Production systems: A product (line/flow) layout is most appropriate for which production type?

Introduction / Context:
Facility layout decisions match the physical arrangement of resources with the production strategy. Product layout aligns machines in the sequence of operations and is the foundation of assembly lines and continuous processes.

Given Data / Assumptions:

• High, stable demand for a standardized product.
• Well-defined, repetitive sequence of operations.
• Desire to minimize material handling and lead time.

Concept / Approach:
Product (line) layout suits mass production where each unit follows the same route. This enables line balancing, reduced WIP, shorter throughput time, and simpler scheduling compared with functional (process) layout used for job or batch work.

Step-by-Step Solution:

Verification / Alternative check:
Value-stream mapping and takt-time analysis typically show best performance for high-volume flows in a line arrangement.

Why Other Options Are Wrong:
Job/batch settings face varied routings and setups, favoring process/cellular layouts. “Any of the above” is incorrect because suitability is not equal across strategies.

Common Pitfalls:
Forcing a product layout onto highly variable, low-volume work; ignoring changeover times that can disrupt line balance.

Final Answer:
Mass production (high volume, standardized flow)
