基于聚类神经网络的机场拥挤等级预测

摘要

对机场拥挤机理进行分析；从后果类指标入手，提出基于饱和度的拥挤等级评价方法，建立机场拥挤5色预警等级，从原因类指标入手，提取出分别刻画机场容量和需求的5个拥挤特征指标；提出了基于聚类的神经网络分类算法；利用ATL机场实际航班数据进行实例验证，拥挤等级预测的准确度达到80%，预测效果优于BP神经网络。结果表明，提出的方法预测效果较好，具有一定的实用性。%The mechanism of airport congestion is analyzed. Evaluation method of congestion level is established based on satu-ration from result indicators. So the five-color warning level of airport congestion is established. 5 features are extracted for depict-ing airport demand and airport capacity from reason indicators. Neural network classifier algorithm based on cluster is proposed. Real flight data of ATL airport is used to verify this method. The accuracy is up to 80%. The results are proved to be super to the method of BP neural network. Thus the proposed method leads to better forecasting, is applicable for the real condition.
