Rack: A storage device for handling material in pallets. A rack usually provides storage for pallets arranged in vertical sections with one or more pallets to a tier. Some racks accommodate more than one-pallet-deep storage. Some racks are static, meaning that the rack contents remain in a fixed position until physically moved. Some racks are designed with a sloped shelf to allow products to “flow” down as product in the front is removed. Replenishment of product on a flow rack may be from the rear, or the front in a “push back” manner.
Radio Frequency (RF): A form of wireless communications that lets users relay information via electromagnetic energy waves from a terminal to a base station, which is linked in turn to a host computer. The terminals can be place at a fixed station, mounted on a forklift truck, or carried in the worker's hand. The base station contains a transmitter and receiver for communication with the terminals. RF systems use either narrow-band or spread-spectrum transmissions. Narrow-band data transmissions move along a single limited radio frequency, while spread-spectrum transmissions move across several different frequencies. When combined with a bar-code system for identifying inventory items, a radio-frequency system can relay data instantly, thus updating inventory records in so-called "real time".
Radio Frequency Identification (RFID): The use of radio frequency technology including RFID tags and tag readers to identify objects. Objects may include virtually anything physical, such as equipment, pallets of stock, or even individual units of product. RFID tags can be active or passive. Active tags contain a power source and emit a signal constantly. Passive tags receive power from the radio waves sent by the scanner/reader. The inherent advantages of RFID over bar code technology are: 1) the ability to be read over longer distances, 2) the elimination of requirement for “line of sight” reads, 3) added capacity to contain information, and 4) RFID tag data can be updated/changed.
Raw Materials (RM): Crude or processed material that can be converted by manufacturing,
processing, or combination into a new and useful product.
Receiving: The function encompassing the physical receipt of material, the inspection of the incoming shipment for conformance with the purchase order (quantity and damage), the identification and delivery to destination, and the preparation of receiving reports.
Receiving Dock: Distribution center location where the actual physical receipt of the purchased material from the carrier occurs.
Refrigerated Carriers: Truckload carriers designed to keep perishables good refrigerated. The food industry typically uses this type of carrier.
Reefer: A term used for refrigerated vehicles.
Regional Carrier: A for-hire air carrier, usually certificated, that has annual operating revenues of less than $74 million; the carrier usually operates within a particular region of the country.
Retailer: A business that takes title to products and resells them to final consumers. Examples include Wal-Mart, Best Buy, and Safeway, but also include the many smaller independent stores.
