	A company is about to begin production of a new product. The manager of the department that
	will produce one of the components for the product wants to know how often the machine used to produce
	the item will be available for other work. The machine will produce the item at a rate of 80 units
	a day. Fifty units will be used daily in assembling the final product. Assembly will take place five days
	a week, 50 weeks a year. The manager estimates that it will take almost a full day to get the machine
	ready for a production run, at a cost of $200.
	Inventory holding costs will be $10 per year.
REQUIRED:
a.	What run quantity (EPQ) should be used to minimize total annual costs?
b	What is the length of a production run in days?
c.	What is the cycle time?
d	What would the average inventory be for this lot size?
e	About how many runs per year would there be?

12-4	Given this information:
	Average weekly demand = 100 units.
	Standard deviation = 10 units.
	Lead time = 4 weeks.
	Acceptable stockout risk = 2.5%
	Ordering cost = $30
	Annual Holding cost = 20%
	Unit cost (purchase price) = $20
	The company operates = 50 weeks a year.
	Weekly usage rates are distributed normally.
	Determine each of the following, assuming that lead time demand is distributed normally:
	a. Order quantity (EOQ).
	b. The safety stock needed to attain a 2.5 percent risk of stockout during lead time.
	c. The reorder point (ROP) that will provide a risk of stockout of 2.5 percent during lead time.
