Information modeling for computerized manufacturing

An information modeling and design approach using a metadatabase framework and a two-stage entity-relationship (TSER) methodology to address the system integration problem is presented. The metadatabase framework is a simplification design entailing a federated system architecture, an integrated information model, and a knowledge-based control methodology. The TSER methodology, used for the information model, features both a semantic modeling construct encompassing the US Air Force's IDEF approach and an operational modeling construct for consolidating data structures across the manufacturing facility. Preliminary results of a pilot study, including both modeling and software system development, are included to illustrate the theoretical work. >
