Über dieses Buch

Computer Integrated Manufacturing (CIM) is the computerized handling of integrated operational processes between production planning and control, design, process planning, production, and quality assurance. The consistent application of information technology, along with modern manufacturing techniques and new organizational procedures, opens up great potential for rationalization by speeding up processes, thereby reducing stocks and improving product structure and delivery times. Following a comprehensive justification of the CIM integration principle, this book discusses the current state of applications and new demands arising from the integration principle as applied to the individual CIM components. The interfaces between business and technical information processing are considered in detail. The main emphasis, however, is on strategies for realization and implementation based on concrete experi- ence. The "Y-CIM information management" model, developed and tested at the author's institute, is presented as a procedural method for implementing CIM and demonstrated using up-to-date examples. In addition to the procedure for developing a CIM strategy, concrete sub-projects are developed which are directed at specific sector or enterprise structures. The survey of further CIM developments including design stage cost estimation, use of expert systems and inter-company process chains have proved to be effective CIM components since the first edition of this book and are now treated in the main text. Six German and five American industrial implementations are presented to illustrate the diverse areas of emphasis in the implementation sequence, and to indicate how CIM can be realized with currently available data processing tools.




In coming years the introduction of Computer Integrated Manufacturing (CIM) will become a matter of survival for many industrial concerns. Information technology will increasingly be recognized as a factor of production, not only influencing organizational structure, but also becoming a significant competitive factor.

A. The Meaning of the “I” in CIM

Computer Integrated Manufacturing (CIM) refers to the integrated information processing requirements for the technical and operational tasks of an industrial enterprise. The operational tasks can be referred to as the production planning and control system (PPC), as represented in the left fork of the Y in Fig. A.01. The more technical activities are characterized by the various CAX-concepts in the right fork of the Y. The PPC system is determined by order handling, whereas the CA-components support product description and the production resources. At the same time these information systems provide data for the associated financial and cost accounting systems.

B. The Components of CIM

The CIM components represented in the Y-diagram of Fig. A.01 are:
  • Production Planning and Control
  • Computer Aided Design
  • Computer Aided Planning
  • Computer Aided Manufacturing
  • Computer Aided Quality Assurance
  • Maintenance.

C. Implementation of CIM: Information Management

Establishing uniform process chains with their accompanying data flows and short term control possibilities gives rise to great rationalization potential. This explains the substantial user-acceptance of CIM principles. What can a user do, however, when CIM is widely discussed, but not (yet) available in the form of complete CIM systems?

D. CIM Implementations

Having developed a procedural approach to introducing CIM, several CIM implementations will be presented.

E. CIM Promotion Measures

The West German Minister for Research and Technology founded the promotion program “Production Technology 1988 – 1992” to promote the implementation of CIM solutions in West Germany. From this program industrial enterprises, primarily from mechanical engineering and plant engineering and construction, can obtain financial help in creating and implementing CIM systems. A further measure financed by this promotion program is the so-called “Expansion via CIM-Technology-Transfer”. Under this title the financing of the development of CIM-Technology-Transfer-Centers (CIM-TTC) at 16 higher education establishments in West Germany is provided (see Fig. E.I.01). The intention here is to provide, in addition to financial support, conceptual help to enterprises that want to examine CIM, in that the CIM know-how of the research institutes involved in the project is made generally available. The primary group at which the Technology-Transfer offer is directed are the small to medium sized operations, which possess desirable prerequisites for CIM implementation (e.g. considerable organizational flexibility, the use of standard software packages), but which lack the necessary specialist knowledge regarding the prospects and risks associated with CIM and procedures for CIM planning and introduction.
