Element of a CIM system

CIM system

1. Manufacturing planning - RP, shop floor control, inventory control, …

2. Manufacturing engineering - CAD/CAM, CAPP, coding & classification, …

3. Manufacturing processes - NC/CNC/DNC, FMS, robots, material handling systems, …

4. Indirect elements: - sales order processing (& marketing) - finance & accounting

Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

What is CIM?

• The integration of business, engineering, manufacturing and management inform- mation that spans company functions from marketing to product distribution.

Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

• “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 theintegrated 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)

Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

• “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)

• “CIM is concerned with the integration of commercial,

financial, engineering and production systems to improve

responsiveness, quality, cost and competitiveness… 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)

Internal Challenges

- Analyse every product and agree on the order-qualifying and order winning criteria for the current market conditions for every product

- For every product, project the order winning criteria in the market in the future

- Determine the fit between the criteria necessary to succeed in the market place and the current capability in manufacturing

- Change or modify either the marketing goals or the manufacturing process choices.Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

Meeting the internal challenges

1. Set-up time

2. Quality

3. Manufacturing space ratio

4. Inventory

5. Flexibility

6. Distance

Stages of CIM development:

1. Computerisation of function

2. Islands of automation

3. Interfacing

4. Integration

Note: Advances in computing, information technology,database technology, communications, etc. have supported(or pushed) the development of CIM.

Lecturer: Dr. HABEEB ALANI University TENAGA Nasional

Some (claimed) benefits of CIM:

• Reduction in direct costs

• Reduction in engineering costs

• Reduction in manufacturing lead time

• Reduction in pre-production lead time

• Quicker response to market changes

• Reduced inventory

• Improved quality

• More effective management control of the business
