Analysis Service Process of Aircraft Turnaround Operations by Petri Net

Abstract

Airport collaborative decision-making has put forward higher requirements for aircraft turnaround operations. In order to improve the efficiency of aircraft turnaround operations, this paper improves the Petri net model based on the characteristics of MATLAB language. It gives the specific steps to analyze the influence of aircraft turnaround operations period on the apron flight viable service route. The experimental analysis shows that the change in passenger cabin cleaning, catering, and air bridge disconnecting within the routine service time does not affect the number of viable service routes and critical operations of aircraft turnaround service. Suppose the time of four operations, the bridge connecting, water clearing, passenger deboarding, and water filling, are respectively set in the interval [1.43, 1.98], [8, 8.7], [10.5, 11] and [8.1, 9.9], the number of viable service routes will only achieve two values. In that case, the bigger one is 4.7543 * 1076 with the 72% generating probability. The other is 3.5715 * 1076, which is 3.11 * 104 times as many as the minimum value obtained by the regular value interval of four operations, improving the quality of the minimum number of viable service routes. The results indicate that setting the time of some aircraft turnaround operations within a reasonable range will improve the number of viable service routes.
