這個題目不會解～請教各位高手幫忙解～謝謝～
A retailer of computing products sells a variety of computer-related
products.One of her most popular products is an HP Laser Printer. The average
weekly demand is 200. Lead time for a new order from the manufacturer to
arrive is 1 week. If the demand for printers were constant, the retailer
woukd recorder when there were exactly 200 printers in inventory. However,
the demand is a random variable.
An analysis of previous weeks reveals that the weekly demand standard
deviation is 30. The retailer knows that if a customer wants to buy an HP
lawer Printer but she has none available, she will lose that sale plus
possibly additional sales.
QUESTION：Suppose selling a printer results in a profit of $2000.
However,keeping one more printer above 240 in stock costs $5. What is the
optimal inventory policy?
