5.1.4 Warehouse information systems

Information technology (IT) has provided to the warehousing process several benefits, such as improved customer service, efficient operations and lower costs. These benefits flow from a warehouse's various IT interfaces in receiving, storing, shipping, order processing, packaging and quality control. Some of the IT used in warehouses today are electronic data interchange (EDI), automatic data collection (ADC) and radio frequency (RF).

Electronic data interchange refers to the exchange of machine-readable data in a standard format between workstations that belong to different firms engaged in the integrated logistics process. Effectively, EDI creates paperless transactions and this has several advantages as compared to the traditional paper-based method.

Automated data collection uses computer technology to capture data using machine-readable bar codes and scanners. This has potential benefits ranging from lower inventory costs to better overall quality control in the warehouse.

Radio frequency is comprised of terminals, network controllers and radio frequency units. The terminals can be hand held, vehicle mounted or fixed collectors of data. The radio frequency units are transmitters/receivers that communicate with the terminals. A RF system is a series of antennas placed under the roof of the warehouse (Bloomberg, Murray & Hanna 1998). This system when used in the warehouse has several benefits, some of which are increased productivity, decreased errors, better utilisation of space, better control of stock rotation and improvement in overall customer service.
