The retrieval algorithm utilizes criteria that include SKU classification, UOM and zones, and sequencing strategies. The algorithm retrieves products from eligible locations in a warehouse and employs either the 'pick to clean' or 'least pick' methods. The following figure illustrates the retrieval algorithm.
The business process configuration and algorithm answers the following questions:
Retrieve to location corresponding to department that places request automatically or manually through move request. For example, VAS requesting for component inventory.
Retrieval strategy values to determine the optimal zones to search for based on item classification and UOM.
'Pick to clean' method indicates that the system optimizes on a location becoming empty after quantity is retrieved, while also considering the least amount of locations to pick from.
'Least Pick' method indicates the system optimizes on the least number of locations that satisfy the retrieval quantity.
