What is the primary goal of lean production?

  1. To minimize waste and increase efficiency

  2. To maximize production output

  3. To reduce costs and increase profits

  4. To improve product quality


Correct Option: A
Explanation:

Lean production aims to eliminate waste and improve efficiency by focusing on continuous improvement, reducing defects, and optimizing processes.

Which of the following is NOT a principle of lean production?

  1. Eliminate waste

  2. Reduce defects

  3. Increase production output

  4. Optimize processes


Correct Option: C
Explanation:

Lean production focuses on eliminating waste and improving efficiency, not on increasing production output.

What is the term for the systematic identification and elimination of waste in lean production?

  1. Value stream mapping

  2. Kaizen

  3. 5S

  4. Total productive maintenance


Correct Option: A
Explanation:

Value stream mapping is a technique used in lean production to identify and eliminate waste in a process.

Which of the following is NOT a type of waste in lean production?

  1. Overproduction

  2. Waiting

  3. Transportation

  4. Value-added activities


Correct Option: D
Explanation:

Value-added activities are not considered waste in lean production, as they contribute to the value of the product.

What is the term for the continuous improvement process in lean production?

  1. Kaizen

  2. 5S

  3. Total productive maintenance

  4. Single-minute exchange of dies


Correct Option: A
Explanation:

Kaizen is the Japanese term for continuous improvement, which is a fundamental principle of lean production.

Which of the following is NOT a tool used in lean production to improve efficiency?

  1. 5S

  2. Kanban

  3. Total productive maintenance

  4. Statistical process control


Correct Option: D
Explanation:

Statistical process control is not typically used in lean production, as it is more focused on quality control than efficiency improvement.

What is the term for the visual management system used in lean production to organize and identify items?

  1. 5S

  2. Kanban

  3. Total productive maintenance

  4. Single-minute exchange of dies


Correct Option: A
Explanation:

5S is a visual management system used in lean production to organize and identify items, making them easier to find and use.

Which of the following is NOT a benefit of lean production?

  1. Reduced waste

  2. Increased efficiency

  3. Improved product quality

  4. Increased production costs


Correct Option: D
Explanation:

Lean production aims to reduce costs by eliminating waste and improving efficiency, not by increasing production costs.

What is the term for the production system that aims to minimize waste and maximize resource efficiency?

  1. Lean production

  2. Circular economy

  3. Cradle-to-cradle design

  4. Zero waste manufacturing


Correct Option: B
Explanation:

The circular economy is a production system that aims to minimize waste and maximize resource efficiency by reusing, recycling, and recovering materials.

Which of the following is NOT a principle of the circular economy?

  1. Design for reuse and recycling

  2. Use renewable energy sources

  3. Reduce waste and pollution

  4. Maximize production output


Correct Option: D
Explanation:

The circular economy focuses on minimizing waste and maximizing resource efficiency, not on maximizing production output.

What is the term for the process of recovering materials from waste and reusing them in new products?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling is the process of recovering materials from waste and reusing them in new products, reducing the need for raw materials and minimizing waste.

Which of the following is NOT a benefit of the circular economy?

  1. Reduced waste and pollution

  2. Increased resource efficiency

  3. Creation of new jobs

  4. Increased production costs


Correct Option: D
Explanation:

The circular economy aims to reduce costs by minimizing waste and maximizing resource efficiency, not by increasing production costs.

What is the term for the design approach that aims to minimize waste and maximize resource efficiency throughout a product's lifecycle?

  1. Cradle-to-cradle design

  2. Life cycle assessment

  3. Eco-design

  4. Sustainable design


Correct Option: A
Explanation:

Cradle-to-cradle design is a design approach that aims to minimize waste and maximize resource efficiency throughout a product's lifecycle, from raw material extraction to end-of-life disposal.

Which of the following is NOT a principle of cradle-to-cradle design?

  1. Eliminate waste and pollution

  2. Use renewable energy sources

  3. Design for reuse and recycling

  4. Maximize production output


Correct Option: D
Explanation:

Cradle-to-cradle design focuses on minimizing waste and maximizing resource efficiency, not on maximizing production output.

What is the term for the manufacturing approach that aims to eliminate waste and minimize environmental impact?

  1. Zero waste manufacturing

  2. Lean manufacturing

  3. Circular manufacturing

  4. Sustainable manufacturing


Correct Option: A
Explanation:

Zero waste manufacturing is a manufacturing approach that aims to eliminate waste and minimize environmental impact by reducing, reusing, and recycling materials.
