Stochastic optimization models for airline resource schedules under disruptions

Coauthor: Natalia Kliewer

 

Abstract:
In this talk we compare two stochastic models considering the robustness and cost-efficiency of airline resource schedules. The first model deals with the delay absorbing capacity of schedules, the second with the recoverability during operations. These two aspects can be called stability and flexibility. Both models are solved by a branch-and-price&cut-algorithm. The resulting schedules are evaluated by an event-based simulation including a delay propagation model and a rule-based recovery approach. This enables us to identify possible mutual impacts, e.g., if stable schedules still offer the same degree of swap opportunities for operational recovery and vice versa.
The presented analysis is a pre-step to an integrated stochastic approach for considering both stability and flexibility aspects at the same time during scheduling.
