Air traffic dependent network vulnerability identification and control method and system

Abstract

The invention provides an air traffic dependent network vulnerability identification and control method and system. According to the method and the system, firstly, an air traffic dependency network model connected by airport network, airway network and control sector network is established; disturbance strategies of random disturbance and deliberate disturbance are used for disturbing nodes of the air traffic dependent network; calculating a change rate of a structure vulnerability related characteristic index and a change rate of a function vulnerability related index of the dependent network; and identifying a change rule of the structure vulnerability and the function vulnerability of the dependent network, and finally, optimizing the vulnerability of the dependent network by performing flow coordination control on the dependent network according to an identification result. In combination with the vulnerability analysis result of the air traffic dependency network, the traffic flow of the network is subjected to coordination control again, so that the traffic flow of the air traffic dependency network tends to be ordered, and the vulnerability of the network is reduced.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, and in particular relates to a method and system for identifying and controlling the vulnerability of an air traffic dependent network. Background technique [0002] When the air traffic system is in operation, it often encounters internal or external disturbances of the system (such as flight take-off and landing queues caused by unreasonable airport time, bad weather or military activities that cause the capacity of airport routes to decrease, etc.), resulting in a decline in the performance and efficiency of air traffic flights. This leads to the vulnerability of the system. The performance of the vulnerability of the air traffic system not only threatens the safety of the air traffic system, but also destroys the normal flight transportation function of the system, so the research on the identification and control of the vulnerability of the air traffic system has positive prac...

Problems solved by technology

In the related air traffic interdependence network research, the fault propagation law among multi-layer networks and the vulnerability of interdependence networks have been studied, but there is little research on the identification and control of the vulnerability of air traffic interdependence networks
