Chapter 05 Test Bank KEY

1. All flow units should have the same exit point in a production process.

FALSE

Attrition loss is an example of when flow units exit the process before completion. Therefore, some flow units exit the process earlier than others.

Difficulty: 1 Easy

Gradable: automatic

Learning Objective: 05-01 Compute the demand for a resource in the presence of a product mix.

Topic: Generalized Process Flow Patterns

2. A bottleneck resource must have an implied utilization less than 100%.

FALSE

An implied utilization less than 100% simply means that the resource has capacity to meet demand. It has no bearing on whether or not the resource is a bottleneck.

3. The overall process yield is the sum total of the yields of all resources.

FALSE

The overall process yield is the product of the yields of all resources.

Learning Objective: 05-03 Compute the yield of a process and be able to analyze a process flow with yield loss.

Topic: Attrition Losses, Yields, and Scrap Rates

4. When analyzing a process flow with flow unit dependent processing times, the unit of analysis should be a unit of demand.

FALSE

The unit of analysis for a flow unit becomes a minute or hour of work instead of a unit of demand when analyzing a process flow with flow unit dependent processing times.

5. Rework always lowers the process capacity.

FALSE

Rework lowers the process capacity only when it involves a bottleneck resource in restoring reworked units.
