A manager is applying the transportation model of linear programming to solve an
aggregate planning problem. Demand in period 1 is 100 units and in period 2 demand is
150 units. The manager has 125 hours of regular employment available for $10/hour
each period. In addition, 50 hours of overtime are available for $15/hour each period. If
holding costs are $2 per unit each period, how many hours of regular employment
should be used in period 1 (assume demand must be met in both periods 1 and 2 for the
lowest possible cost and that production is 1 unit per hour)?
A) 100
B) 125
C) 150
D) 50
E) none of the above

A firm has established a distribution network for the supply of a raw material critical to
its manufacturing. Currently there are two origins for this raw material, which must be
shipped to three manufacturing plants. The current network has the following
characteristics:
The firm has identified two potential sites for a third raw material source; these are
identified as Candidate A and Candidate B. From A, the costs to ship would be $9 to
Plant 1, $10 to Plant 2, and $12 to Plant 3. From B, these costs would be $11, $14, and
$8. The new source, wherever it is located, will have a capacity of 500 units. Solve with
the transportation method. Which site should be selected?
Outsourcing manufacturing is also known as __________.
A metal works fabricator is about to release a new model of his firm’s copper sculpture
and fountain. The operations manager estimates that this product is subject to a 90
percent learning rate on labor only€the material bill is not affected by experience. The
firm prices its work based on cost€the sum of materials plus 30 percent and labor plus
50 percent. (This allows the firm to practice a little “demand management” for its very
popular works.) The first item has already been finished; the material bill was $800 and
labor totaled 40 hours. The firm pays its metalworking artisans an average of $18 per
hour. What should be the asking price of the first unit? The second?
The efficiency of a factory is 75% and its utilization 50%. If effective capacity is 1000
find design capacity.
