unsold ornaments are destroyed at the end of the season, to
ensure the value of the limited edition.
a. How many boxes of each design should LGC manufacture?
b. What is the expected profit from this policy?
c. How many boxes does LGC expect to sell at a discount?
d. An option being considered by LGC is to separate choco-
late production from packaging. Chocolates will be pro-
duced before the start of the season, but packaging will be
done on an express line as orders come in. The express
line and separation of steps adds $2 to the cost of produc-
tion. How many boxes of chocolates should LGC manu-
facture if it decides to postpone packaging? What is the
expected profit? How many boxes will LGC sell at a dis-
count if it uses postponement?
e. At what additional cost of postponement (instead of the
current $2) would LGC be indifferent between operating
with and without postponement?
13. The Knitting Company (TKC) is planning production for its
four sweater styles that are popular during Christmas. All
four styles have demand that is normally distributed. The
best-selling style has an expected demand of 30,000 and a
standard deviation of 5,000. Each of the other three styles has
an expected demand of 10,000 with a standard deviation of
4,000. Currently, all sweaters are produced before the start of
the season. Production cost is $20 per sweater, and they are
sold for a wholesale price of $35. Any unsold sweaters at the
end of the season are discounted to $15, and they all sell at
that price. It costs $2 to hold the sweater in inventory for the

the expected profit?
b. The manufacturer has offered to discount the price to $28
per ornament if at least 25,000 are ordered. How should
the designer respond?
15. A publisher is printing calendars for the coming year.
Demand for calendars is normally distributed, with a mean of
70,000 and a standard deviation of 25,000. The cost per cal-
endar is $3, and they are sold for $10 cach. All unsold calen-
dars are recycled at the end of January.

What is the expected profit?

16. An electronics manufacturer has outsourced production of its
latest media players to a contract manufacturer in Asia.
Demand for the players has exceeded all expectations,
whereas the contract manufacturer has limited production
capacity. The electronics manufacturer sells three types of
players-a 40-GB player, a 20-GB player, and a 6-GB player.
For the upcoming holiday season, the demand forecast for
the 40-GB player is normally distributed, with a mean of
20,000 and a standard deviation of 7,000, the demand fore-
cast for the 20-GB player has a mean of 40,000 and a stan-
dard deviation of 11,000, and the demand forecast for the
6-GB player has a mean of 80,000 and a standard deviation
of 16,000. The 40-GB player has a sale price of $200, a pro-
duction cost of $100, and a salvage value of $80. The 20-GB
player has a sale price of $150, a production cost of $90, and
a salvage value of $70. The 6-GB player has a sale price of
$100, a production cost of $70, and a salvage value of $50.
a. How many units of each type of player should the
electronics manufacturer order if there are no capacity
entire season if it does not sell.
a. How many sweaters of each type should TKC manufacture?
b. What is the expected profit from this policy?
c. How many sweaters does TKC expect to sell at a discount?
d. TKC is considering the postponement of knitting and
using flexible machines. This will require the base sweat-
ers to be made in advance (identical for each of the four
types) and the final patterns to be knit later. This will
increase production cost per sweater to $21.40. How
many sweaters should TKC manufacture with postpone-
ment? What is the expected profit from this policy?
e. Another option is to produce the popular style without
postponement and the other three styles using postpone-
ment. What is the expected profit under this policy?

ornament. Demand has been forecast to be normally
constraints?
b. The contract manufacturer has available production
capacity of only 140,000 units. What is the expected
profit if the electronics manufacturer orders 20,000 units
of the 40-GB player, 40,000 units of the 20-GB player,
and 80,000 units of the 6-GB player?
c. How many units of each type of player should the elec-
tronics manufacturer order if the available capacity is
140,000? What is the expected profit?
