An interacting structure of people, equipment, and procedures which together make relevant information available to the logistics manager for the purposes of planing, implementing and control.

Technologies in LIS

Bar code Point-of-Sale ( POS) EDI RF-RFID

23

Bar Coding

barcodes stored data in series of parallel black and white bars of various widths and spacing. They can be read by optical scanners called barcode readers or scanned from an image by special software.

Contemporary Logistics Information Technologies

The Universal Product Code (UPC) is a specific type of barcode, that is widely used in the United States and Canada for tracking trade items in stores.

Point of Sales Data

Technology that allows firms, in real time, to know what and where an item is being sold through scanning of individual barcodes when an item purchased at the retail level.

Using this information, product forecasting, make better purchase decision and customization, and reduce the chance that an item will be out of stock.

RFID

RFID system consists of an antenna and a transceiver, which read the radio frequency and transfer the information to a processing device, and a transponder, or tag, which is an integrated circuit containing the RF circuitry and information to be transmitted.

RFID systems can be used just about anywhere, from clothing tags to missiles to pet tags to food -- anywhere that a unique identification system is needed.

29

Radio Frequency Identification (RFID)

Item-level tracking Automatic Non-Line-of-Sight Scanning

30

RFID tags come in three general varieties: passive, active, or semi-passive (also known as battery-assisted).

Passive tags require no internal power source-only active when a reader is nearby to power them, whereas semi-passive and active tags require a power source, usually a small battery.

Passive tags have practical read distances ranging from about 10 cm (4 in.)

31

Active Tags Active tags typically have much longer range and

larger memories than passive tags, as well as the ability to store additional information sent by the transceiver.

Some active RFID tags include sensors such as temperature logging which have been used to monitor the temperature of fresh produce or certain pharmaceutical products.

Other sensors that have been married with active RFID include humidity, shock/vibration, light, radiation, temperature, and atmospherics like ethylene.

32

Semi-passive Tags Semi-passive tags are similar to active tags in that

they have their own power source, but the battery only powers the microchip and does not broadcast a signal.

The RF energy is reflected back to the reader like a passive tag. An alternative use for the battery is to store energy from the reader to emit a response in the future.

Greater sensitivity than passive tags, typically 100 times more.

33

Radio Frequency (RF)

Relay information via electromagnetic energy waves from a terminal to a base station, which is linked in turn to a host computer.

Contemporary Logistics Information Technologies

Typically used in a warehouse or distribution center, RF technologies provide the communications capability between operating personel (e.g. Fork lift drivers, loading dock personnel, etc.) and centralized computer capabilities.

34

Definition of EDI Inter organizational, computer-to-

computer exchange of business data in a standard, machine-processable format.

Unstructured Structured

Fax EDIE-Mail Order entryPerson-to-person Computer-to-computer

35

The purpose of EDI is to eliminate dublicate data entry and to improve thespeed and accuracy of information flow

by linking computer applications between companies.

Definition of EDI

Levi’s-integrated its customer order processing system using a

QR(quick response)-EDI: LeviLink

Transfer of structured data, by agreed message standards from one computer system to another without human intervention.

Definition of EDI

37

Types of EDIs

Proprietary Systems (One to Many) involve an EDI system which is owned, managed, and maintained by a single company

Value-added Networks (Many to Many) includes a third party firm that acts as a central clearinghouse

Industry Associations have their own EDI standards

38

For EDI to function properly, computer language compatibility is required.

Users must have common communication standards.

Trading partners must have common definition words, codes and symbols; and a common format and order of transmission.
