摘要 应用复杂网络理论,从系统层面研究空域扇区网络的级联失效抗毁性,提出空域扇区网络级联失效抗毁性优化策略,以提升空域扇区网络级联失效抗毁性。首先,定义空域扇区网络节点负载和容量,分析空域扇区网络级联失效过程并建立模型,确立临界阈值和扇区非正常率为级联失效测度指标。然后,根据管制扇区运行特点,提出2种优化策略——基于扇区节点剩余容量的相邻负载再分配策略和局部负载再分配策略。通过仿真,分析了参数变化规律与网络抗毁性的关系,证明局部负载再分配策略可以大幅提升空域扇区网络级联失效抗毁性。 Applying the complex network theory,this paper studies the cascading failure invulnerability of airspace sector network at the system level,and proposes an optimization strategy to improve the failure resistance of airspace sector network cascade.First of all,the cascading failure model of sectors network is proposed,and the load and capacity of sectors network nodes are defined.The progress of cascading failure is analyzed,setting the critical threshold and sectors abnormal rate as the failure measurement indicators.Then,considering the operation characteristics of the control sector,two optimizing methods have been proposed:the adjacent load redistribution strategy based on the residual capacity of the nodes and the local load redistribution strategy.Based on the results of the simulation analysis,the local load redistribution strategy is proved to significantly boost the cascading failure invulnerability of sectors network.
