Question 2. A company is about to begin production of a new product. The manager of the department that produces 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 200 units a day. Eighty units are used daily in assembling the final product. Assembly takes 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 $300. Inventory holding costs will be $10 per unit. Round to the nearest whole number a. What run quantity will minimize total annual costs (EPQ)? b. What is the length of a production run in days? c. During production, how many units a day go to inventory as opposed to into production? d. What is the cycle time for optimal run time?

Question 2
Question 2. A company is about to begin production of a new product. The manager of the
department that produces 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 200 units a day. Eighty units are used daily in
assembling the final product. Assembly takes 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 $300. Inventory holding costs will be $10 per unit. Round to the nearest whole
number
a. What run quantity will minimize total
annual costs (EPQ)?
b. What is the length of a production run
in days?
c. During production, how many units a
day go to inventory as opposed to into
production?
d. What is the cycle time for optimal run
time?

Question 1. A large Tampa law firm uses an average of 40 boxes of copier paper a day. The
firm operates 260 days a year. Storage and handling costs for the paper are $30 a year per box,
and it costs approximately $60 to order and receive a shipment of paper. Round to the nearest
whole number
a. What order size would minimize the
sum of annual ordering and carrying costs
(EOQ)?
b. Compute the total annual cost using
your order size from part a.
c. Except for rounding, are annual
ordering and carrying costs always equal
at the EOQ?
d. The office manager is currently using
an order size of 200 boxes. The partners
of the firm expect the office to be
managed 'in a cost-efficient manner.'
Would you recommend that the office
manager use the optimal order size
instead of 200 boxes? Justify your
answer; you will need to determine the
total cost difference between the EOQ and
200 boxes/order.
