基于Choquet模糊积分的目标威胁评估方法

Target Threat Assessment Based on Choquet Fuzzy Integral

针对因素相关的威胁估计问题,提出了基于Choquet模糊积分的威胁估计方法。该方法通过gλ模糊测度对威胁因素和因素集的重要程度进行建模,利用因素的Shapley值,根据Marichal熵求解gλ模糊测度,并通过Choquet模糊积分实现目标威胁程度的估计。最后,以空战目标威胁估计问题为例,验证了方法的有效性。

A technique for Threat Assessment （TA） based on choquet fuzzy integral is proposed to solve the problem of TA with interdependent factors. Factor/Factors importance is modeled by gλ fuzzy measures. The gλ fuzzy measures are obtained on Marichal entropy using factor＇ s Shapley values. And the values of threat assessment are calculated with Choquet fuzzy integral. The validity of this method is exemplified by air combat threat assessment.
