| Rack-supported building

|
| Radio frequency
|
|
In warehousing, refers to the portable data collection devices that use radio frequency (RF) to transmit data to host system.
|
|
|
| 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 terminal can be placed at a fixed station, mounted on a forklift truck, or carried in a worker's hand. The base station contains a transmitter and receiver for communication with the terminal. 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 combines with a bar code system of identifying inventory items, a radio frequency system can relay data instantly, thus updating inventory records in so-called real time.

| Reach truck
|
|
A.k.a. Stand-up reach, straddle reach , double-deep reach. The reach truck is a narrow-aisle (8'-10') lift truck designed specifically for racked pallet storage. It consists of outriggers in front and telescoping forks that use a hydraulic scissors-type mechanism that allow you to pick up the load and retract it over the outriggers reducing the overall truck and load length, allowing you to turn in a narrower aisle. Double-deep reach trucks use an extended reach mechanism that allows you to store pallets two-deep in specially designed double-deep rack. Reach trucks are designed for racking areas only and do not work for loading trucks or quickly moving loads over distances. Also see lift truck pics and lift truck basics for more info.

| Real Time
|
|
The processing of data in a business application as it happens, as contrasted with storing data for input at a later time (batch processing).
|
|
|
| Real-time locator system
|
|
Real-time locator system (RTLS) uses RFID technology that provides the objects they are attached to the ability to transmit their current location. System requires some type of RFID tag to be attached to each object that needs to be tracked, and RF transmitters/receivers located throughout the facility to determine the location and send information to computerized tracking system. While it sounds like a great way to eliminate "lost" inventory, the systems are still too costly for most inventory tracking operations and are more likely to be used to track more valuable assets.

|
| Reorder point
|
|
The inventory level set to trigger reorder of a specific item. Reorder point is generally calculated as the expected usage (demand) during the lead time plus safety stock. Fixed reorder point implies the reorder point is a static number plugged into the system. Dynamic reorder point implies there is some system logic calculating the order point. Generally this would be comparing current inventory to the forecasted demand during the lead time plus safety stock.

| RFID
|
|
Radio frequency identification. Refers to devices attached to an object that transmit data to an RFID receiver. These devices can be large pieces of hardware the size of a small book, like those attached to ocean containers, or very small devices inserted into a label on a package. RFID has advantages over barcodes, such as the ability to hold more data, the ability to change the stored data as processing occurs, does not require line-of-site to transfer data and is very effective in harsh environments where bar code labels won't work.
