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 or RFID)
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."
Random Location Storage
A storage technique in which parts are placed in any
space that is empty when they arrive at the
storeroom. Although this random method requires the
use of a locator file to identify part locations, it
often requires less storage space than a
fixed-location storage method. Also see:

Rate Based Scheduling
A method for scheduling and producing based on a
periodic rate, e.g., daily, weekly, or monthly. This
method has traditionally been applied to high-volume
and process industries. The concept has recently
been applied within job shops using cellular layouts
and mixed-model level schedules where the production
rate is matched to the selling rate
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.
Re-consignment
A carrier service that permits changing the
destination and/or consignee after the shipment has
reached its originally billed destination and paying
the through rate from origin to final destination.
Reorder point
A predetermined inventory level that triggers the
need to place an order. This minimum level provides
inventory to meet anticipated demand during the time
it takes to receive the order.
