摘要
根据系统效能模糊评价矩阵,在计算系统效能隶属度时要经过一系列的隶属度转换;但是,已有的隶属度转换算法都不能揭示"指标隶属度中哪部分对目标分类有用,哪部分无用";结果是指标隶属度中原本对目标分类不起作用的冗余数值也被用于计算目标隶属度。为此,从对目标分类角度设计一种滤波器,能识别指标隶属度中对目标分类不起作用的冗余数值,提取对目标分类起作用的有效值计算目标隶属度,由此建立实现隶属度转换的一般算法,并用于卫星导航系统效能评估。
According to the fuzzy evaluation matrices of the system effectiveness, calculate of the membership of system effectiveness have to pass though a series of transformation. However, existing membership transformation algorithms haven＇t revealed which parts of the membership of evaluations are useful for target classification and which useless. And the redundant values, which play no role in the process of classifying targets in the membership of evaluations. For this purpose, we can design a kind of filter distinguishing the redundant values in the membership of evaluations. By the filter, we can set up a general algorithm for realizing the membership transformation that be used for the evaluation of the system effectiveness.
