What defines a Flexible Manufacturing System?

A Flexible Manufacturing System (FMS) is characterized by its ability to produce a variety of products using a combination of computerized machines and automated systems. Option B accurately describes this by emphasizing groups of CNC (Computer Numerical Control) machine tools that are integrated with automated material handling and control systems. This integration allows the system to adapt to changes in the type and quantity of products being manufactured.

The benefit of an FMS lies in its flexibility and efficiency; it can quickly switch from one product to another without significant downtime or reconfiguration. This is crucial in environments where product demand can fluctuate, enabling manufacturers to meet diverse customer needs while optimizing production processes.

In contrast, the other options highlight characteristics that do not align with the fundamental concept of flexible manufacturing. A combination of manual labor and CNC machining does not capture the essence of flexibility as it relies heavily on human intervention. A single machine designed for a specific task lacks the versatility associated with an FMS. Finally, a process that only involves human operators misses the technological integration that defines a flexible manufacturing environment.
