Question: After a careful analysis, managers at Haremon's have concluded that 20 customers per hour need
to check out. If the sole cashier can check out 25 customers per hour, what is the cashier's (implied)
utilization? 80% 125% 50% 20
Correct Answer: 80% ()
Question: Which of the following combinations does NOT have a utilization of 50%? The system makes
jet engines. Capacity = 240 / year; Demand = 10 per month The system is a restaurant. Capacity = 2 /
minute; Demand = 60 / hour The system is a Doctor's office. Capacity = 5 per minute; Demand = 600 /
hour. The system is a ride at Disney. Capacity = 1 / (6 minutes); Demand = 5 / hour
,Correct Answer: The system is a Doctor's office. Capacity = 5 per minute; Demand = 600 / hour.
Question: Hammon's is contemplating opening a little stand-alone satellite store. After a careful analysis,
managers have concluded that 25 customers per hour will need to check out at the satellite store (this will be
the long-run average demand at the store). They are considering hiring two cashiers, each of whom can
check out a customer in 5 minutes on average. What can you say about this system? This system will not
work perfectly smoothly but will function adequately (a customer may occasionally have to wait but not for
long). The system will work smoothly; leave it as is. This system will be unworkable since the implied
utilization is greater than 100%. The managers at Hammon's need to do something. This system is
workable; in fact they can do without the second cashier.
Correct Answer: This system will be unworkable since the implied utilization is greater than 100%. The
managers at Hammon's need to do something.
Question: Imagine a simple process in which 5 ticket booths are selling tickets for an opera. If customers

explanation). On average 20 customers arrive per hour who want a repeat prescription, and also 20 who
want a first-time prescription. How many employees should this pharmacy hire at the bare minimum? 3 4 1

payment. Per customer, step a) takes 2 minutes on average, step b) takes 3 minutes on average, step c) takes
1 minute on average, and step d) takes 4 minutes on average. By how much would the system capacity
increase if another person is hired for step b)? 50% 100% 25% 75%

Question: Wham-O makes 3 plastic toys; hula-hoops (product H), strawshooters (product S), and
wingdingers (product W). Wham-O has 4 resource types that are used in production - the process times
required to make each toy at each resource type (and the number of processors of each type) are shown in
the table below. For example, hula-hoops must go through Extrusion, Forming and Packaging (but
hula-hoops do not require any process time at the "Finishing" step). Each resource is operated 10 hours each
day. For example, in one hour, Extrusion can process 40 hula-hoops if it only works on hula-hoops (i.e., one
every 3 minutes, so 20 per hour, for each of the two processors), or it can process 30 strawshooters if it only
works on strawshooters, or it can process 60 wingdingers if it only works on wingdingers (alternately, it can
process some combination of H, S, and W). If demand is 100 units per day for hula-hoops, plus 100 units
per day for strawshooters, plus 120 units per day for wingdingers, then what is the utilization of Forming?

Question: A party of 5 goes to the Green Iguana. The waiter takes 10 seconds to get from the kitchen to the
table (or vice versa), and takes 30 seconds to manually take each person's order at the table. The waiter
always starts in the kitchen, goes out to a table, takes the order for the batch (whatever the batch size), and
then delivers the order for only that batch back to kitchen. If the waiter takes the table's orders in batches of
1 (only taking the order of 1 person), what is the waiter's total time required to process the job for the entire
table? 170 seconds 250 seconds 30 seconds 10 seconds

Question: A student has 3 total hours available for studying every night. An op's professor assigns her
students 10 op's questions every day. After the student "prepares himself" to work on operations, each
problem takes 6 minutes to complete. An accounting professor similarly assigns her students 10 questions
every day, each of which takes 6 minutes to complete after the student is "prepared" to work on accounting.
The student is "prepared" to immediately work on the next op's problem if he just completed an op's
problem, and similarly he is "prepared" to immediately work on an accounting problem if the student just
completed an accounting problem. Unless he just completed an op's problem, it takes the student 5 minutes
to get prepared before tackling an op's problem, and similarly, unless he just completed an accounting
problem it takes him 5 minutes to get prepared to tackle an accounting problem. What is the "pure process
time" associated with completing one homework problem? 6 minutes It depends on the lot size 11 minutes
5 minutes
Correct Answer: 6 minutes
Question: Continuing with the previous homework problem, what is the minimum amount of time the
student needs to study each night? 130 minutes 120 minutes 180 minutes The student cannot complete the
problems in the 180 minutes he has allotted
Correct Answer: 130 minutes
Question: Continuing with the previous "homework" question, the student proposes doing the problems in
batches of five, meaning completing five op's problems followed by five accounting problems followed by
five op's problems, followed by five accounting problems. What will be the student's implied utilization?
100% More than 100%
Correct Answer: The answer is the explanation or keyed response connected to this question in OSC 5100
- Final/Midterm Exam Guide. It identifies the relevant definition, function, procedure, or principle for this
topic.
Question: Continuing with the earlier "homework" question, the student proposes to break each professor's
daily assignment of 10 problems into 10 lots (the previous problem assumed 2 lots of 5, now the proposal is
10 lots of 1, meaning an op's problem followed by an accounting problem followed by an op's problem...).
What will be the student's implied utilization? More than 100% 100%
