2. Introduction
Successful application of agents must satisfy two perspectives
the researcher : demonstrate usefulness
the practitioner : cost-effectiveness
Agent applications in manufacturing and physical control

3. Contents 2. Why Use DAI in Industry?
3. Overview of the Industrial Life-Cycle
4. Where in the Life Cycle Are Agents Used?
5. How Does Industry Constrain the Life Cycle of an Agent-Based System?
6. Development Tools
7. Conclusions

4. Why Use DAI in Industry? Modular Decentralized Changeable
Ill-structured
Complex

5. Overview of the Industrial Life-Cycle
Requirements Definition
Specification
Design
Implementation
Commissioning
Decommissioning

6. Useful questions in comparing different agent applications
Individual agent
what in a system becomes an agent?
how does each agent model the world?
how are agents structured internally?

7. Cont’d Community of agent how many agents are there?
what communication channels do agents use?
what communication protocol do agents use?
how is the configuration of agents relative to one another established?
How do agents coordinate their actions?

8. Cont’d maturity of the application ( 6 levels ) 1. Modeled 2. Emulated
3. Prototype
4. Pilot
5. Production
6. Product

9. Where in the Life Cycle Are Agents Used?
in Product design
RAPPID
in Planning and Scheduling
AARIA
Daewoo
in Real-time control
Zone Logic

10. RAPPID
Designers and design variables are agent

11. Cont’d Technology used : set-based reasoning
market protocols among designers

12. AARIA
Resources, part types, unit processes, and engagements between a unit process and its resources are agents

13. Zone Logic
Complicated parts manufactured on a machine called transfer line
in traditional environment, the productivity is at most 50%
Zone Logic-controlled machine can achieve 90% productivity
Zone Logic makes each mechanism in the transfer line an agent

14. Constraints on the Life Cycle of an Agent-Based System
Requirement, Positioning, and Specification
Design
conceptual analysis
role-playing
formal analysis

15. Cont’d System implementation hardware standards
Z-world’s C-based offerings
LonWorks
Flavors PIM
standards
NIIIP, FIPA
DeviceNet

16. Development Tool as A single reactive process : IBM’s ABE
as Capitalists : Algorics’s Joule
as Travelers : IBM’s Aglets
as Members of community : Gensym’s ADE, Metra’s UNITY_Agent
as Intelligent Processes : dMARS, d-MUSE, ABS

17. Conclusions
The Systems must be practical, and the tools used to develop them must be packaged
For engineers in industry, agent technology is a means to an end, tool.
The big open issue in Application of DAI is the instantiation of the techniques that develop in standards
