AN AIRLINE FLEET PLANNING MODEL

An extended fleet planning model is presented as a linear program which solves for maximum income for the airline system given future passenger demand on the route structure, a forecast of competitive frequencies, and a determination of market share for a given frequency. In this case, future revenue yields, future marginal operating costs, and future ownership or leasing costs are related to maximize the present value of future income. The model is solved for several time periods into the future, and an expression for fleet continuity throughout the period is used. The model introduces buying, selling and leasing options for determing an optimal fleet planning strategy for the system over the complete period. The fleet assignment on the route structure is also determined. Indicated are various methods for modelling typical restrictions on buying or selling, representing available leases or relating trade-in or lease purchase arrangements. The uses of the model for both the airlines and aircraft manufacturers is discussed. A discussion is included on the use of decomposition methods of linear programming to solve the model.
