Robustness Analysis of Flight Conflict Networks Based on Degree Correlation

Analyzing the composition and robustness of flight conflicts is beneficial to find vulnerable sources dissipate conflicts, effectively improve safety operational efficiency air traffic. Therefore, this paper proposes a conflict network evaluation method based on degree correlation. Firstly, constructed by using velocity obstacle method, it classified into three types assortative, disassortative neutral networks according correlation network. Several common metrics in complex are explored, comprehensive metric proposed. The relationship between under different node removal methods analyzed simulation experiments. results show that false alarm rate decreased 37.5% compared with traditional state closely related robustness. assortative demonstrate stronger vulnerability betweenness removal, respectively, more obvious vulnerability. does not differ significantly two methods. Compared random deletion, target can decrease
