| Abstract | The airline scheduling used by today's major airlines, aims to develop optimal schedules
that minimizes costs, or alternatively maximizes revenue. However, these schedules are
often deviate from optimal solution once applied in the real world since they do not
accurately take into account possible weather, air traffic control (ATC), and other
disruptions that can occur during operation. The resulting flight delays and cancellations
can cause significant cost burden, not to mention service disruptions and customer
dissatisfaction. A novel approach to address this problem is to design schedules which
incorporate predictions of such disruptions into the design phase, would be a good
contribution.
In this research, added interest was given on optimization of an airline scheduling by
considering the trade off between cost of buffer time and delay. The model was developed
to obtain an optimal fleet assignment considering the trade off situation and the effect of
fleet mix. This model was tested on a test network selected from Japanese domestic
network and data gained from Japanese airline industries with the help of Genetic
Algorithm searching technique in the MATLAB 6.5. This model can be considered as a
simple variant of basic fleet assignment model with modified cost function, where cost
incurred from buffer time and delay were included.
The model developed in this study can be used to any network size and any fleet size. The
model was tested on four nodes-two fleet and four node-single fleet sized problems and the
solution was compared with another integer program technique of Best Subset Selection
method. The solutions found from the both method exactly coincided. The main output of
this model is optimized fleet assignment - a series of daily network that each aircraft
placed. The model can also be used to compare the cost effectiveness for different network
and fleet size while considering the trade off situation between the cost of buffer time and
delay. |
