摘　　要：为缓解当前飞行流量需求与空域资源限制间的矛盾,改善静态流量分配方式下航路飞行流量限制问题,提出飞行流量动态调配概念并建立动态调配模型及算法。首先根据Volterra捕食模型的思想,以航路负荷值大小为依据划分种群,依据航路飞行流量的调配速度建立飞行流量的动态调配模型,然后提出实时流量动态调配算法,按时段周期性对航路的飞行流量重新划分种群,并根据航路当前状况对飞行流量进行动态调配。最后运用Matlab软件进行算例分析,结果表明了模型及算法的有效性,可以很好地应用于飞行流量的动态调配研究中。To ease the current contradiction between flight flow demand and airspace resource limitations and improve the problem of air route limiting flight flow,the author puts forward the concept of flight flow dynamic adjusting and establishes the flight flow dynamic adjusting model and algorithm.First divide the population types based on the route load value according to the ideas of the Volterra predation model and establish the flight flow dynamic adjusting model according to the speed of adjusting.Then put forward the real-time flight flow dynamic adjusting algorithm of redrewing the populations and dynamic adjust the flight flow according to the current situation of the route periodically.The author also analyses the numerical example by using the software of Matlab and the result shows the flight flow dynamic adjusting model and algorithm is an effective method to apply into flight flow dynamic adjusting.
