This system is particularly useful for maximizing storage space in the warehouse and improving retrieval times. |
The ASRS is connected to the WMS, which provides real-time data on stock levels and order priorities. When an item needs to be retrieved, the WMS sends a request to the ASRS, which then locates the item in the storage area and retrieves it for further processing. The system can also be programmed to optimize the arrangement of items in the warehouse, ensuring that frequently ordered products are stored in easily accessible locations, while less frequently ordered items are placed in harder-to-reach areas. |
3.5 Workflow Automation |
The integration of these automated systems allows for the automation of many aspects of warehouse workflows. For example, once an order is placed, the WMS analyzes the order and generates instructions for the robots to pick the required items. The robots then navigate the warehouse, retrieve the items, and transport them to a central packing area. This minimizes the need for human intervention, reducing the chances of errors and speeding up the fulfillment process. |
The workflow automation also extends to inventory tracking and replenishment. As the barcode scanning robots continuously monitor stock levels, the system automatically updates the inventory records in the WMS.
