TITLE = {ProCAD - A Produkt Modeling System for Power Plant System Design
},
ABSTRACTURL = {/publications/cgi-bin/tr-fetch.pl?r-96-36+abstr},
ABSTRACT = {ProCAD is a product modeling system for power plant system design. It is used for functional design of steam turbine, gas turbine, combined cycle, and pressurised fluid bed coal combustion (PFBC) power plants. 
The product models can contain descriptions of thousands of functional components: turbines, electrical generators, pipes, pumps, instruments, valves, heat exchangers etc. The power plant system designer can interact with the detailed information in the product model database directly from the drawing environment in the CAD-system. Reports and product documentation is generated from the product model database using 4GL applications with an SQL-interface.
The paper describes the system design of ProCAD. An overview of the structure of the product model database is given, and the CAD-client application for drawing process and instrumentation diagrams.
The paper provides examples of important generic functionality for multi user product modeling systems, such as configurable project specific attributes in the product model database, assignment of update access rights on distinct substructures in the product model to different engineers, and functions for checking the consistency between file based CAD-drawings and information in the product model database.
