摘要:

为准确评估监视信息质量,给空中交通管制(ATC)提供决策依据,预防事故的发生,从目标航迹完整性、精确性、正确性等3个方面出发,构建由跟踪完整性、参数完整性、位置精度、速度精度、航向精度、参数正确性和目标真伪值等7个指标构成的监视信息质量评估体系;以总偏差最小为目的将可拓层次分析法 (EAHP)和熵权法有效结合确定指标权重,经加权求和得到监视信息质量评估值,通过对比专家划分的标准,判断各目标质量评估值对应的等级;以华北地区某扇区某时间段的9个目标为例进行试验仿真。结果表明:9个目标评估结果与专家分析相符,该评估指标体系可以实时评估监视信息质量,有利于提高空管监视系统安全水平。

Abstract:

In order to accurately evaluate monitoring information quality and provide decision-making reference for air traffic control (ATC) so as to prevent accidents, an information quality evaluation system was developed. Firstly, seven indices were chosen from three perspectives of integrity, accuracy and correctness, and they included target tracking integrity, target parameter integrity, position accuracy, velocity accuracy, heading accuracy, parameter correctness, probability value of true target. Secondly, with minimum total deviation as an aim, weights of these indices were determined by employing EAHP and entropy before evaluating value of monitoring information quality was obtained through weighted sum. Then, corresponding level of estimated values were decided through comparison with evaluating standards set by experts. Finally, simulated experiment was conducted with nine target trajectories in one period of a sector in North China as an instance. The results show that the evaluating results of the nine target trajectories are consistent with experts' analyses. The proposed evaluating system provides an effective and reliable approach to assess monitoring information, which can improve ACT safety.
