Abstract
The process of handling baggage in an airport is time-critical. Currently, the
fastest way to transport the luggage is to use destination coded vehicles
(DCVs). These vehicles transport the bags at high speed on a "mini" railway
network, but their route has to be controlled in order to ensure the system
optimum. In this paper we determine an event-based model of a DCV-based baggage
handling system and we compare centralized and decentralized approaches for
routing the DCVs through the network. The proposed centralized control methods
are optimal control and model predictive control (MPC). Due to the large
computation effort required, we also analyze a fully decentralized control
approach. In this case, each junction has its own local controller for
positioning the switch into the junction or out of it, routing the DCVs through
the network. The local controllers do not communicate their actions. The
considered control methods are compared for several scenarios. Results indicate
that optimal control becomes intractable when a large stream of bags has to be
handled, while MPC can still be used to suboptimally solve the problem.
However, the decentralized control method usually gives worse results to the
ones obtained when using MPC, but with very low computation time.
