Abstract
Autonomous vehicle-based storage and retrieval systems are used in order to supply picking or production areas based on the goods-to-person principle. In these contexts, it is often required that the point-of-use has to be supplied in a specific sequence of the retrieval loads. This sequence is normally established in the pre-storage area. Depending on the system configuration of an autonomous vehicle-based storage and retrieval system, it is possible to establish the required sequence at every input/output location directly out of the system. In order to enable this retrieval-in-sequence, we present an efficient algorithm that is based on the time-window routing method. For the purpose of evaluation of the performance, we implemented the algorithm in a simulation environment and conducted a series of simulation experiments.
