一种基于模糊判定的融合系统有效性评估方法

Evaluation for Information Fusion System Based on Fuzzy Theory

为满足对多传感器信息融合系统评估的需要,在综合分析融合系统的基础上,提出了包含性能度量、效能度量、作战效能度量的系统有效性指标集.结合模糊数学理论,利用均衡平均型算子建立了多层融合系统有效性评估体系,提出较完整的评估方法,并将该方法应用于实际的融合系统中,实现了对融合系统运行有效性的较为全面的评估,为融合系统的设计、融合策略的选择提供了新的依据.实践表明,该方法数学表达清晰明确,便于工程实现,是信息融合系统有效性评估的一种有效方法.

For the evaluation of multi-sensor information fusion system, a index was set up as the system validity, which included the measures of performance（MOPS）, measures of effectiveness（MOES）, and measures of force effectiveness（MOFES）. Using this index,a multi-level evaluation model was proposed by applying fuzzy synthesis evaluation, which was founded on the balanced averaging operators. This method cohtrihutes to fusion system design and fusion strategy selection. Also it is proved to be clear for mathematical description, and easy for engineering realization. In conclusion, this method is an effective way to evaluate information fusion system.
