Abstract
We propose a hierarchical control framework for state-of-the-art baggage
handling systems where the luggage is transported by fast destination coded
vehicles (DCVs). In this control framework switch controllers provide position
instructions for each switch in the network. A collection of switch controllers
is then supervised by a network controller that mainly takes care of the route
choice instructions for DCVs. The route choice control problem is problem is a
nonlinear, mixed integer optimization problem, with high computational
requirements, which makes it intractable in practice. Therefore, we present an
alternative approach for reducing the complexity of the computations by
approximating the nonlinear optimization problem and rewriting it as a mixed
integer linear programming (MILP) problem for which solvers are available that
allow us to efficiently compute the global optimal solution. The solution of
the MILP problem is then used in computing optimal switch control actions. For
a benchmark case study we compare the hierarchical control with centralized
switch control. The results indicate that the proposed hierarchical control
offers a balanced trade-off between optimality and computational efficiency.
