Question

Computer Integrated Manufacturing (CIM) primarily refers to

• A. Using computers only in design
• B. Integration of manufacturing activities through computer systems
• C. Manual control of manufacturing operations
• D. Replacement of machines by computers

Hint:

Focus on the word "Integrated" in the term CIM.
This term implies a complete connection and synchronization of design, planning, and manufacturing tasks under a unified computer network.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the primary definition of Computer Integrated Manufacturing (CIM).

Step 2: Key Formula or Approach: This is a conceptual manufacturing systems question. CIM is a holistic manufacturing philosophy that integrates all production activities and business functions through computer-controlled databases and networks.

Step 3: Detailed Explanation:

• Computer Integrated Manufacturing (CIM) represents an automated approach where all aspects of the manufacturing enterprise are linked together.

• These aspects include product design (CAD), engineering analysis (CAE), manufacturing planning (CAM), quality control, and business functions like cost accounting and inventory management.

• Unlike CAD, which focuses only on product design (Option A), CIM integrates the entire workflow from raw materials to final delivery.

• CIM aims to optimize information sharing, improve production efficiency, and reduce lead times.

• Option C is incorrect because CIM emphasizes automation over manual control.

• Option D is incorrect because computers are used to control and coordinate machines rather than physically replace them.

Step 4: Final Answer:
CIM primarily refers to the integration of manufacturing activities through computer systems.
