| 摘 要： | 为了提高求解地面等待策略(ground holding policy,GHP)随机模型的效率,利用归纳法建立了延误损失公式;考虑空地费用比与典型容量样本概率的不同组合关系,采用枚举法对4类典型情况进行分析,得到了有效容量判别方法;将多个随机容量转化成单个有效容量,并利用有效容量求解随机GHP模型,结果表明:与传统方法相比,运用本文方法求解随机GHP模型得到的总延误损失相同,在2 h内起飞航班为50架次的条件下,计算时间由109 s减少到42 s,减少了61.5%,提高了计算效率.

| Abstract: | In order to improve the efficiency of solving the stochastic ground holding policy(GHP) model,the delay cost formula was established by induction method.Then,4 typical cases with different combinations between air-ground cost ratio and the probability of typical capacity scenarios were analyzed,and the discriminant method of effective capacity was derived by enumeration.After that,multiple stochastic capacities were transformed into one single effective capacity,and the stochastic model was solved using the... |
