What production method does ABC use for standard concrete?

• A. Just-in-time production.
• B. Batch production on a per-order basis.
• C. Flow production.
• D. Job-shop manufacturing.

Answer: (C)

Standard concrete is produced in large, uniform quantities using a continuous, streamlined sequence of steps. This makes flow production the best fit: the process is organized like an assembly line, with batching, mixing, and delivery arranged to keep material moving steadily, yielding high throughput and consistent quality. The product is homogeneous and demand is steady, so a continuous flow minimizes downtime and maximizes efficiency.

Just-in-time production aims to minimize inventory and tightly synchronize output with demand, which isn’t as suitable for a plant producing large volumes of a standard, non-custom product. Producing on a per-order batch would introduce unnecessary setup time and variability, reducing efficiency for a uniform material. Job-shop manufacturing is designed for customized, low-volume, high-variability products with flexible routing, which doesn’t fit standard concrete.
