London Heathrow airport is one of the busiest airports in the world. Moreover, it is unusual among the world’s leading airports in that it only has two runways. At many airports the runway throughput is the bottleneck to the departure process and, as such, it is vital to schedule departures effectively and efficiently. For reasons of safety, separations need to be enforced between departing air...

This paper describes an actual aircraft maintenance labor scheduling study. The study's objective is to determine the optimum maintenance workforce schedule to satisfy growing labor requirements with minimum cost. The main recommendation of the study is to switch from a five-day to a seven-day workweek for aircraft maintenance workers. A new integer programming formulation, used to obtain an op...

Batching jobs in a manufacturing system is a very common policy in most industries. Main reasons for batching are avoidance of setups and/or facilitation of material handling. Batch processing systems often consist of multiple machines of different types for the range and volumes of products that have to be handled. Building on earlier research in aircraft industry, where the process of hardeni...

Airport runways and taxiways have been identified as a key source of system-wide congestion and delay in the over-strained commercial air traffic system. To combat this growing problem, we present a novel approach for taxiway scheduling and traversal. Aircraft must traverse a taxiway, represented by a graph, from gates to their respective runways and arrive at their scheduled times while adheri...

Aircraft Engine Health Management Data Mining Tools is a project led by NASA Glenn Research Center in support of the NASA Aviation Safety Program's Aviation System Monitoring and Modeling Thrust. The objective of the Glenn-led effort is to develop enhanced aircraft engine health management prognostic and diagnostic methods through the application of data mining technologies to operational data ...

American Airlines currently operates in excess of 550 aircraft and flies over 2200 scheduled flights a day to over 160 destinations worldwide. Maintenance planning in a route network of American's magnitude is a complex, decision-intensive task that is managed at the Maintenance Operations Center (MOC) in Tulsa, Oklahoma. The employees in this center are responsible for planning all maintenance...

• Aircraft maintenance check scheduling optimization considering uncertainties. A tractable lookahead approximate dynamic programming (ADP) methodology is proposed. The ADP adopts a policy that uses deterministic and stochastic forecasts. makes decision its long-term impact. This paper proposes for aircraft scheduling, the uncertainty of daily utilization elapsed time. It framework, using hybri...
