Answer:
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 1,200 per hour.
You estimate the safety stock should be set at 5% 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
Answer:
Assume there are five jobs (i.e., A, B, C, D and E) that need to be sequenced in a

3 days (i.e., job A will take 3 more days to complete), B will take 9 days, C will take 6
days, D will take 5 days and E will take 8 days. In what order will these jobs be
scheduled if using the SOT priority rule for job sequencing?
A.A-B-D-E-C
B.A-D-C-E-B
C.D-C-A-B-E
D.B-E-C-D-A
E.E-D-A-B-C
Answer:
