MANUFACTURING INFORMATION INTEGRATION IN PRODUCT LIFECYCLE MANAGEMENT (PLM)

摘要

The research on manufacturing information integration in PLM calls for a new fundamental information technology to enable adaptive information representation and exchange between manufacturing applications. Four major problems are studied, including interchangeable common data representation, management of information access, information reuse, and disturbance reflection of information change. An information model for manufacturing simulation is built. Problem about the abstraction of real models to virtual models is also discussed. A neutral model of shop information, developed by NIST based on the extensible Markup Language (XML), is detailed in this paper with illustrations from industrial applications.
