基于粗糙集理论的防空C^3I系统目标威胁度综合评判

Grade of Thread Estimate Judgment in Aerial Defence C^3I based on Rough Set

目标威胁度的估计是防空C3I系统中辅助决策的基础,各个威胁因素权系数的确定历来缺乏严格的数学基础。针对此问题,提出应用粗糙集理论,对空防对抗中各种威胁因素的原始数据进行挖掘,利用其求得各项威胁因素的属性的重要度,进行权值化处理,使得各项威胁因素权系数的确定有效克服了传统方法的主观性,使得各项权系数的确定更具客观性,提高威胁度估计的准确性。

Grade of thread estimate is the basic of assistant decision in the aerial defence C3I system.but no mathematic basis is provided.Therefore,a method base on Rough Set theory is advanced int this paper to determine significance of each parameter and shift significance of attribution to weighting coefficient. Thereby,the method base on Rough Set theory overcomes the shortcomings of subjectivity of traditional methods in determining weights,possesses much more objectivity and improves the accuracy of estimation.
