Which of the following layouts has the highest flexibility?

Explanation:

Cellular Layout:

• It is a type of layout where machines are grouped according to the process requirements for a set of similar items (part families) that require similar processing. These groups are called cells. 
• Processes are grouped into cells using a technique known as group technology (GT).
• Group technology involves identifying parts with similar design characteristics (size, shape, and function) and similar process characteristics (type of processing required, available machinery that performs this type of process, and processing sequence).

Some of the advantages of cellular manufacturing include:

• Cost: Cellular manufacturing provides for faster processing time, less material handling, less work-in-process inventory, and reduced setup time, all of which reduce costs.
• Flexibility: Cellular manufacturing allows for the production of small batches, which provides some degree of increased flexibility.
