22.05 11:00 IDSIA B. Atasoy - Analysis of an itinerary-based airline fleet assignment model with choice-driven recapture and pricing

by Announcements of talks＠IDSIA

TITLE: Analysis of an itinerary-based airline fleet assignment model with choice-driven recapture and pricing SPEAKER: Bilge Atasoy, Transp-OR, EPFL, Switzerland DATE: Wednesday, May 22nd, 2013 PLACE: IDSIA, Seminar's room, Galleria 1 TIME: 11.00 ABSTRACT: 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.

16.05 1130 IDSIA - M. Klumpp - Green Logistics and Optimization in Delivery Schemes

by Announcements of talks＠IDSIA

Wednesday 16 May 2013, 1130 IDSIA meeting room, Galleria 1, Manno Green Logistics and Optimization in Delivery Schemes Prof. Dr. Matthias Klumpp Wissenschaftlicher Direktor ild Institut für Logistik- & Dienstleistungsmanagement FOM University of Applied Sciences Essen, Germany Abstract: 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.
