CIM - OSA .1. TOTAL ENTERPRISE MODELING AND FUNCTION VIEW

The objective of Computer-Integrated Manufacturing (CIM) is the appropriate integration of enterprise opernrions by means of efficient information exchange within the enterprise with the help of Information Technology (IT). Integl: alion includes the physical and logical connection of processes by means of data communications technology operating to specified standards, but also the integration of enterprise functions as well as enterprise information. Generalized models and an open systems architecture arc required to reduce the system complexity to a manageable level. They are used to identify the principal components, processes, constraints and information sources used to describe a manufacturing enterprise progressing towards Gl M: In this paper, the basic concepts of an opensystems architecture for CIM called CIM -OSA arc presented. The function view of the CIM -OSA modelling framework is discussed. eIM-OSA provides a unique set of advanced features to model functionality and behaviour of OfM systems at three distinct levels (requirements definition, design specificaI ion and implemcnration description). © 1990 Taylor & Francis Group, LLC.
