Grunow et al. [58,59] focus on dispatching multi-load AGVs. A flexible priority rule based approach is proposed and compared to an altemative MIP formulation in different scenarios. Reduction of AGVs’ lateness in case of multi-load mode is shown and an improvement of the terminal’s overall performance is expected. In addition, a MIP is developed that allows determining optimal solution for small problem instances. For real applications a hybrid approach using the MIP combined with fast heuristics on some special dispatching requests is suggested. A different MIP formulation can be found in [172].
