True

Which of the following items would be considered resources in a restaurant?

Chefs

Constructing a Demand Table

Construct a table with the number of rows corresponding to the number of resources, and the number of columns corresponding to the number of flow unit types

Little's Law is very general, so it is not necessary that flow rate and flow time use the same time units.

False

Rework can increase the costs of an operation but has no impact on the capacity of the process

False

Specialization typically lead to a higher average labor utilization

False

The implied utilization can never be bigger than 100 percent

False

The resource with the largest total demand rate is the bottleneck

False

To find the bottleneck in a process with attrition loss, all we need to do is find the resource with the lowest capacity

False

Forty customers per 90 minutes is a(n) ______

Flow Rate

Which of the following questions would be asked in a process analysis of a college admissions office?

If inventory is measured in kilograms, then when applying Little's Law the flow rate can be measured in ______

Kilograms per second

A process has a yield of 50 percent. How many units are needed as inflow to create an outflow of 40 units per day?

80

Is the capacity of the bottleneck larger than, equal to, or smaller than the capacity of the process?

Equal to

A group of workers works really hard. In fact, they work so hard that one of them claims to have an average labor utilization of 120 percent. Is that possible?

No

From the perspective of process analysis, which of the following could be appropriate flow units for a hardware store?

Number of customers

Which of the following statements about takt time and cycle time is true?

Takt time only depends on demand, not capacity. Cycle time does depend on capacity

A nonbottleneck worker currently has an idle time of 20 seconds per unit. Because of the large demand, the company improves the process by adding more capacity to the bottleneck. How does this impact the idle time of the worker?

The idle time would decrease

You and three of your friends run a car wash for a fund-raiser. Between interior and exterior cleaning, you spend about 40 minutes per vehicle. You are so successful that the next day you invite four more friends to help. How does this impact the labor content?

What happens to the target manpower if the labor content is doubled?

The target manpower doubles

What is the relationship between the processing time at a resource and its capacity?

They are reciprocals of each other
