天气影响的机场容量概率分布研究

天气是影响机场容量下降的主要因素,为了反映预测天气对容量的影响,建立了n-阶段到达容量分布模型。通过天气类型决策树将历史天气数据转换为每种天气类型的到达容量概率分布。根据天气类型的容量概率分布,用全概公式将概率天气预测转换为概率容量预测。基于5年的机场小时天气数据,对某一日的预测天气进行算例仿真,得到了一组基于预测天气的n-阶段容量概率分布。结果表明,n-阶段容量分布模型能够将机场不同时段的预测恶劣天气转换为预测随机容量,从而满足实时流量管理的需要。

Probability Distribution of Airport Capacity Affected by Weather

Weather is a major factor causing airport capacity reduction.To reflect the impact of the weather on capacity,the n-phase arrival capacity distribution model is established.The historical weather data are translated into the capacity probability distribution for each weather type through weather type decision tree.According to the capacity probability distribution of each weather type,the probabilistic weather forecasts are translated into probabilistic capacity forecasts by using total probability formula....
