Equation 20.11 is for a fixed-time-period system with safety stock. It requires
An activity-system map is which of the following?

Assume there are five jobs (i.e., A, B, C, D, and E) that need to be sequenced in a
production schedule. The remaining operating time necessary for completion of job A is
4 days (i.e., job A will take 4 more days to complete), B will take 7 days, C will take 8
days, D will take 2 days, and E will take 5 days. Which job should be scheduled first if
you use the SOT priority rule for job sequencing?

B. B
C. C
D. D
E. E
In conducting aggregate operations planning, there are a number of required inputs.
Which of the following inputs are considered external to the firm?
A. Competitor behavior and economic conditions
B. Market demand and inventory levels
C. Subcontractor capacity and current workforce
D. Economic conditions and current physical capacity
E. Raw material availability and inventory levels
A company has recorded the last five days of daily demand on its only product. Those
values are 120, 125, 124, 128, and 133. The time from when an order is placed to when
it arrives at the company from its vendor is 5 days. Assuming the basic
fixed-order-quantity inventory model fits this situation and no safety stock is needed,
which of the following is the reorder point (R)?A. 120
B. 126
C. 630
D. 950
E. 1,200
Using Equation 20.4, Average demand is 120 + 125 + 124 + 128 + 133/5 = 126. Lead
time = 5 days, so the reorder point is 126 x 5 = 630.
In monitoring process quality, we might use which of the following statistics?
A. Absolute values
B. Percentage deviation from tolerance centers
C. “k” values for the sample mean
D. Logarithmic control intervals

Which of the following forecasting methodologies is considered a qualitative
forecasting technique?

E. Multiple regression
You have been called in as a consultant to set up a kanban control system. The first
thing you 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 1,200
per hour. You estimate the safety stock should be set at 5 percent of the demand during
lead time. The tote trays used as containers can hold 2 units of stock, and the lead time
to replenish an order is 10 hours. Which of the following is the number of kanban card
sets necessary to support this situation?
A. 5,000
B. 5,500
C. 6,300
D. 6,500
E. 7,000

E. Develop the sourcing strategy.
