Pick-to-light systems provide a fast and accurate way to do which of the following?

Pick-to-light systems are a type of order-fulfillment technology used in warehouses to increase picking efficiency and accuracy. The system uses lights and LED displays at storage locations to guide a picker to the correct item and specify the quantity to be picked. After the operator picks the item, they press a confirmation button, which verifies the pick, turns off the light, and sends a real-time update to the Warehouse Management System (WMS). This confirmation step is a core function that automatically verifies the pick has been completed.

A. calculate lighting brightness: This is a function of environmental lighting systems or photometry, not a warehouse order-picking technology.

C. interface information to truck drivers: This is typically handled by a Transportation Management System (TMS) or a Yard Management System (YMS), not an internal picking system.

D. select house lighting schemes: This relates to building automation or interior design and is completely unrelated to logistics or warehouse operations.

In Chapter 6, "Order-picking," Section 6.4.2, "Picker-to-part systems," the text explains: "After picking the required quantity, the picker presses a button to confirm the pick, which extinguishes the light and updates the warehouse management system." This confirmation is the verification process. (Available at: www.warehouse-science.com)

In Section 3.1, "Order picking systems," the authors describe pick-to-light functionality: "After picking the items, the picker pushes a button on the display device to confirm the activity." This act of confirmation serves as the verification of the pick. (DOI: https://doi.org/10.1016/j.ejor.2006.07.009)
