Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Define automation.

    Model answer

    Automation is the use of machinery and control systems to carry out a task with little or no direct human involvement.

  2. 2

    What is the difference between automation and robotics?

    Model answer

    Automation is any process run by machines rather than people, while robotics uses programmable machines that physically handle objects and can be reprogrammed for different tasks.

  3. 3

    How does automation affect unit costs as output rises?

    Model answer

    The equipment is a large fixed cost, so as output rises that cost is spread over more units and the cost per unit falls.

  4. 4

    State two benefits of using robots on an assembly line.

    Model answer

    Robots work continuously without breaks and repeat a task to the same tolerance every time, raising both output and consistency.

  5. 5

    Why can automation improve quality as well as output?

    Model answer

    A machine repeats the same movement to the same specification each time, so variation between units and the defect rate both fall.

  6. 6

    What are the two main drawbacks of automating a production process?

    Model answer

    The initial investment is very large, and the equipment is inflexible, so changing the product can mean costly reprogramming or replacement.
