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.

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
