A logistics company applies the EOQ model to manage its inventory of spare parts
used for maintenance work for their trucks. Daily demand is normally distributed.
The average daily demand is 10 units, with a standard deviation of 5 units. The EOQ
is found to be 400 units and used as the order size for all orders. Order lead time is 4
days.
Currently, the firm has just received an order. In how many days do they need to
place the next order?
4 days
36 days
40 days
None of the above. Demand is random, so the time until they reach the ROP
again is also random

A manufacturer has a production facility that requires 15,604 units of component JY21 per year.
Following a long-term contract, the manufacturer purchases component JY21 from a supplier with a
lead time of 7 days. The unit purchase cost is $25.6 per unit. The cost to place and process an order
from the supplier is $121 per order. The unit inventory carrying cost per year is 10.5 percent of the
unit purchase cost. The manufacturer operates 250 days a year. Assume EOQ model is appropriate. If
the manufacturer uses a constant order quantity of 2,640 units per order, what is the annual holding
cost?
Use at least 4 decimal places.

- Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.arrow_forwardDaily demand of a chemical at an oil refinery is normally distributed with a mean of 60 litres and a standard deviation of 7. The supplier reliably delivers the chemical by maintaining a constant lead time of 1 week. There are no delivery charges from the supplier. Sales occur throughout the year. An order placement requires one hour of an administrative employee who is paid $20 per hour. Receiving and storing a chemical shipment requires two workers to work for half an hour. Workers are paid $12 per hour each. Chemical’s purchase price is $500 per litre. Annual cost of capital is 5%. Other holding costs are estimated to be $0.5 per litre.

The most popular frame style is sold at $50 per unit and it costs Bigby $35 per piece. If too many art frames are ordered, Bigby incurs an inventory carrying cost of $2 per frame. If Bigby runs out of stock for the week, he forgoes the profits from missed sales. Bigby has the option to order 100, 150, or 200 art frames to meet next week's demand which can be either 100, 150, or 200 frames.
