近距平行跑道容量及延误水平计算模型

为了精确评估近距平行跑道容量及其延误,建立了符合实际运行特点的近距平行跑道运行时空图,借鉴经典单跑道混合运行模式下的容量和延误水平计算模型,对离港航班采取插缝放行,利用双排队系统理论与逻辑推理方法,分别建立了近距平行跑道容量与平均延误水平计算模型,并运用仿真方法对模型进行了验证,将模型计算结果和仿真结果进行了比较。对比结果表明:跑道容量差异率为0.58%,最大平均延误和队列差异率分别为1.7%和1.4%,因此,建立的模型客观反映了近距平行跑道系统实际运行状况,是可行的。

Calculation models of capacity and delay for closely spaced parallel runway

In order to accurately assess the capacity and delay of closely spaced parallel runway,a time-space diagram was established in accord with realistic operational features,the calculation models of the capacity and delay under the classic mixed operation mode of single runway were referred,departure flights were allowed in the intervals of arrival flights,double queue system theory and logical discursion method were utilized,the calculation models of the capacity and average delay for closely spaced parallel runway were built separately,simulation method was used to check the models,and the calculation result and the simulation result were compared.Comparison result shows that the differentia rate of runway capacity is 0.58%,the maximum differentia rates of the average delay and queue are 1.7% and 1.4% respectively,so the new models reflect the realistic operational situation of closely spaced parallel runway,and are feasible.
