基于SOA的民航航班延误波及分析与预警系统

Flight Delay Propagation Analyzing and Predicting System of Civil Aviation of China Based on SOA

为了对航班延误预警提供软件支撑,基于SOA思想设计并实现了航班延误波及分析与预警系统。服务端采用Web服务封装核心延误波及分析和预警算法,以图形组件包自动生成航班延误波及DAG、高级Petri网、贝叶斯网络和元胞自动机等数学模型的仿真视图以及棒图等统计图。客户端采用自主设计的Magix AJAX框架实现。模块之间以XML作为数据交换媒介,提高了互操作性。系统支持对单航班计划、多航班计划、机场、航空公司等的延误波及分析和预警功能。仿真实验表明,该系统可以有效地辅助完成航班延误波及分析和预警。

To provide software foundation for predicting flight delay,a flight delay propagation analyzing and predicting system was designed and implemented based on SOA. In server side, algorithm of flight delay propagation analyzing and predicting was encapsulated in a Web service, and a graphic component package was offered to automatically generate simulation graphs of flight delay propagation DAG, advanced Petri net, Bayesian network, parallel cellular automata, and statistical graphs such as a bar graph. The client side was implemented by Magix AJAX framework. XML is used as da- ta exchange media among modules to gain good interoperability. The system can be used to accomplish flight delay propagation analyzing and predicting for single flight plan,multiple flight plans, airports and airlines. It shows that the system can effectively aid flight delay propagation analyzing and predicting.
