Sequencing to multi-runway approach landing flights based on ACS

When air traffic congestion happens, the optimization adjustment on the order for approach landing flights can reduce the air traffic congestion and the flightspsila delay, improve the safety of flying, and reduce the economy cost. For the flights sequencing problem of multi-runway in the terminal area, the model was given according to the least total cost of flights delay, then the ant colony algorithm was developed to solve the sequencing problem for searching the optimization solution. By the actual data computation, and the compare with the result of FCFS sequencing algorithm, shows that the model provided has feasibility and validity.
