Rule-based Integration of Business Oriented and Technical Components in CIM Systems

Today many enterprises are forced to produce products which fulfill individual customer requirements. This situation results in an exploding number of variant parts of a product again resulting in a huge number of product data. To meet these new requirements, many enterprises introduced powerful CIM systems. Normally, this leaded to heterogeneous EDP concepts which are characterized by autonomous CIM components, each with its own database. This paper illustrates how rule-based management of product data on the one hand significantly reduces the amount of product data and how rule-based management of product data on the other hand allows to automate data exchange between several CIM components. One important consequence of this approach is, that the integration of business oriented and technical components within a CIM system is significantly improved.     

Strategies for planning and implementation of flexible fixturing systems in a computer integrated manufacturing environment

In general, for any manufacturing operation to be successful, parts must be located and held to remain in position and orientation when subjected to external forces during the manufacturing operations. The traditional approach to fixturing involves designing and manufacturing special-purpose fixtures. These fixtures are generally dedicated devices designed and manufactured for specific parts and manufacturing operations. Flexible fixturing technology involves employing a single fixturing system to hold workpieces of various shapes and sizes. Such systems have reached the embryonic stage of implementation into manufacturing environment. Therefore the integration of current and future flexible fixturing systems into the manufacturing processes becomes an important issue for future work in computer-integrated manufacturing (CIM) environment.

The approach to CIM is dependent on the functional model of the company. Therefore, the implementation of any sub-systems within it must be studied on an individual basis. However, in order to plan and implement new technologies, such as flexible fixturing systems, within CIM environment, certain requirements must be met and guidelines must be followed. The strategies for planning and implementation of flexible fixturing systems within the larger frame work of CIM environment are presented. Some guidelines for designing and developing the interconnection of the data bases are also discussed.     

The metadatabase approach to integrating and managing manufacturing information systems

Integration has become a self-evident goal in today's manufacturing enterprises. Since the late 1970s, numerous efforts have been launched world-wide to develop, employ, and deploy integration technology as a strategic weapon to compete in the global market-place. Important results have been obtained, including computer integrated manufacturing (CIM), concurrent engineering, and enterprise re-engineering. The field is poised to tackle some fundamental barriers of integration and thereby effect a new quantum jump in overall productivity, where information will become a fourth basic factor of production along with land, labor and capital. Among the barriers are the lack of information technology enabling multiple systems operating concurrently over different geographical regions. This paper discusses a unique approach to the integration problem regarding information resources management, global query and concurrent systems administration. This approach is based on the metadatabase model which incorporates both data and knowledge in order to accomplish information integration across manufacturing functions. Basic concepts, methods and techniques have been developed for the approach and verified via a prototype metadatabase system. The system's primary components and major functionalities are discussed and illustrated in detail through the use of an extended example of a pilot manufacturing system comprising order processing, process design and shop floor control. It will also provide the reader with a simulated system demonstration.A preliminary version of this paper was presented to the Third International Conference on Computer Integrated Manufacturing, May 1992.     

Extending IDEF1X to model fuzzy data

IDEF1X has provided a formal framework for consistent modeling of the data necessary for the integration of various functional areas in computer integrated manufacturing (CIM). The basic idea has been extensively applied in current manufacturing industry. Imprecise and uncertain information, however, is generally involved in many engineering activities. It is especially true for constructing intelligent manufacturing systems. This paper provides extensions to the IDEF1X, which makes it possible to represent fuzzy information.     

An information system for computer-integrated manufacturing systems

One of the main problems when implementing the computer-integrated manufacturing (CIM) concept concerns information integration. In order to support information integration, an information system provided with suitable data models is required. In this paper an information system is presented, which fulfils the requirements for an appropriate information management in CIM. For this purpose, an EXPRESS-oriented information system has been built on top of a commercial relational DBMS. The conceptual model of the information is built in EXPRESS and then parsed and translated to the corresponding relational constructs. A data access interface has been implemented which allows EXPRESS-oriented data manipulation. The information system was developed inside ESPRIT project No. 2202 CIM-PLATO “CIM System Planning Toolbox” to integrate the information used by the tools developed for flexible manufacturing system planning.     

A methodology for expressing CIM reference architectures

TNO is doing research in many areas of industrial automation and is heavily involved in European projects financed by R&D programmes such as Esprit, Eureka and Brite, and in many ISO and CEN standardization activities. From this experience it becomes clear that the I of Integration in CIM has not only to do with the integration of the so-called “islands of automation” but also with the integration of ”islands of manufacturing”: how we can improve the transfer of manufacturing knowledge. We have to increase the semantic content of our integration approaches, so that not only can computer scientist be involved, but also people from the companies we are trying to help, and people who are responsible for the development of new CIM components. The real problem is not a problem of technical integration of computers, but much more a “conceptual modelling” problem. Fundamental questions are, for instance, how we can, on the semantic level really required, model information transfer upstream and downstream in the product life cycle. Based on the analysis of existing CIM projects such as CAD*I, CIM- OSA, Open CAM Systems (Esprit I) IMPACT (Esprit II), CAM-I's CIM Architecture, the Danish Principal model for CIM, and more, we developed a generic and reusable CIM reference architecture. This architecture shows manufacturing activities, real and information flow objects, CIM components and industrial automation standards like STEP, MAP, TOP, EDIFACT, MMS etc. in an integrated way. In this paper we describe the CIM base model used to express the CIM reference architecture and give some details of the CIM reference architecture itself.

Current status and future trends of CIM in the Japanese steel industry

The growth of the Japanese steel industry has been supported by three factors: operation, equipment, and management technology. Computer-integrated manufacturing (CIM) is the core of management technology. CIM's purpose is to improve production efficiency through computer integration of data covering the staff (design and production control) and management department as well as the production line process department (order entry, manufacturing, and shipment). In this paper, an overview of the Japanese steel industry's system development process is given and the steps taken in order to establish the CIM system are described. The organization, operation, and improvement of operational capability, along with marketing and production-related systems, are integrated. Furthermore, an integrated system model is given as a CIM conceptual model. In closing, reference is also made to the challenges facing CIM in the Japanese steel industry as well as future directions to be taken.
