| Abstract |
Several months ago, Ruud Stegers introduced a topic to the WAI audience about economic fuelling of a particular type of aeroplane, the Fokker 70. At that point, he could only introduce the problem but there was no solution yet. In the WAI talk on Monday, Said Ait Haddou Ou Ali, who worked on the problem while three people from the VU helped him with ideas, will present the results of the project. This is what he is going to talk about:
This presentation is about KLM Cityhoppers (KLC) optimization efforts in the field of economic fuelling. Economic fuelling is the process in which profit is increased by filling the plane with fuel at its base station (Schiphol) for the flight to the destination, as well as with fuel for the flight back to the base station. This usually increases profit, because fuel prices at other stations are much higher. When economic fuelling is applied a large amount of super cooled fuel remains in the wing tanks upon arrival at the destination airport. This increases the risk of ice forming on the wings significantly and, with that, an expensive deicing treatment. A logistic regression model is used to predict the deicing probability and the risk involved. With the risk quantified, one can choose the optimum economic fuel amount which maximizes profit taking the deicing risk into acount. A scenario analysis, using historical data, shows that this model increases profit with more than 20% with respect to the currently used fuelling policy. |
