Johnson Tire Plaza (JTP) is a large chain of tire shops, who sells various brand of automobile tires. The yearly demand of a particular brand of time is about 10,821 units per year. JTP purchases these tires from a supplier. The ordering cost is $109 per order and the holding cost is $14.6 per tire per year. The supplier always delivers the shipment within 13 days after receiving a replenishment order from JTP. The company operates 250 days per year. Assume EOQ model is applicable.
What is the number of orders per year if JTP uses an order quantity of 1,728 tires? Use at least 4 decimal places.
A restaurant uses 5,000 quart bottles of ketchup each year. The ketchup costs $3.00
per bottle and is served only in whole bottles because its taste quickly deteriorates. The
restaurant figures that it costs $10.00 each time an order is placed, and holding costs
are 20 percent of the purchase price. It takes 3 weeks for an order to arrive. The
restaurant operates 50 weeks per year. The restaurant would like to use an inventory
system that minimizes inventory cost. The restaurant has figured that the most
economical order size or EOQ is approx. 409 (rounding up the decimals).
Suppose that things have become uncertain and that customer demand is no more
constant. Customer demand is now normally distributed with mean being the same as
given in the problem description and standard deviation = 30 units per week. The
supply source is still very reliable and as a result the lead time is constant. Find out the
safety stock needed to achieve 95% customer service level.

A grocery store company specializing in rare and expensive foods is
considering operating under a backorder policy for a particular kind of Bel-
gian cheese. The company currently operates with no backorders. It costs
the company $75 to place an order with the Belgian manufacturer, and pays
$1500 per wheel of cheese, with a 20% annual holding cost per wheel. De-
mand for the cheese is on average 1 wheel of cheese per week. The company
operates the store 50 weeks per year.
(a) What is the economic order quantity that minimizes yearly inventory
cost (with no backorders)?
(b) What is the total cost to operate this inventory policy?
Page 3 of 8
(c) The company proposes allowing backorders. It will compensate cus-
tomers by providing them a discount and promising home delivery. The
company estimates the backorders will cost $680 per wheel of cheese.
What is the new economic order quantity and planned backorder quan-
tity under the new policy?
(d) What is the total cost of the backorder…

The demand for bolts is fairly constant; on the average, the manager, Michelle Wu, has observed that the hardware store sells 500 of these bolts each day. Because the demand is fairly constant, Michelle believes that she can avoid stockouts completely if she orders the bolts at the correct time. What is the reorder point? The reorder point is? units (enter your response as a whole number).arrow_forward
- Cooler Corporation is a manufacturer of cooling products. It purchases 14,400 units of a particular component (CK55) each year at a cost of $60 per unit. Cooler Corporation requires a 12% annual rate of return on investment.

Monthly demand for cans of white paint is normal with mean 28 and standard deviation 8. The replenishment lead time is 14 weeks. Excess demand is backordered, but costs $10 per back ordered can in labor and loss of goodwill. There is a fixed cost of $15 per order, and the holding cost is based on 30% interest rate per annum. In your computations, assume 4 weeks per month. - Write down the model name and parameters. - What are the optimal lot size and reorder points for white paint (include the formulas)? - What is the optimal safety stock (include the formula)? *** Suppose the paint shop from the above problem adopts a service level policy. - What are the optimal lot size and reorder points for white paint, such that 90% of the cycles are filled without backordering (include all formulas)? - What is the fill rate…arrow_forward
