摘　　要：介绍了一种用于空中交通流量管理系统(traffic flow management system,TFMS)中流量仿真的虚拟管制员模型(virtual controller model,VCM)。流量管理主要关注空域流量变化趋势,以及当流量需求过大或者空域容量不足时,流量管制员如何采取流量控制措施平衡流量与容量。为了预测未来一段时间内扇区流量与容量是否平衡,并评估流量控制措施是否有效,提出了虚拟管制员模型。该模型根据扇区空域结构进行建模,使用扇区容量、流量控制措施对航班进行调配,计算调配后的流量与容量匹配程度。将虚拟管制员模型用于流量管理系统中,并使用一天的真实历史数据进行验证,对使用流量仿真模型预测的扇区流量和真实的数据进行对比实验,验证了虚拟管制员模型的预测能力。该方法适用于空中交通流量管理系统。This paper develops a new paradigm for building virtual controller model （VCM） for traffic flow simulator, which is applied to traffic flow management system （TFMS）. The problem of interest is focused on the flow tendency of airspace and how flow control measures are applied by air traffic controllers when demand is overage or capacity shortfalls in the airspace. The paper presents the virtual controller model in order to estimate the balance between the traffic flow and the capacity of sector in future, and assess the effect of flow control measures. The VCM is modeled on the sector airspace system, uses sector capacity and flow control measures to adjust flights, and calculates the matching degree between flow and capacity. Numerical results are presented and illustrated by applying them to air traffic data for a typical day in the traffic flow management system. The results show that the predictive capabilities of the model are successfully validated by showing a comparison between real flow data and simulated sector flow, making this method appropriate for traffic flow management system.
