We investigate a problem on robust aircraft routings in order to improve their performance in operations. We perturb flight schedules by retiming departure or arrival times of flights, then, we characterize some schedule perturbations analytically. The robustness of aircraft routings can be increased by adding longer slack or flight times, and especially, if departure time of flights in aircraft routings is moved no longer than the change of departure time of prior flights. Based on the characteristics, we propose a new optimization model for retiming departure time of flights. The model is constructed to avoid dependence of the optimal solution on historical delay data. The computational results show that the model produces schedules that significantly improve overall schedule performance. © School of Engineering, Taylor's University
