Computer Integrated Manufacturing (CIM)

What is CIM? The integration of business, engineering, manufacturing and management information that spans company functions from marketing to product distribution. CIM is manufacturing supported by computers. It is the total integration of Computer Aided Design / Manufacturing and also other business operations and databases. (Wikipedia ®)

CIM Definition The integration of the total manufacturing enterprise through the use of integrated systems and data communications coupled with new managerial philosophies that improve organizational and personnel efficiency Computer and Automation Systems Association of the Society of manufacturing Engineers (CASA/SME)

Other Definitions “CIM is a unified network of computer systems controlling and/or providing information to the function of a manufacturing business in an integrated way”. (Thomas, 1986) “Computer integrated manufacture (CIM) refers to the integrated information processing requirements for the technical and operational tasks of an industrial enterprise”. (Scheer, 1986) “… CIM relates to the use of computers for integrating the flow of information to aid the overall control of a manufacturing unit. …”. (Parnaby et al., 1986) “CIM is a philosophy rather than a specific system or set of applications…” (Lung, 1988) “CIM is a strategy for winning in manufacturing…” (Dutton, 1986)

Saying about CIM CIM is the integration of all enterprise operations and activities around a common corporate data repository. It is the use of integrated systems and data communications coupled with new managerial philosophies. CIM is not a product that can be purchased and installed. It is a way of thinking and solving problems.

CIM Vision “CIM is concerned with the integration of commercial, financial, engineering and production systems to improve responsiveness, quality, cost and competitiveness”. (Luscombe, 1993) “The CIM vision is one of total business integration with no local, departmental systems, no data that is duplicated unnecessarily, and no barriers between different functions”. (Luscombe, 1993)

The CIM Wheel

Elements of a CIM system Manufacturing engineering CAD/CAM, CAPP, coding & classification, … Manufacturing planning & control MRPII, MRP, CRP, shop floor control, inventory control, … Manufacturing processes NC/CNC/DNC, FMS, robots, material handling systems, … Indirect elements Sales order processing (& marketing) Finance & accounting

The Role of Computer in Manufacturing The computer has had a substantial impact on almost all activities of a factory. Often, the introduction of the computer changed the organizational structure of a department and made necessary adoption of new management structures.

Communication Networks A communication network is the backbone of an enterprise integration. Networks help to unify a company by linking together all the computerized devices irrespective of their physical location. Through networks the whole enterprise can be integrated, including suppliers and customers. For example Sales and marketing can send customer requirements for new products to design engineering. A CAD generated bill of materials can then be transferred to “material requirements planning (MRP)” systems. Product design information can be transmitted to manufacturing for use in process planning.

Potential Benefits of CIM Improved customer service Improved quality Shorter time to market with new products Shorter flow time Shorter vendor lead time Reduced inventory levels Improved schedule performance Greater flexibility and responsiveness Improved competitiveness Lower total cost Shorter customer lead time Increase in manufacturing productivity Decrease in work-in process inventory

Results of implementing CIM Reduction of design costs by 15-30% Reduction of the in-shop time of a part by 30-60% Increase of productivity by 40-70% Better product quality, reduction of scrap 20-50%
