138APPENDIX IIGLOSSARY OF THE PURDUE ARCHITECTURE ANDITS ASSOCIATED METHODOLOGY This Glossary was initially prepared by a Subcommittee of the Industry-Purdue University Consortium on An Implementation Procedures Manual for Developing Master Plans for Computer Integrated Manufacturing (CIM) 27 under the Chairmanship of Mr. Jim Brosvic of Honeywell, Inc. The Glossary was derived mainly from the following sources plus considerable input from the Consortium:1. The Honeywell Computer Automated Manufacturing (HCAM) Glossary, developed from Honeywells participation in the Consortium for Advanced Manufacturing International (CAMi). This Glossary was thoroughly revised by the Purdue Consortium Committee.2. The Information Flow Model of Generic Production Facility contributed by the Foxboro Company 118 to the work of the CIM Reference Model Committee of the International Purdue Workshop for Industrial Computer Systems 37. In view of the need for a Generic Enterprise Reference Architecture and Methodology (GERAM) based upon PERA, GRAI-GIM, and CIMOSA as proposed by Drs. Peter Bernus and Laszlo Nemes 101, 103 to the IFAC/IFIP Task Force on Architectures for Integrating Manufacturing Activities and Enterprises, a revision and expansion of this Glossary is necessary to clarify the differences in terminology as used by the major reference architectures. Concepts derived from recent development in PERA are also presented, such as those involved in interfaces, and in the tools provided by information technologies. In order to keep this Glossary to a reasonable length, some common words previously included have been removed. The following Glossary is organized alphabetically. Entries comprise a term in bold followed by one or more definitions of its principal meanings in the context of the Purdue Enterprise Reference Architecture and its associated Methodology. The part of speech of a term is specified in parentheses if it is not obvious from its everyday usage. The subject area of a definition is indicated in slanted style. The sources of a definition is noted in square brackets if the definition is an excerpt from sources other than the Purdue Enterprise Reference Architecture and its associated Methodology. Abbreviations used to indicate parts of speech and subject are as listed below.
