Functional Design, Modeling and Analysis of a Facility-Level CIM System.
MetadataShow full item record
There is a critical need for establishing CIM at the facility level, to complement the research done in manufacturing integration, which has concentrated so far on flexible manufacturing cells, robotics and other material handling devices. This paper identifies the application modules that clearly lend themselves to an integrated information flow in a controlled manner: Computer aided design and computer aided process planning consist the product and process design centers of the proposed system respectively. Manufacturing resource planning undertakes the management of production plans to satisfy the market demand. The functional design of the system is derived from expertise in manufacturing management. The modeling and analysis are now formalized with the use of generalized Petri- Nets. The implementation strategy recognizes the existence of application tools that must be retained and subjected to synergism. Hence, a database interoperability language is in its final development stage, to enable the construction of the knowledge-base that will control the system. Extensions of this work include the incorporation of a shop floor control-module, to interface with the factory level.
