14. 12 The purchasing manager for the Atlantic Steel Company must determine a policy for
ordering coal to operate 12 converters. Each converter requires exactly 5 tons of coal per day
to operate, and the firm operates 360 days per year. The purchasing manager has determined
that the ordering cost is $80 per order and the cost of holding coal is 20% of the average dollar
value of inventory held. The purchasing manager has negotiated a contract to obtain the coal
for $12 per ton for the coming year.
a. Determine the optimal quantity of coal to receive in each order. (Ans: 1200 tons)
b. Determine the total inventory-related costs associated with the optimal ordering policy
(do not include the cost of the coal). (Ans: TC= $2880)
c. If 5 days of lead time are required to receive an order of coal, how much coal should be on
hand when an order is placed? (Ans= R=300 tons)

Problem 20-10 (Algo)
You are a newsvendor selling San Pedro Times every morning. Before you get to work, you go to the printer and buy the day's paper
for $0.30 a copy. You sell a copy of San Pedro Times for $1.10. Daily demand is distributed normally with mean = 265 and standard
deviation = 53. At the end of each morning, any leftover copies are worthless and they go to a recycle bin.
a. How many copies of San Pedro Times should you buy each morning? (Use Excel's NORMSINV() function to find the correct critical
value for the given a-level. Round your z-value to 2 decimal places and final answer to to 2 decimal places.)
Optimal order quantity
b. Based on a, what is the probability that you will run out of stock? (Round your answer to the nearest whole number.)

- Torrance Refinery produces approximately 23.1 Million barrels of gasoline per year. A California distributor sources its gasoline from the Torrance refinery. The annual demand for gasoline at the California distributor is 5.3 Million barrels. The cost of storing gasoline is approximately $29 per barrel (per year). The cost of placing an order to the Torrance refinery (including shipping) is $7300 per order. Orders will be received gradually instead of delivered all at once (hence EPQ).
