念,得到了区间数判断矩阵排序权向量或综合评价值的计算方法,利用概率分布法对各最底层元素关于最高层准则的总组合权重进行排序.应用基于区间模糊数判断矩阵的模糊AHP法,建立了模糊评判模型.实例分析结果表明该方法具有实用性,其评估结果可以辅助指挥员提高雷达组网布防决策的准确性和科学性.Abstract: Difficulties in evaluating effectiveness and selecting an optimum scheme for radar netting arise as a result of the different goals involved and the large number of attributes considered. Our approach was based upon a fuzzy extension of the AHP (analytic hierarchy process), which was applied to the effectiveness evaluation for radar netting. The evaluation index hierarchy for radar netting’s effectiveness evaluation was presented, and some definitions of the interval judgment matrix were introduced. The methods of calculating weight-vector or comprehensive evaluation value of interval judgmentmatrix were summarized generally. Utilizing the probability distribution method, the ordering of chief combination weights was investigated for the lowest level according to the highest level. Fuzzy AHP was applied based on interval judgment matrix,and the fuzzy judgment model was set up for radar netting’s effectiveness evaluation. The practical example shows practicability of the method and the results can help commanders improve accurate and scientific decision in deploying radar netting.
