ISO TC 184 SC5 WG1 (Working Group 1)
Modeling and Architecture

Overview of Organization and Activities

TC184 Industrial Automation Systems and Integration

Scope: Standardization in the field of industrial-automation systems and integration concerning discrete-part manufacturing and encompassing the application of multiple technologies; that is, information systems, machines and equipment, and telecommunications.

(Exception: Electrical and electronic equipment as dealt with by IEC technical committees. Please refer to the IEC TC 44, TC 63, TC 3, TC 93 as examples where coordination occurs between IEC and ISO.

TC184 SC5: Architecture, Communications, and Integration Frameworks

Scope: Standardization in the field of enterprise architecture, communications, and processes to enable manufacturing system integration, interworking, and interoperability. This standardization will include:

• Process representations; such as exchange/negotiation in manufacturing enterprises
• Requirements for a global programming environment
• Manufacturing profiles likely to be utilized by industry

Chair: Emmanuel G. dela Hostria, US
Secretary: Greg Winchester, US

SC 5 P members, O members, and Liaisons

TC184 SC5 WG1: Modeling and Architecture

Scope: To develop a standard framework that coordinates existing, emerging, and future standards for the modeling of enterprises to facilitate computer-integrated manufacturing.

Current Activity: WG1 plans to produce standards that relate to information infrastructures, integration frameworks, enterprise models, enterprise reference architectures and methodologies, and manufacturing-process interoperability. ISO 14258, Concepts and rules for enterprise models, has been published as an International Standard (IS). ISO 15704, Requirements for enterprise reference architectures and methodologies, is being balloted as a Final Draft International Standard (FDIS). WG1 is planning a suite of standards to improve manufacturing process interoperability. For more information about WG1 plans for future standardization, see, under Resources in this World Wide Web site, TC184 SC5 WG1 New-projects description, Standards for the manufacturing enterprise, Process-interoperability improvements and Enterprise Representation: A Different Paradigm for Designing Process Interoperability Standards

WG1 feels that a standard within its scope should not mandate standard processes or standard enterprises. For more information about WG1 views regarding standardization in this domain, see, under Resources in this World Wide Web site, TC184 SC5 WG1 View on Standardization for Enterprise-Reference Architectures, Enterprise Models, and Process Interoperability.

WG1 meets from time to time, about three to four times a year. Since our work entails detailed review of various sections of the developing document to achieve a crafted consensus, WG1 has established some tools to facilitate the review process and minimize the number of meetings:

• There is an e-mail exploder to enable discussion and to distribute opinions and new draft material to interested people around the world. You may want to review the commands for using the exploder.
• The current WG1 work items are posted on this World-Wide Web site for a persistent reference.
• Activities of the WG1, such as agendas for upcoming meetings, past meeting minutes, and schedules, are also posted on this World-Wide Web site.
