learning theory. The time required to do a task will vary randomly each
time the task is repeated. Unit time will decrease at an increasing rate.
Learning will not be transferred from one worker to the next. The
reduction in unit time will follow a predictable pattern. 11. A company's
production process has an 80 percent learning curve rate. The process
has produced 1,000 units to date. A process refinement is estimated to
allow a future learning curve rate for the identical product of 75 percent.
However, the initial unit made using the new process will take the same
amount of time as the initial unit produced using the old process. At
what point, using the new process, will the production rate exceed the
production rate achieved by the old process? Before the 100th unit
Before the 120th unit Before the 80th unit Before the 50th unit Before
the 250th unit 12. For which of the following should we use a p-chart to
monitor process quality? Grades in a freshman "pass/fail" course
Temperatures in a classroom The dimensions of brick entering a kiln
The weight of fluid in a container Lengths of boards cut in a mill 13.
You have been called in as a consultant to set up a Kanban control
system. The first thing to do is to determine the number of Kanban card
sets needed. Your research shows that the expected demand during lead
time for a particular component is 150 per hour. You estimate the safety
stock should be set at 25 percent of the demand during lead time. The
tote trays used as containers can hold 8 units of stock, and the lead time
it takes to replenish an order is 2 hours. Which of the following is the
number of Kanban card sets necessary to support this situation? 42 68 89
47 94 14. Which of the following is a fixed-time-period inventory
model? Just-in-time model The EOQ model Periodic system model The
Q model The least cost method 15. A company is planning for its
financing needs and uses the basic fixed-order-quantity inventory model.
Which of the following is the total cost (TC) of the inventory given an
annual demand of 10,000, setup cost of $32, a holding cost per unit per

3. year of $4, an EOQ of 400 units, and a cost per unit of inventory of
$150? None of these $1,501,600 $1,498,200 $499,313 $500,687 A.
$1,501,600 Q = 400. Average Inventory = Q/2 = 200. Holding
cost/year = $4. Thus, annual holding cost = $800. Annual set-up cost =
10,000/400 = 25 x $32 = 800. Demand x cost per unit = 10,000 x $150 =
1,500,000. Hence, TC = $1,500,000 + 800 + 800 = $1,501,600. 16.

is a "focusing step" of Dr. Eli Goldratt's theory of constraints? Identify
system constraints. Support system constraints. If you have no system
constraints, make some. Reduce system constraints. Reinforce system
constraints. 18. In designing a lean production facility layout, a designer
should do which of the following? Locate flexible workstations offline.

for the same three years are 120, 120, and 130. Which of the following is
the resulting MAD value that can be computed from these data? 3 1 15
123 5 C MAD = ABS[(124 - 120) + (126 - 120) + (135 - 130)]/3 = 15/3

5. 1. Identify a disadvantage of implementing group technology in a firm.
The number of employees required for a process increases
exponentially. The workers must be flexible enough to run several
machines and processes. It increases inventory. The waiting time
between operations is increased. 2. A shopkeeper purchases raw

Define synchronous manufacturing as stated by Goldratt's theory. It is a
production process organized to achieve the goals of the firm. It is an
integrated set of activities designed to achieve high quality and high
levels of production with minimal inventories of raw materials. It is a
production process in which machines are the critical resource used for
scheduling. It is the optimization of the rate at which cash is generated

company's strategy is delivered through a set of supporting activities. 17.
Define waste reduction. It is the process of combining the concept of
cross-docking and consolidation. It is the elimination of non—value-
adding activities and the optimization of value-adding activities that are
part of a process. It is the optimization of the rate at which cash is
generated by production through sales. It is the integration of activities
to increase the customer value of a process. 18. Identify the true

7. statements about the learning curve theory. It assumes that the unit time
for a task will decrease at a decreasing rate. A drawback of the learning
curve theory is that the performance can be measured only in terms of
time per unit. In a learning curve. the time for task completion will
increase each time the task is undertaken. In a learning curve the
reduction in time will be unpredictable. 19. is the characteristics of a

extensive interviewing of employees. It takes a longer time than general
management consulting to yield results that can be measured. 21.
Identify a true statement about water transportation mode. It is a highly
specialized mode of transport limited to the delivery of gases- Moving
high volumes of products is costly. It can handle a high capacity of
materials. Fast transit times can be achieved in this mode of
transportation. 22 A pharmaceutical company keeps detailed
