摘要
机场管制是航空运输过程中至关重要的一环,其安全性对航空运输的可持续发展至关重要.针对机场管制系统运行过程中可能出现的风险进行预测,依据SHEL模型,构建管制系统风险指标体系,从体系中选取影响较大的冲偏出跑道、跑道侵入、跑道外接地三类事件,在传统的灰色预测GM(1,1)模型的基础上,加入BP神经网络组建GM-BP灰色神经网络预测模型进行风险预测.预测结果显示,所采用的GM-BP预测模型预测的精度较高,同时得益于其对数据的综合处理能力和对复杂系统的有效建模能力,在机场管制系统运行风险预警方面有着广泛的适用场景,为后续针对可能出现的风险实施风险管理提供了科学的参考.
Abstract
Airport control is a crucial part of the air transportation process,and its safety is vital to the sustainable development of air transportation.This paper mainly focuses on predicting the risks that may occur during the operation of the airport control system,and the control system risk indicator sys-tem is constructed based on the SHEL model.Three types of events,namely,runway runout,runway in-cursion,and off-runway grounding,are selected from the system,and on the basis of the traditional gray prediction GM(1,1)model,BP neural network is added to form a GM-BP gray neural network prediction model for risk prediction.The prediction results show that the GM-BP prediction model used in this pa-per has high accuracy,and thanks to its comprehensive data processing capability and effective modeling capability for complex systems,it has a wide range of applicable scenarios in the operational risk warning of airport control system,which provides a scientific reference for the subsequent implementation of risk management for possible risks.
