Aviation Network Repair under Airport Failure Based on a Modified PSO Algorithm

When the airport node is faced with deliberate attacks and natural disasters, it is easy to be destroyed, which makes the air traffic disorder and affects the entire aviation network. Therefore, a network repair method based on Particle swarm optimization (PSO) algorithm under the condition of airport failure is proposed. In this repair method, distance cost and Mid-air collision risk cost are first considered, and the network repair problem of airport failure is described as a constrained optimization problem; Then, improve the standard PSO algorithm; Finally, an improved PSO algorithm is used to solve the constrained optimization problem. Simulation shows that this method has fast convergence, strong practicality, and is easy to implement.
