Development Of A Message Model To Support Integrated Design And Manufacturing, Venkat Allada, Steven Ray Oct 1997

Development Of A Message Model To Support Integrated Design And Manufacturing, Venkat Allada, Steven Ray

Steven R Ray

Mere sharing of information between engineering design systems and manufacturing systems does not represent an ideal integrated system. While information sharing represents an important aspect of an integrated design and manufacturing environment, an equally critical aspect is the "interaction" capability of the two systems. This interaction could be in the form of feedback and request messages between the design and manufacturing systems. The goal of this study is to investigate the issues involved in the development of a conceptual message model that will facilitate an "upstream" and a "downstream" communication between the design activities and process planning activities. The development ...

Proceedings Of The First Process Specification Language (Psl) Roundtable, Craig Schlenoff, Amy Knutilla, Steven Ray

Steven R Ray

In April, 1997, the Process Speciļ¬cation Language (PSL) Project held a Roundtable discussion at the National Institute of Standards and Technology (NIST). The goals of the Roundtable was to assemble key champions and stakeholders of various approaches towards process representation in order to discuss the relative merits to reach consensus on a language architecture and to establish a technical approach for proceeding. It was agreed that the language architecture should be based upon a formal semantic foundation, upon which would be layered a number of syntactic mappings, each with one or more presentations.

In discussions about principal concepts of any ...
