针对容量影响因素的不确定性,提出了基于证据理论的机场动态容量预测模型。该模型依据机场最大容量构建识别框架,以专家预测的各种不确定因素的影响程度和发生的可能性为证据,建立基本可信度分配,利用Dempster合成法则融合各种动态因素对机场容量的影响。实验数据分析表明,该模型运算结果合理,可以为空中交通流量管理提供科学的决策支持。
By considering the uncertainty of influence factors, a new dynamic capacity prediction model of airport's runway is proposed based on the Dempster--Shafer theory of evidence. According to the max capacity, this paper analyzes runway's capacity model, designs a recognized frame, takes the probabilities of the influence factors predicted by experts as the basic probability of evidences. At last, the Dempster fusion principles is used to get the probability of the runway's prediction dynamic capacity. Experimental results prove the rationality and feasibility of the proposed mode.
