Final answer:
b. flexible manufacturing
The manufacturing system described, which is adaptive and uses computer-controlled technology, is classified as a flexible manufacturing system due to its ability to promptly change production types without significant downtime.
Step-by-step explanation:
The manufacturing system described by the student is known for its versatility and responsiveness to changes in production demands.
Because it leverages computer-controlled machining centers, robots, and remote-controlled carts, and because it can quickly adjust to manufacture various types of ball bearings, it is best characterized as a flexible manufacturing system.
This flexibility enables the production of multiple product types without the need for extensive retooling, thus aligning with the modern requirements of efficient and responsive manufacturing processes, much like how prefabricated building materials are created with precision and adaptability for urban development.
