dc.description.abstract | We present two novel approaches to alter a flight network for introducing new flights while
maximizing airline’s profit. A key feature of the first approach is to adjust the aircraft cruise speed
to compensate for the block times of the new flights, trading off flying time and fuel burn. In the
second approach, we introduce aircraft swapping as an additional mechanism to provide a
greater flexibility in reducing the incremental fuel cost and adjusting the capacity. The nonlinear
fuel-burn function and the binary aircraft swap and assignment decisions complicate the optimization problem significantly. We propose strong mixed-integer conic quadratic formulations to
overcome the computational difficulties. The reformulations enable solving instances with 300
flights from a major U.S. airline optimally within reasonable compute times. | en_US |
