Question 1

_____ is the typical queueing system used by supermarkets.

Accepted Answer

Supermarkets typically use a single queue that feeds into multiple checkout counters (servers), allowing customers to be served by the next available cashier, which optimizes wait times and service efficiency.

Question 2

In one method of calculating utilization,_____ divided by Resources Available.

Accepted Answer

Utilization is calculated by dividing the Resources Used by the Resources Available.

Question 3

A(n)_____ is a waiting line.

Accepted Answer

A queue is a waiting line.

Question 4

An airline has one employee work the counter.A customer arrives on the average of once every 3 minutes,and it takes on average 2 minutes to process the transaction.What is the probability that the system is empty?

Accepted Answer

The answer of An airline has one employee work the...

Question 5

_____ time is the average time it takes to complete one cycle of a process.

Accepted Answer

Flow time is the average time it takes to complete one cycle of a process.

Question 6

Flow time depends not only on the actual time to perform the tasks required,but also on how many other entities are in the work-in-process stage.

Accepted Answer

Flow time is influenced by both the time taken to perform tasks and the number of entities in the work-in-process stage, as congestion can lead to delays.

Question 7

Which of the following describes the general process for identifying a bottleneck?

Accepted Answer

A bottleneck is identified by finding the work activity with the smallest throughput, as it limits the overall capacity of the process.

Question 8

Which of the following is an example of a bottleneck management principle?

Accepted Answer

The answer of Which of the following is an example...

Question 9

Total process output is at the throughput rate of the bottleneck.

Accepted Answer

The throughput rate of a process is determined by its bottleneck, as it is the slowest step and limits the overall output rate of the entire process.

Question 10

Which of the following is NOT part of a queueing system?

Accepted Answer

A map of processes and functions is not a component of a queueing system, which typically includes servers, queues, and customers.

Question 11

The process for applying for a work permit at the Manchester department of labor is as follows.First,the administrator fills out an application (5 minutes)and takes a picture (1 minute).Then,a clerk enters the information and processes the permit (5 minutes).There are two administrators and three clerks.If the number of licenses per hour for the administrators is 16 and the number of licenses per hour for the clerks is 20.57,what can you conclude?

Accepted Answer

The administrators are the bottleneck resources because they can only process 16 licenses per hour, which is less than the clerks' capacity of 20.57 licenses per hour.

Question 12

Which of the following is NOT true about simulation models?

Accepted Answer

Simulation models can provide detailed analysis, not just estimates, and are often used when analytical models are not feasible or too complex.

Question 13

What is the average time a bouquet stays in a florist shop if they sell 100 bouquets per day and they maintain an average inventory of 200 bouquets?

Accepted Answer

The average time a bouquet stays in the shop is calculated by dividing the average inventory by the sales per day: 200 bouquets / 100 bouquets per day = 2 days.

Question 14

The philosophy and principles of the TOC are valuable in understanding demand and capacity management.

Accepted Answer

The Theory of Constraints (TOC) focuses on identifying and managing bottlenecks, which is crucial for effective demand and capacity management in any system.

Question 15

When calculating utilization,the dimensions of the denominator must be greater than those of the numerator.

Accepted Answer

Utilization is typically calculated as the ratio of used resources to available resources, so the dimensions of the numerator and denominator should be compatible, not necessarily greater or lesser.

Question 16

In an analytical queueing model,service times measure _____.

Accepted Answer

Service times in a queueing model measure the rates at which services are completed.

Question 17

Which of the following best defines the Theory of Constraints?

Accepted Answer

The Theory of Constraints is a management philosophy that focuses on identifying and managing the bottleneck in a process to improve overall system performance and increase throughput.

Question 18

The imputed cost of waiting is the reasonable value that might reflect the potential loss of future revenue or customer dissatisfaction.

Accepted Answer

The imputed cost of waiting considers the potential negative impacts, such as lost revenue or customer dissatisfaction, that can arise from delays or waiting times.

Question 19

Little's Law uses short-term averages to explain relationships.

Accepted Answer

The answer of Little's Law uses short-term averages to explain...

Question 20

Simulation models are not well equipped to capture the dynamic behavior of queues over time.

Accepted Answer

Simulation models are specifically designed to capture and analyze the dynamic behavior of systems, including queues, over time by modeling the interactions and changes within the system.
