The Airline Container Loading Problem with Pickup & Delivery and Multi Doors

We address the problem of allocating containers into predefined positions of a carrier, in
this case aircraft, under several realistic structural and safety constraints, including the management of several doors. The originality of
our approach is to allow multi-trips with pickup and delivery at some intermediate locations.
The objective is to minimize the economic and environmental costs including the impact of
the intermediate operations. We resort to an integer linear model. Numerical experiments have
been performed using a standard B&C library. The cost impact is measured. The Airline Group of the International Federation of Operational Research Societies, composed of professionals and academics, has awarded us the price of the "Best technical presentation" for this work.
