Trang 2Chapter 1: Logistics Information System
Overview
1.1 Some words about Logistics:
implementing, controlling the efficient & effective flow of
goods, services and related information from the point of origin
to the point of consumption for the purpose of conforming to
Trang 3❑ Information is a collection of data organized in such a way that they have
additional value beyond the data themselves
❑ Process is a set of logically related tasks performed to achieve a defined
outcome

❑ Information should be viewed as processed data which has been placed in a
context that gives it value for specific end users
1.2.1 Data v.s Information:
❑ Data structure:
Trang 41.2.1 Data v.s Information:
❑ Knowledge is an understanding of a set of rules that are followed to convert
data into information and how that information can be made useful to support a
specific task

2.1 Electronic Data Interchange (EDI):
2.1.1 EDI Overview:
Electronic Data Interchange is the transfer of business data between computer
applications using a mutually agreed standard to describe the data contained in the
Trang 102.1.1 EDI Overview:
28
2.1.1 EDI Overview:
❑ Benefits of EDI:
✓ Reduction of data entry errors
✓ Quick updates of information
✓ Cost saving & Increased efficiency
✓ Increased communications between supplier and consumer
✓ Improvements in business process
✓ Information in electronic forms is easily shared over the organization
…
Trang 112.1.2 EDI Components:
❑ Communication: Transportation of the EDI file over a network can be done in
many ways Any network and any protocol can be used as long as it fits the
needs Two types of communication are discussed here:
✓ Internet (AS1, AS2, FTP, etc.)
✓ Value-added network (VAN)
31
2.1.2 EDI Components:
❑ EDI format: The most commonly used message standard are:
▪ ANSI ASC X12 – US standard
▪ EDIFACT – recommended by United Nation
▪ UNTDI – UK retail standard
Trang 12Common X12 standard EDI documents include:
204 Motor Carrier Load Tender
210 Motor Carrier Freight Details and Invoice
214 Transportation Carrier Shipment Status Message

Common X12 standard EDI documents include (cont.):
856 Advance Ship Notice
860 Purchase Order Change
861 Receiving Advice
864 Text Message
865 Purchase Order Change Acknowledgment
869 Order Status Inquiry
Trang 152.1.3 EDI Implementation:
❑ Cost considerations:
The most important thing to consider is the bottom line - how much your
system will cost to implement and maintain versus how much increase in revenue
you will generate with your system
If you do a large amount of EDI transactions on a daily basis with many of
your customers, then you will want to invest in a system that has a high level of
automation Otherwise, you will be able to use an online service
Trang 16Yeah, I can do it.
2.2 Radio Frequency Identification (RFID):
2.2.1 RFID definition:
Radio frequency identification (RFID) is a generic term that is used to describe a
system that transmits the identity of an object or person wirelessly, using radio
waves
48
Why do we use RFID instead of Barcode???
Trang 172.2.2 Elements of an RFID System:
RFID systems fundamentally consist of two main elements:
• RFID tag (transponder)
• RFID reader/writer
49

- RFID systems are operated at widely differing frequencies, ranging from 135kHz
long wave to 5.8GHz in the micro wave range
- The achievable range of the system varies from a few milimetres to above 15m
• Close coupling system (up to 1 cm)
• Inductive radio system (up to 1 m)

2.2.3 Near field communication (NFC):
▪ The tags you see or create include contacts, URLs, map locations, text and much
more
▪ NFC is a short-range wireless technology that allows
communication between NFC enabled objects over a
distance of less than 20cm
▪ NFC is based on Radio Frequency Identification (RFID)
standards
▪ NFC Specifications:
Trang 202.2.3 Near field communication (NFC):
• Active mode
• Passive mode
58
2.2.3 Near field communication (NFC):
NFC provides a range of benefits to consumers and businesses, much depends upon
the installation of NFC, but the main benefits are:
▪ Intuitive– NFC interactions require no more than a simple touch
▪ Versatile – NFC is ideally suited to the broadest range of industries,
environments, and uses
▪ Open and standards-based- The underlying layers of NFC technology follow
universally implemented standards
▪ Technology-enabling - NFC facilitates fast and simple setup of wireless
technologies, such as Bluetooth, Wi-Fi, etc
▪ Inherently secure- NFC transmissions are short range
▪ Interoperable– NFC works with existing contactless card technologies
▪ Security-ready- NFC has built-in capabilities to support secure applications
59
2.2.4 Selection criteria for RFID systems:
❑ Operating frequency:
➢ High frequency systems have a significantly higher range than low frequency
systems Better reading speed rate
➢ Absorbtion rate: Low frequency is better then high frequency
➢ Electromagnetic interference fields: High requency is better
❑ Range: The required range of an application is dependent upon several factors:
➢ The positional accuracy of the transponder for security reason (reader and
transponder);
➢ The minimum distance between several transponders in practical operation The
distance between the transponders must be such that only one transponder is ever
within the interrogation zone of the reader at a time;
➢ The speed of the transponder in the interrogation zone of the reader
❑ Security requirement: micro processor should be used

Several steps are involved in the implementation of a typical ERP Package These
are:
1 Identifying the needs for implementing an ERP Package.
2 Evaluating the “As is” situation of the business.
3 Deciding the “would be” situation for the business.
4 Reengineering the business process to achieve the desired results in the
existing processes
5 Evaluating the various available ERP packages to assess suitability.
6 Finalizing the most suitable ERP package for implementation.
7 Installing the required hardware and networks for the selected ERP package.
8 Finalizing the implementation consultants who will assist in implementation.
9 Implementing the ERP package.

2.5 Bar Code:
2.5.1 Barcode overview:
▪ A barcode is an optical machine-readable representation of data relating to the
object to which it is attached
▪ There are 2 main types of barcode used in many fields nowadays:
Trang 362.5.3 2D Barcode:
• 1D Barcode has some disadvantages To find the solution to this problem, 2D
Barcode was invented
106
2.5.3 2D Barcode:
• As with 1D codes there are lots of variations of 2D codes including QR Code,
Color Code, EZcode, Aztec code, Bullseye, MaxiCode, 3-DI, Shot Code and
Trang 372.5.3 2D Barcode:
• Storage capacity: The amount of data that can be stored in the QR Code symbol
depends on the data type, version, and error correction level The maximum
storage capacities, for instance, occur for 40-L symbols
109
Numeric only Max 7,089 characters (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
Alphanumeric Max 4,296 characters (0–9, A–Z [upper-case only], space, $, %, *, +, -, ,
/, :)
Binary/byte Max 2,953 characters (8-bit bytes) (23624 bits)
Kanji/Kana Max 1,817 characters
2.5.3 2D Barcode:
• Error correction: use the Reed–Solomon error correction algorithm with four
error correction levels They are:
110
Level L (Low) 7% of codewords can be restored
Level M (Medium) 15% of codewords can be restored
Level Q (Quartile) 25% of codewords can be restored
Level H (High) 30% of codewords can be restored
