You run a food bar in UCLA Ackerman, and you sell chocolate croissants for breakfast. Your daily demand for chocolate croissants is on average 50, with a standard deviation of 8. The unit cost of a croissant is $0.70, and you sell at a unit price of $3.00. The refrigerated chocolate croissant must be consumed within 7days (one week) after purchased from your supplier, so you dispose leftover inventory and purchase fresh croissants once every week. Assume the demand in each of the seven days is independently distributed. (The z-table for normal distribution is attached.)
(a) What is the optimal weekly purchase quantity for the chocolate croissant? What is average inventory?
A student leader, Mark, came to you one day and told you that Anderson School would hold a special event next Thursday morning, and there would be additional demand for the chocolate croissant on that day. Mark wants to reserve a certain amount of croissant from you and sell in the special event at the regular price.…
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.
A large manufacturer purchases a part from a supplier under a continuous review system. The average demand is 400 units a day with a standard deviation of 50 units a day. It costs $55 to process each order.
The holding cost for a part is $0.2 per month and the company has a policy of maintaining a 96% service level. The company operates 315 days per year. The time from when an order is placed to when it arrives at the company from its vendor is 5 days.
a- What is the reorder point?
b- What order quantity would be appropriate
c- What is the total annual cost for this item?

- 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_forwardMunabhaiarrow_forwardMytown’s street department repaves a street every 8 years.

- The army is attempting to determine the optimal replacement age for a piece of field equipment. The equipment costs $280,000 to replace. The manufacturer will supply a rebate toward the next purchase that declines at a rate of 20 percent per year. Maintenance costs for the first year are estimated to be $1,000, and they increase roughly at the rate of 18 percent per year. Estimate the number of years that the army should hold the equipment before making a replacement.(Production and Operation Analysis by Steven Nahmias, 7th edition, pg.774 Problem # 24)arrow_forwardYour County has asked you to analyze the purchase of some dump trucks. Each truck wil cost $45,000 and have an operating and maintaining cost that starts at $15,000 the first year and increases by $ 2,000 per year.

- The Bosch factory in New Bern, NC uses dishwasher motors at a steady rate of 17308 units per year. Bosch procures these units from a supplier at a purchase cost of $58 per unit. Bosch receives an order 26 days after it is placed. Regardless of the number of units ordered, Bosch incurs a fixed cost of $2988 for placing, shipping, and receiving the order. The holding cost per unit per year is 30% of the purchase cost per unit. Assume Bosch operates 364 days, 52 weeks, or 12 months per year. Calculate the average time a unit spends in inventory between orders in DAYS for the optimal order quantity from the problem above.

He learned that the steak was replenished using an EOQ value of 2,000 pounds. The EOQ value was computed assuming an interest rate of 36 percent per year. Assume that the current cost of the sirloin steak to the steak house is $4 per pound.a. What is the setup cost used in determining the EOQ value? Mr. Hirai received an offer from a meat wholesaler in which a discount of 5 percentwould be given if the steak house purchased the steak in quantities of 3,000 pounds or more.b. Should Mr. Hirai accept the offer from the wholesaler? If so, how much can be saved?c. Because of Mr. Hirai’s language problems, he apparently misunderstood the offer. In fact, the 5 percent discount is applied only to the amounts ordered over 3,000 pounds. Should this offer be accepted, and if so, how much is now saved?arrow_forward
