  1. An Agent-based Manufacturing Application Developed by NIST OMG Agent Working Group Meeting at Burlingame, CA September 11, 2000 Elizabeth Fong,ITL, NIST Nenad Ivezic, MEL, NIST Yun Peng, UMBC Tom Rhodes, ITL, NIST

  2. NIST Mission: • “ to assist industryin the development of technology ... needed to improve product quality, to modernize manufacturing processes, to ensure product reliability ... and to facilitate rapid commercialization ... of products based on new scientific discoveries.” • Working with Industry and Government to Develop and Apply Technology, Measurements, and Standards

  3. ICM Project Focus

  4. ICM Project Objectives • Demonstrate integration of EC services with technical data interchange. • Enable exchange of business and technical information for supply-chain participants. • Provide a flexible test-bed to collaborate in testing and evaluating standards-based tools and integration technologies.

  5. ICM Testbed • A collaborative environment for NIST and industry to integrate, test and evaluate IT technologies, specifications, and tools for manufacturing. • Develop and demonstrate prototype systems based on open standards. • Identify and integrate software tools for improving business and manufacturing process in e-commerce. • Test case implementation and conformance testing of standards.

  6. Testing Framework • Design goals: • Apply and evaluate use of agent technology • Apply and evaluate web-based technologies • Evaluate use of emerging standards, • (XML, RosettaNet PIP’s, OAG BOD’s, IPC • GenCam)

  7. Objectives for ICM Agent Work • Identify potential benefits of adopting an agent approach for improving B2B E-Commerce • Implement and evaluate the impact of agent technology for supporting complex EC applications with selected web-based PCA/PCB business processes, e.g., RFQ, Ordering, ECO, Introduction of New Products, etc. • Provide a software infrastructure for ICM testbed • Open and distributed • Scalable and extensible • Component-based

  8. Potential Areas for Agent Application in Manufacturing Services • Flexible Customer-to-Supplier Interfaces • Optimized Negotiation of Service Cost and Terms • Efficient Engineering Change Order (ECO) processing • Efficient Intra-Enterprise Technology Adoption and Adaptation • Efficient Inter-Enterprise Interaction Technology Support

  9. Some Agent Types • Interface Agents: Translation/Transformation Services • Human to application software • Software to software • Software to files, databases or web documents • Legacy system to another legacy system • Information Mgt Agents: Search & Retrieval Services - Searching and discovery - Information filtering • Brokering Agent: Smart Yellow Page Services - Interest matching • Negotiation Agent: Analysis Services

  10. RFQ Scenario in ICM Testbed • A B2B Multi-Agent System RFQ Scenario • RFQ issued from OEM to EMS over the Web • EMS asks for additional information • Technical information from GenCAM file will be accessed • Bid is shipped to OEM

  13. The GenCam Standard • GenCAM is a standard describing business and technical data for manufacturing PCA/PCB • GenCAM specification is produced by IPC • NIST built a conformance test for GenCAM • NIST is building boards and assemblies using GenCAM • GenCAM will express product description in XML

  14. ZOPE access methods Queries (XML) GenCam Specialist Agent GCOB Responses (XML) GenCam files Web Assistant Agent (GCA) Web Communication Component KQML Component XML Java Objects Web Server Sevlet1 Servlet2 Web Browser GenCam Specialist Agent (GCA)

  16. GCMAS Design Platforms and Tools • Platform: machine independent (windows 98/NT, Unix/Linux) • Languages: • Java (Sun Microsystem’s JDK1.2.2) for all agent code • Python-1.5.2 (for GenCam access methods) • XML (between GCA and GenCam Object Base) • Tcl/Tk , CLIPS (knowledge-base prototype) • XML/RDF (used to evaluate DAML) • Packages: • Jackal for agent communication (from IBM alphawork, developed by UMBC under the auspices of the CIIMPLEX project, a NIST ATP sponsored initiative • Access method for accessing the GenCam Object Base • Apache 1.3.12 (and JServ1.1) for EMS web server

  17. Expected Impact of Agent Solutions Save Steps - Automatically initiate actions - Eliminate human intervention Save Time - Provide product information on-demand - Support supply chain information integration Save Cost - Improve and optimize business processes - Offer an agent-framework for developing new applications (reuse)
