Advanced algorithms for improved baggage handling

Abstract

According to SITA, customer satisfaction in airports depends heavily on the quality of baggage handling and the speed of delivery. Baggage handling infrastructure is, however, both costly and extremely space-consuming; hence, it is necessary to use the resources optimally. In this paper, we present strategies for optimising baggage processes in airports for outbound and inbound baggage. Outbound baggage is defined as baggage checked-in locally at curbside, transported to the airside by the baggage handling system (BHS), where it is sorted to a chute (lateral). Based on a case study, the authors introduce the idea of shifting the assignment strategy of chutes from a conventional build to a more handler-friendly compressed build. This is achieved without extending the baggage infrastructure, but by using advanced optimisation methods to allocate chute(s). Inbound baggage is baggage terminating in the airport after being reclaimed by the passenger. For inbound baggage, the process is different and based on batches. The paper is presenting an idea of how to use an optimised algorithm to allocate reclaim belts in the offloading facilities while improving the experience for passengers in the reclaim hall. The case studies are based on examples from Copenhagen Airport.
