Dematic’s PickDirector 3.6 WCS (Warehouse Control System) manages order fulfillment activities in piece or case pick applications using RF, light displays or voice technologies to optimize processes and direct warehouse staff. It is often configured to operate in conjunction with picking carts or smart conveyor networks and supports "pick" or "put" applications. This software extends functionality to include enhanced operation with "put walls" and order packing work cells. It also drives hybrid fulfillment operations such as indexing or constant pace conveyor systems that are designed to maximize picking productivity. PickDirector 3.6 supports all types of warehouse environments from non-automated operations where no racking or location codes exist to automated/mechanized system configurations.
