There are four hotels competing with otherwise very similar products on the dimensions of price ($ per night) and amenities (measured by the number of *s awarded by customer reviews).
Which of these hotels are on the efficient frontier?
A $200 3star
B $250 4star
C $300 5star
D $80 2star - ANSWER The only hotel that is Pareto dominated is hotel A - all other are on the efficient frontier. Hotel A is Pareto dominated by hotel B, as B is both cheaper and better.

From the perspective of process analysis, which of the following could be appropriate flow units for a hardware store?
day? Assume that the park is opened 365 days in a year. - ANSWER Flow rate = 3,200,000 visitors/365 days = 8,767.1233 visitors/dayFlow time = 20 hours / 24 hours/day = 0.8333 daysInventory = 8,767.1233 × 0.8333 = 7,306 visitors per day

Which of the following questions would be asked in a process analysis of a college admissions office?
A large bakery is designing a new production process for its packaged bread, which it supplies to a number of grocery chains. The baking of the bread takes 15 minutes.
How big must an oven be so that this firm can make 4000 units of bread per hour, assuming a production rate defined as the number of units baked at one time? - ANSWER 4,000 units / (15 minutes / 60 minutes) = 1,000 units
Which of the following is true about takt time and cycle time?
product, and that all activities are always done in the following sequence.
Resource 1 has a processing time of 7 minutes per unit.
Resource 2 has a processing time of 4 minutes per unit.
Resource 3 has a processing time of 6 minutes per unit.
All three resources are staffed by one worker and each worker gets paid $13 per hour.
What is the average labor utilization? - ANSWER Labor Utilization = 17 labor content/ capacity = 80.95%
Consider a process consisting of three resources. Assume there exists unlimited demand for the product, and that all activities are always performed in the following sequence.
Resource 1 has a processing time of 7 minutes per unit.
Resource 2 has a processing time of 4 minutes per unit.
Resource 3 has a processing time of 6 minutes per unit.
All three resources have one worker and each worker is paid $13 hourly.
Assume the demand rate is 20 units/hour. What is the takt time? - ANSWER Takt Time = 1/Demand rate = 1/(20 customers/60 minutes) = 3.00 minutes
Consider a process containing three resources. Assume that there is unlimited demand for the product and that the activities are always performed in the following sequence.
Resource 1 requires 7 minutes to process one unit. Resource 2 requires 4 minutes to process a unit. Resource 3 requires 6 minutes for the processing of one unit.
All three resources are supported by one worker, with each worker being paid $13 an hour.
Assume that demand rate is 20 units/hour. What is the target manpower? - ANSWER Target manpower = 17 Labor content/3.00 minutes Takt time = 5.
Consider a process comprising three resources. Suppose there is infinite demand for the product and that the activities are always executed in the order listed below.
Resource 1 takes 7 minutes per unit to process.
Resource 2 takes 4 minutes to process one unit of a product.
Resource 3 takes 6 minutes to process one unit of a product.
All three resources are manned by one worker, and each worker is paid $13 per hour.
If one more worker could be added, to which resource would the additional resources be allocated? Determine the process capacity. - SOLUTION Add the worker to resource
As the number of an attrition losses in a process increases, what happens to the yield?
Some of the resources have partial yields: 20 percent of material is discarded after the Acid step and 35 percent of the material is discarded after the separation step. The
Which of the following is most likely to be a concern if batches are very large?
A company is increasing the percentage value-added time in the operation. Its value-added time and its flow rate remain unchanged. What will happen to its inventory turns? (Recall from chapter 2 that inventory turns are computed as flow rate divided by inventory.)
If the percentage value add time is going up and their value add time remains constant, their flow time has to go down. And that means, holding flow rate constant, that the inventory turns have to go up (the inventory level goes down).
The information turnaround time is driven primarily by
Pulling the andon cord can lead to a loss of output. In TPS, an employee should pull the Andon cord
Which car company is most often associated with the term lean operations?

Within the Toyota Production System great importance is given to continually making things better. Which one of the following options would not be considered in typical approaches used within the Toyota Production System?
Which of the following statements about Pareto diagrams is correct?
According to Juran's quality cost framework, the cost of scrapping defective products found during production would be an example of: - ANSWER Internal Failure Costs
scrapping defective products in the factory means that the defects have been discovered in-house, so this is an example of internal failure costs
Which of the following statements is not true concerning customer complaints and service recovery?
Which of the basic quality tools below would be most useful for tracking the change in product defect rates over time? - ANSWER Run chart
Which of the following definitions describes a robust process?
You begin a summer job serving ice cream at the shore. The manager notices that since you started the job, the average portion size given to customers has gone up substantially. This is a result of assignable cause variation. - ANSWER True
Assignable cause variation is the variation that occurs because of a specific change in input or in environmental variables.
A tire company producing bikes would want their tires to have exactly a particular width for the cyclocross category. Suppose it wants them to be within a range of 22.8 mm to 23.4 mm. Also assume standard deviation is 0.19 mm and the average is 23.1 mm.
What would the Cp index for this process be? - ANSWER.
no more than.001 defect probability means that the probability in each tail must be no more than.
finding the probability of.005 in the standard normal table, we find Z = -3.
now, use the Z formula to solve for σ: -3.29 = (22.8 - 23)/σ → -3.29σ = -0.2 → σ =.
You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with US-Scareways. You know that in 21 percent of the cases the company has canceled the flight you were on. Should such a thing occur, there would be no other air travel option home for you. As a backup, your friend Walter has offered you a ride back. However, you know that Walter only has a seat in his car for you with 72 percent probability.
What's the likelihood that you will make it home for the holidays? ANSWER There are two variables each with two outcomes so we have 2 × 2 = 4 possible scenarios. For you not to make it home two things have to go wrong (a) the airline has to cancel the flight - 21% and (b) Walter's car is full - 28%.
Thus, you will not make it home with a probability of 0.28 × 0.21 = 0.0588. You will make it home with a probability of 0.9412.
You work for a small, student-run company that sends out merchandise with university branding to alumni worldwide.

What is the upper control limit for a p-chart?
SD = using p hat formula
UCL = P⎯⎯⎯ + 3 × Estimated standard deviation = 0.05 + 3 × 0.03082207 = 0.
For 40 days in the summer you work for a small student-run company that sends university-branded merchandise to alumni around the world.
