There is an increasing interest for the integration of supply-demand
interactions in airline schedule planning models. We work with an
itinerary-based airline fleet assignment model where an itinerary choice
model is explicitly integrated. The choice model represents the decision
on pricing as well as the spill and recapture effects. We present a
sensitivity analysis for the key assumptions of the demand model in
order to quantify the added value of the choice-based fleet assignment.
The model is solved with a local search heuristic which iterates over
two sub-problems. We present a set of reformulations as a
convexification of the revenue sub-problem which is expected to
increase the efficiency of the solution methodologies.

From prejudiced logistics concepts in green logistics an increased safety stock level decision making is expected (Green Bullwhip Effect).
This could be shown experimentally by providing optimal solutions in a Monte-Carlo-Setting for different delivery schemes (standard, green) under inclusion of uncertain demand.
