Research Purposes
Order-Tracing Agent
• Corporate executives have difficulty in
make organizational enterprise
changes for extended integration
• Large amount and disorganized
information impedes enterprises
efficiency
• Quick response of order status
enables better customer services
What’s Intelligent Agent?
[Wooldridge and Jennings 1995]
• Autonomous: agents perform majority of their tasks
without the direct intervention of humans or other agents.
• Social ability: agents interact, when they deem order to
accomplish their tasks and to help others.
• Responsiveness: agents perceive their environment and
respond in a timely fashion to changes occurring in the
environment.
Classification of Agent
• Static and Mobile Agents
• Interface Agents
• Collaborative Agents and Multi-Agent

Advantages of Using Mobile Agent
• Cut down network load (makes the connection
quality better).

Mobile Agents and Network Load Reduction
(Danny B. Lange, 1998)
Advantages of Using Mobile Agent
(cont.)
• They overcome network latency
• They execute asynchronously and
autonomously. Mobile Agent has capability
of adapting and reacting network
environment changes dynamically and
automatically.
Advantages of Using Mobile Agent
(cont.)
• Fault-tolerant. When a host where Agent is
running tends to crash, all Agents will be
warned and given time to dispatch and
continue their tasks on another host in the
network.
• Scalability. Another benefit of using Agent
system is easy to add new Agents to an
existed Agent host.

User
When making a tracking request via a portal web-site,
users provide Order-No or Customer-No to User
Interface.
User Interface
User Interface receives users’ information and passes it
Coordinators.
Coordinators Agent
Coordinator Agent gets information from user through
User Interface, and then performs routing, that is,
figuring the company holding the user’s order.
Information Grabber
After routing, Coordinator Agent passes the information
got from user to Information Grabber. Then
Information Grabber grabs related data from external
source either via mid-tier programs or by itself.
External Resources
External Resource is where the needed data externally
stored.

Otherwise, Send Negative Message to the
Coordinators.
System
Procedure(1)
Order-Tracing Agent
Retailer
• 1. Send Customer ID or Order ID to retailer’s
website. Retailer means who the customer placed
order to. Any type of Web-Server can be used for
receiving users’ Order-Tracing request entrance
only if it is connected to Agent-Center.
• 2. Pass ID to Agent-Center. Alliances’ web-servers
must have two main features to work with AgentCenter. One is the parameters that will be received
by Agent-Center; two is the ‘action’ got to be
pointed to the Agent-Center’s address.
• 3. In the Agent-Center, here is a critical component
called Agent-Web-Server, which is full time
standby for receiving ID messages that customers
passed to retailer’s Web-Server. Agent-WebServer acts as the main role in the Order-Tracing
system. In this step, when retailer’s web-server
receives customers ID messages, it will be
automatically passed to Agent-Web-Server, and a
sequence of activities will be invoked by the AgentWeb-Sever.
System
Procedure(2)
Order-Tracing Agent
• 4 AgentCenterHub Agent is invoked to
decide which alliance it should dispatch
to. The searching mechanism is
designed and programmed here. By
retrieving the IP address stored in the
AgentCenter’s database, Agents have
AgentWebServer
specific destinations to go and ask for
certain services.
AgentCenterHub
• 5. After AgentCenterHub has destination
data in hand, Coordinators are invoked to
Coordinator
be dispatched to those destinations and
are given the customer’s ID data.
• 6. Coordinators invoke Information
Grabbers in Alliances’ hosts and pass the
ID to it.
System
Procedure(3)
Order-Tracing Agent
• 7. The Information Grabber invoked by
the Coordinator then starts to retrieve
the local database and set about its
order existence check procedure
according to the customer’s ID.
• 8. If this specific order is confirmed to
be existed in certain firm, the
Information Grabber then replies
‘Affirmative’ to the Coordinator. The
Coordinator then goes back and
reports it to the AgentWebServer Agent
to have the Presenter ready to present
the order information.

System Installation
Agent platform installation:
1. Directly copy the Aglet1.1_ from the source CD to the destination directory.
2. Set up the environment variable:
CLASSPATH:
Agent variable: .;C:\aglets1.1.0\lib;C:\aglets1.1.0\public;
For connecting Oracle database: o:\oracle\ora81\jdbc\lib\classes12.zip;
For connecting SQL database: C:\driver\freetds_jdbc\freetds_jdbc.jar
Add aglet_home variable and set it for your aglet directory
Add jdk_home variable and set it for your jdk directory
PATH:
C:\aglet1.1_\aglets1.1.0\bin;
Note that the C: or o: directory is depending on where you installed it for.
System Installation
Dealer side: copy the files from the CD’s directory “system/dealer_side” to your system’s (aglethome, usually named
Aglet1.1_)/ aglets1.1.0/ public/ thesis.
Data side: copy the files from the CD’s directory “system/data_side” to your system’s (aglethome, usually named
Aglet1.1_)/ aglets1.1.0/ public/ thesis.
Note: customize the “InfoGrabber.java” file for connecting the database. And then recompile this modified file and
reboot the Aglet system.
