Chapter 5 Process Analysis with Multiple Flows
1) All flow units will have the same exit point in a production process.
Answer: FALSE
Explanation: 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
Topic: Generalized Process Flow Patterns
Learning Objective: 05-01 Compute the demand for a resource in the process of serving/producing a mix of customers/products.
Bloom’s: Remember
AACSB: Analytical Thinking

2) A bottleneck resource must have an implied utilization of less than 100%.
Answer: FALSE
Explanation: An implied utilization of less than 100% simply means that the resource has the capacity to meet demand. It has no bearing on whether or not the resource is a bottleneck.
Difficulty: 2 Medium
Topic: How to Find the Bottleneck in a Process with Multiple Flows
Learning Objective: 05-02 Compute implied utilization to find the bottleneck in a general process flow.

3) The overall process yield is the sum total of the yields of all resources.
Answer: FALSE
Explanation: The overall process yield is the product of the yields of all resources.
Difficulty: 1 Easy
Topic: Attrition Losses, Yields, and Scrap Rates
Learning Objective: 05-04 Compute the yield of a process and be able to analyze a process flow with yield loss.

4) When analyzing a process flow with flow-dependent processing times, the unit of analysis should be a unit of demand.
Answer: FALSE
Explanation: When analyzing a process flow with flow-dependent processing times, the unit of analysis for a flow unit becomes a time unit, such as a number of minutes or hours of work.
Difficulty: 2 Medium
Topic: Flow Unit–Dependent Processing Times
Learning Objective: 05-03 Analyze a process with flow-dependent processing times.

5) Rework always lowers the process capacity.
Answer: FALSE
Explanation: Rework lowers the processing capacity only when it involves a bottleneck resource in restoring reworked units.
Difficulty: 3 Hard
Topic: Rework
Learning Objective: 05-05 Analyze a process with rework.
Bloom’s: Analyze
