Pick-to-Light is considered to be the fastest operator-based picking method for broken case fulfillment operations. Due to a variety of available light-guided displays and pick strategies such as batch or single line, PTL can bring together various A, B, and even C product categories under one common operating system. PTL drives high pick rate productivity, accuracy and cost efficiency by reducing walk time, eliminating reading errors and by providing managerial oversight of work performance. These paperless systems use LEDs mounted to shelving, flow rack, work benches, pallet rack, carts, or other storage locations. Whenever product is needed from a particular location, the associated LED turns on, drawing attention where action is required. The operator picks the product quantity displayed. The operator then confirms the pick by pressing the lighted button.
