Using the Newsboy Model
1.Needless Markup (NM), a famous “high end” department store,
must decide on the quantity of a high-priced woman’s handbag to
procure in Spain for the coming Christmas season. The unit cost of
the handbag to the store is $28.50 and the handbag will sell for
$150.00. Any handbags not sold by the end of the season are
purchased by a liquidator for $10.00 each. In addition, the store
accountants estimate that there is a cost of $0.40 for each dollar
tied up in inventory, as this dollar invested elsewhere could have
yielded a gross profit. Assume that this cost is attached to unsold
bags only.
Answer the following questions:
- Due to the long distance and limited capacity, NM must place
the order 6 months in advance. A detailed analysis of past data
shows that if forecasting 6 month in advance, the number of bags
sold can be described by a normal distribution, with mean 150 and
standard deviation 60. What is the optimal number of bags to
purchase?
- What is the expected cost of mismatch under the optimal
purchase quantity? What is the optimal expected profit?
- Another supplier in the U.S. offers the same product but at a
higher price of $35 due to its higher production cost. For this
supplier, NM only needs to place the order 3 months in advance
which results in a much better forecast. Past data shows if
ordering 3 months in advance, the number of bags sold can be
described by a normal distribution, with mean 150 and standard
deviation 20. Which supplier should NM choose?
