Abstract:

To guarantee flight punctuality rate and evaluate the cooperative conditions of ATC, airlines and airport in flight scheduling process, we propose an evaluation model of flight collaborative scheduling to guarantee flight punctuality rate. The model establishes the index system of flight collaborative scheduling based on flights' average deviation value of arrival time, average deviation value of departure time, average deviation value of flight service completion time, the accuracy rate of ‘Target OffBlocking Time’, and the accuracy rate of ‘Calculate TakeOff Time’. Firstly, the impact thresholds of each index on flight cooperative scheduling or flight delay are determined through the association rule mining method. Then, the magnitude evaluation of each unit’s coordination in the process of flight collaborative scheduling is given through the combination of the fuzzy analytic hierarchy process and the comprehensive evaluation method. Experimental results show that the proposed model can evaluate the coordination of each unit in the process of flight scheduling scientifically and effectively, and it has great significance for optimizing flight security as well as improving the flights’ normal releasing rate.
