dc.description.abstractUnit Load Devices (ULDs) are standard equipment for loading baggage and cargo in airplanes. The maintenance of one's own ULD stock is a non-negligible cost factor for airlines. In recent years, therefore, many airlines have outsourced the management of their ULD's to independent ULD providers. The independent ULD providers should be able to pool the individual ULD stocks and therefore manage the ULD demand with less stock. As part of an applied research project, we developed for an ULD provider decision support: - To determine the daily ULD safety stock levels at a station in order to guarantee a service level for a fixed planning horizon, and - To control safety stock levels at the stations by balancing empty ULD’s between the stations. For the daily safety stock level we built a Monte Carlo simulation which is based on historical data. Extensive live tests showed that our safety stocks work reliable in daily operations. The approach to determine the daily safety stock levels will be discussed shortly. The focus of this talk is on the modelling of the decision support for the ULD control. A linear optimization model was built to control the empty ULD movements. The objective was to balance the ULD stock between the stations and to guarantee enough ULD’s for daily operations. Since we work with a linear model, we are able to compute solutions for huge airline networks in reasonable time. We will present test results of the implemented ULD control for an existing airline network.de_CH
