Abstract
This paper presents a unified and extended account of previous work regarding
modern baggage handling systems that transport luggage in an automated way
using destination coded vehicles (DCVs). These vehicles transport the bags at
high speeds on a network of tracks. To control the route of each DCV in the
system we first propose centralized and distributed predictive control methods.
This results in nonlinear, nonconvex, mixed-integer optimization problems.
Therefore, the proposed approaches will be expensive in terms of computational
effort. As an alternative, we also propose a hierarchical control framework
where at higher control levels we reduce the complexity of the computations by
simplifying and approximating the nonlinear optimization problem by a
mixed-integer linear programming (MILP) problem. The advantage is that for MILP
problems solvers are available that allow us to efficiently compute the global
optimal solution. To compare the performance of the proposed control approaches
we assess the trade-off between optimality and CPU time for the obtained
results on a benchmark case study.
