2 Definition of CIM by the Computer and Automation Systems Association of the Society of manufacturing Engineers (CASA/SME): CIM is 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. 2 Al- Ameen Engg. College 2

3 What is 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. 3 Al- Ameen Engg. College 3

4 What is CIM? CIM is not a product that can be purchased and installed. It is a way of thinking and solving problems. 4 Al- Ameen Engg. College 4

5 CIM Objectives Simplify production processes, product designs, and factory organization as a vital foundation to automation and integration Automate production processes and the business functions that support them with computers, machines, and robots Integrate all production and support processes using computer networks, cross-functional business software, and other information technologies 5 Al- Ameen Engg. College 5

6 POTANTIAL 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 6 Al- Ameen Engg. College 6

7 CAPABILITIES OF CIM Responsiveness to rapid changes in market demand and product modification. Better use of materials, machinery and personnel. Better control of production and management of the total manufacturing operation. Manufacturing high quality product at low cost 7 Al- Ameen Engg. College 7

8 CASA/SME S CIM WHEEL By CASA/SME in 1980s 8 Al- Ameen Engg. College 8

9 Computer-Integrated Manufacturing Al- Ameen Engg. College 9

10 CIM Systems Computer-aided manufacturing (CAM) - automate the production process Manufacturing execution systems (MES) performance monitoring information systems for factory floor operations Process Control control ongoing physical processes Machine Control controls the actions of machines 10 Al- Ameen Engg.

11 LEAN MANUFACTURING Lean manufacturing is a philosophy that considers the expenditure of resources other than the direct creation of value for the end customer to be wasteful. Thus its targeted for elimination. Working from the perspective of the client who consumes a product or service. Al- Ameen Engg. College 11

12 Principles of Lean: 1. Eliminate Waste 2. Build Quality In 3. Create Knowledge 4. Defer Commitment 5. Deliver Fast 6. Optimize the Whole Al- Ameen Engg. College 12

13 AGILE MANUFACTURING Agile manufacturing is a term applied to an organization that has created the processes, tools, and training to enable it to respond quickly to customer needs and market changes while still controlling costs and quality. Agile manufacturing is seen as the next step after Lean manufacturing in the evolution of production methodology. Al- Ameen Engg. College 13

14 Principles of Agile: 1. Highest priority is customer satisfaction 2. Welcome changing requirements 3. Frequent delivery of software 4. Business people & developers cooperating daily 5. Build projects around motivated people 6. Face-to-face conversation is best 7. Progress measured by working software 8. Sustainable development pace 9. Continuous attention to technical excellence 10. Simplicity 11. Self-organizing teams 12. Regular reflection & adaptation Al- Ameen Engg. College 14

15 DIFFERENCE lean NO Customization agile Customisable Only 1 or 2 versions of product. Numerous options are available Al- Ameen Engg. College 15

16 Al- Ameen Engg. College 16

17 DIFFERENCE lean agile Minimum Inventory Inventory Buffers Perfect Quality Acceptable Quality Al- Ameen Engg. College 17

18 DIFFERENCE lean Focus on factory operations agile Scope is enterprise wide Al- Ameen Engg. College 18

19 DIFFERENCE lean Mass Production agile Mass Customization Emphasis on efficient use of resources Emphasis on continuous change Smooth production schedule Production schedule is responsive to change Al- Ameen Engg. College 19

20 SIMILARITIES Both ultimately focused on increasing business sustainability in the high-cost manufacturing sector. Both are answers to challenges faced by historical manufacturers. Both provide opportunities for smaller players to compete with larger, entrenched competitors Both concepts rely heavily on statistical analysis, computerized information systems and open communication between internal and external stakeholders.
