Itinerary-based airline fleet assignment
The fleet assignment problem is to determine an optimal assignment of aircraft types to flight legs in a specified flight network. The assignment process must trade off the operating costs of large capacity aircraft with the lower operating costs, but potentially large amount of lost revenue, …

Airline fleet assignment and schedule design : integrated models and algorithms
… generation process, namely, schedule design and fleet assignment. The schedule design problem involves selecting an optimal set of flight legs to be included in the schedule, while the fleet assignment problem involves assigning aircraft types (or fleets) to flight legs to maximize revenues and …

Discrete Two-Stage Stochastic Mixed-Integer Programs with Applications to Airline Fleet Assignment and Workforce Planning Problems
… of SMIP to enhance the traditional airline fleet assignment models (FAM). Given a flight schedule network, the fleet assignment problem solved by airline companies is concerned with assigning aircraft to flight legs in order to maximize profit with respect to captured path- or …

Revenue management under demand driven dispatch
… maximizing way. Current algorithms for dynamic reassignment of aircraft types suggest that the nect assignment problem be solved repeatedly during the booking horizon of the pool of flights being considered in the type assignment model. This approach has been shown to produce a 1% to 5% …

Degradable airline scheduling : an approach to improve operational robustness and differentiate service quality
… process: (1) between flight scheduling and fleet assignment (degradable schedule partitioning model), (2) with fleet assignment (degradable fleet assignment model), and (3) with aircraft routing (degradable aircraft routing model). Each problem is modeled as an integer program. Search …

Cyclic exchange and related neighborhood structures for combinatorial optimization problems
… second part deals with the Combined Through and Fleet Assignment Model (ctFAM). This model integrates two airline planning models: (i) Fleet Assignment Model and (ii) Through Assignment Model, which are currently solved in a sequential manner because the combined problem is too large. This leads …

Integrated optimization model for airline schedule design : profit maximization and issues of access for small markets
… model combines an Integrated Schedule Design and Fleet Assignment model and a model, based on Passenger Decision Window model, that determines passenger preference for itineraries. We simultaneously establish frequency, departure times, fleet assignment, passenger loads and revenue within a …

Incremental airline schedule design
… of integrating flight schedule design and fleet assignment decisions at airlines. The flight schedule design problem involves selecting and scheduling the set of flight legs that an airline will include in its service network. Fleet assignment involves assigning a particular aircraft type …

Integrated Aircraft Fleeting, Routing, and Crew Pairing Models and Algorithms for the Airline Industry
… of four decision stages: schedule planning, fleet assignment, aircraft routing, and crew scheduling. The outputs of this process are flight schedules along with associated assignments of aircraft and crews that maximize the total expected profit. Traditionally, airlines deal with these four …

Global Commercial Aircraft Fuel Burn and Emissions Forecast: 2016 to 2040
… (surrogate of demand) by OD airport pair, c) the fleet evolution over time, d) fuel consumption by OD pair and aircraft type, and emissions by OD pair and aircraft type. The model has developed an airline fleet assignment module to predict changes to the airline fleet in the future. Specifically, …

Robust airline schedule planning : review and development of optimization approaches
… constraints involving flight schedule design, fleet assignment, aircraft maintenance routing and crew scheduling. Almost all aircraft and crew schedule optimization models assume that flights, aircraft, crews, and passengers operate as planned. Thus, airlines typically construct plans that …

Air Transportation Modeling to Evaluate Airport Runway Infrastructure and Supersonic Transport Demand
… open-loop systems to assess worldwide demand and fleet size of future supersonic aircraft designs, assuming a fixed percentage of business passengers willing to switch to supersonic travel (i.e., switch rate). However, these studies overlooked the strong causality between supersonic transport …

Demand driven dispatch and revenue management
… environment. Demand driven dispatch is the reassignment of aircraft to flights close to departure to improve operating profitability. Previous studies on demand driven dispatch have not incorporated competition and have typically ignored or significantly simplified revenue management. All …

Airline scheduling and air traffic control : incorporating uncertainty and passenger and airline preferences
… logit choice model and integrate it into a fleet assignment and schedule design model. To tackle the formidable computational challenge associated with solving this model, we develop a reformulation, decomposition and approximation scheme. Using data from a major U.S. airline, we prove that …
