Inherent delays and operational reliability of airline schedules
نویسنده
چکیده
This paper explores the inherent delays of airline schedules resulting from limited buffer times and stochastic disruptions in airline operations. The reliability of airline schedules is discussed and a set of measuring indices is developed to evaluate schedule reliability. It is found that significant gaps exist between the real operating delays, the inherent delays (from simulation) and the zero-delay scenario. Delay propagation and its impact on schedule reliability are also discussed. Results show that airline schedules must consider the stochasticity in daily operations. Schedules may become robust and reliable, only if buffer times are embedded and designed properly in airline schedules. r 2005 Elsevier Ltd. All rights reserved.

Improving Airline Network Robustness and Operational Reliability by Sequential Optimisation Algorithms
A sequential optimisation algorithm is developed to improve the operational reliability of airline schedules. Simulation results show that departure delays are reduced by 30% after optimisation by using extra 260 min buffer times in the schedule. This also increases the network-wide schedule reliability from 37 to 52% and an estimated delay cost saving of $20 million dollars per annum for a sma...
متن کاملRethinking Human-Centered Computing: Finding the Customer and Negotiated Interactions at the Airport
During the late 1990s and into 2001, tightly coordinated airline schedules unraveled due to massive delays that were the result of inclement weather, over booked flights and airline operational difficulties. As schedules slipped, the delayed departures and late arrivals resulted in system breakdowns, customers who missed their connections, and airline work activities that fell further out of sy...
متن کاملA multi-objective approach for robust airline scheduling
We present a memetic approach for multi-objective improvement of robustness influencing features (called robustness objectives) in airline schedules. Improvement of the objectives is obtained by making minor incremental changes to the flight schedule by retiming the flights and the aircraft rotations, subject to a fixed fleet assignment. Approximations of the Pareto optimal front are obtained b...
متن کاملImproving airline operational performance through schedule perturbation
Schedule development is typically the first phase of the airline planning process. We present a framework for perturbing scheduled departure and arrival times after a crew schedule has been found. We characterize perturbations that keep a schedule legal while not increasing the planned cost of the crew schedule. We show that when random delays occur in operations, the expected cost can be reduc...
متن کاملHeuristic approach to the airline schedule disturbances problem
When disturbances make it impossible to realise the planned flight schedule, the dispatcher at the airline operational centre defines a new flight schedule based on airline policy, in order to reduce the negative effects of these perturbations. Depending on airline policy, when designing the new flight schedule, the dispatcher delays or cancels some flights and reassigns some flights to availab...
