A brief review of the enabling technologies l.jpg
A Brief Review of the Enabling Technologies

  • Innovations in Information Engineering

    • 70’s: Data Processing (“Flat Files”)

    • 80’s: Information Systems (IS) – Real-time Database; Decision Support Systems

    • 90’s: Information Technology (IT) – Computer + Communication + GUI; Client-Server; Internet

    • 00’s: “Agents”? - Multi-agent Systems (MAS)

Networked – Agents and Intelligent Software Agents Group (NISA)


A brief review of the enabling technologies5 l.jpg
A Brief Review of the Enabling Technologies

  • Manufacturing Technologies

    • 80’s: Computer-aided Manufacturing (CAM)

    • 90’s: Computer-integrated Manufacturing (CIM)

    • 00’s: “Agent-based” Intelligent Manufacturing (AIM?)

A brief review of the enabling technologies6 l.jpg
A Brief Review of the Enabling Technologies

  • Software Development Paradigms

    • 70’s: Structured Analysis

    • 80’s: Entity-relationship; Relational Database

    • 90’s: Object-orientation; Software Components

    • 00’s: Agents; Multi-agent Systems (MAS)?

      • “Broker-oriented”agents

      • “Subject-oriented” agents: much more general

Business needs and impetus l.jpg
Business Needs and Impetus

Competition in the marketplace and technology, etc., led to:

  • Globalization: Geographically Distributed

  • Complex Supply Chain (Value Chain):

    • Distributed among corporations

    • Distributed within a corporation

  • Short Product Life Cycle

  • Agile and Lean Manufacturing

Networked – Agents and Intelligent Software Agents Group (NISA)


Business needs and impetus8 l.jpg
Business Needs and Impetus

  • Agile and Lean Manufacturing to Support

    • Rapid market responsiveness: new product introduction and innovation

    • Supply Chain Management

    • Globalization

  • Features:

    • Strongly time-oriented

    • Widely distributed

    • Strongly diverse or heterogeneous: hardware, software, communication, security, engineering process, management, etc.

Requirements for agent based intelligent manufacturing l.jpg
Requirements for Agent-based Intelligent Manufacturing

The devil is in the details.

  • Accommodating Heterogeneous Environments

  • Efficient Interoperability

  • Open and Dynamic Structure

  • Integration of Planning, Operation and Control

  • Integration of Human with Software, Hardware and Systems

  • Inter-organizational Cooperation

Networked – Agents and Intelligent Software Agents Group (NISA)


Agent based intelligent manufacturing applications l.jpg
Agent-based Intelligent Manufacturing: Applications

  • Agents to recognize and coordinate among various machines or subsystems of heterogeneous environments, as opposed to hard-coding coordination in CIM. (Broker-oriented)

  • Modeling a manufacturing enterprise as interaction among semi-autonomous agents, each with a degree of control over local resources or with different information requirements. (“Subject”-oriented)

Networked – Agents and Intelligent Software Agents Group (NISA)


Agent based intelligent manufacturing applications11 l.jpg
Agent-based Intelligent Manufacturing: Applications

  • Integrated Factory Planning, Operation and Control, with both types of agents

  • Organizing the supply chain as a network of cooperating (“subject”-oriented) intelligent agents, equipped with (broker-oriented) agents to facilitate or enable the interaction and integration
