Improvement of Warehouse Storage Area and System: An Application of Visual Control and Barcode

This action research aims to develop storage area and system in order to enhance picking efficiency, using a television manufacturer as a case study. Before improvement, random storage strategy was employed to store television in warehouse, without recording storage locations. This resulted lengthy searching and picking time, as well as incorrect picking to the customers. The concepts of visual control and barcode ware applied to improve storage area, put-away and picking methods. Consequently, picking time significantly reduces from average 72.0 to 43.0 minutes per requisition form, and picking error during three months decreases from 8 to 0 times.
