Final answer:
A job shop typically has a higher number of set-ups when compared to a flow shop. This is because job shops cater to custom orders, necessitating frequent changes in production setups, unlike flow shops which have a standardized and continuous flow of products.
Step-by-step explanation:
The true statement about a job shop in comparison to a flow shop is that job shops have higher number of set-ups. A job shop operates on a flexible system where production is based on individual orders or small batches of differing products, requiring frequent changes or set-ups in the production process. This contrasts with a flow shop where there is a continuous flow of products, often standardized, and the material movement is less flexible, but there is less need for changing or setting up equipment.
Workers in job shops, as opposed to the specialized and more repetitive tasks of flow shops, often have a wider range of skills to accommodate the various custom jobs that they handle. This is reflective of earlier times when skilled craftsmen performed varied tasks compared to assembly lines where work is more repetitive and specialized, leading to a less skilled but faster production.
