Final answer:
The facility layout using teams of workers for complex units of a product is known as a cellular layout, which organizes workers into specific clusters or cells, differing from an assembly line.
Step-by-step explanation:
The facility layout that uses teams of workers to complete more complex units of the final product is known as a cellular layout. This approach organizes workers into clusters or cells, and each cell is responsible for completing a specific set of tasks or a particular part of the product. This is different from the assembly line method depicted in Figure 1.4, which is characterized by a mechanized work environment and focuses on producing identical products.
