Cross docking works as follows: the received goods are used at once to prepare the orders in the batch. However... goods enter unsorted. A sorting machine sorts the required numbers of the product in question directly to the individual order. The items not used in the batch are pre-sorted in the same round for the next batch(es). The pre-sorted goods are therefore guided over the sorter again with the next batch, but entering them again is always quicker than picking and sorting them out again. It is also possible to sort the items that have not been assigned to an order in the batch to a stock position. At the end of the process the totals offer an accurate summary of the number of received goods. Inter-branch traffic or shop-to-shop logistics in a distribution centre function in the same way.
