Chapter 12, Problem 4P
Lindsay Electronics, a small manufacturer of electronic research equipment, has approximately 7,000 items in its inventory and has hired Joan Blasco-Paul to manage its inventory. Joan has determined that 10% of the items in inventory are A items, 35% are B items, and 55% are C items. She would like to set up a system in which all A items are counted monthly (every 20 working days), all B item are counted quarterly (every 60 working days), and all C items are counted semiannually (every 120 working days). How many items need to be counted each day?

The Western Jeans Company purchases denim from Cumberland Textile Mills. The Western Jeans Company uses 35,000 yards of denim per year to make jeans. The cost of ordering denim from the textile company is $500 per order. It costs Western $0.35 per yard annually to hold a yard of denim in inventory. Determine the optimal number of yards of denim the Western Jeans Company should order, the minimum total annual inventory cost, the optimal number of orders per year, and the optimal time between orders.
Peet's Coffees in Menlo Park, California, sells Melitta Number 101 coffee filters at a fairly steady rate of about 60 boxes of filters monthly. The filters are ordered from a supplier in Trenton, New Jersey. Peet's manager is interested in applying some inventory theory to determine the best replenishment strategy for the filters. Peet's pays $2.80 per box of filters and estimates that fixed costs of employee time
for placing and receiving orders amount to about $20. Peet's uses a 22 percent annual interest rate to compute holding costs. b. Suppose that it takes three weeks to receive a shipment. What inventory of filters
should be on hand when an order is placed?

Ray pays the supplier a wholesale price of $118 each for this bike. Ray has estimated the average daily demand for this bike is 23 units. The store opens 304 days a year. The cost to carry one bike in the store for a whole year is 8% of the unit bike cost. Ray has estimated that, on average, the order processing cost, i.e., ordering cost, with the bike supplier each time is $152, and it roughly takes 20 working days to receive the order from the supplier. Ray wishes to avoid the stock-out situation with a probability of 95%, and this requires Ray to carry a safety stock of 30 bikes in the store. What is the optimal order quantity (EOQ value) that Ray should order each time from the bike supplier to minimize his long-run inventory cost?arrow_forwardHappy Pet, Inc., is a large pet store located in LongBeach Mall. Although the store specializes in dogs, it a lso sellsfish, turtle, and bird supplies. The Everlast Leader, a leather leadfor dogs, costs Happy Pet $7 each. There is an annual demand for6,000 Everlast Leaders. The manager, Stephan Wagner, has determinedthat the ordering cost is $20 per order and the carrying cost,as a percentage of unit cost, is 15%. Happy Pet is now consideringa new supplier of Everlast Leaders. Each lead would cost only$6.65, but, in order to get this discount, Happy Pet would have tobuy shipments of 3,000 at a time. Should Happy Pet use the newsupplier and take this discount for quantity buying?arrow_forward

- Kris Lee, the owner and manager of the Quality Hardware Store, is reassessing his inventory policy for hammers. He sells an average of 50 hammers per month, so he has been placing an order to purchase 50 hammers from a wholesaler at a cost of $20 per hammer at the end of each month. However, Kris does all the ordering for the store himself and finds that this is taking a great deal of his time. He estimates that the value of his time spent in placing each order for hammers is $75. What would the unit holding cost for hammers need to be for Kris' current inventory policy to be optimal according to the basic EOQ model? What is this unit holding cost as a percentage of the unit acquisition cost? What is the optimal order quantity if the unit holding cost actually is 20 percent of the unit acquisition cost? What is the corresponding value of TVC? What is TVC for the current inventory policy?

The weekly average inventory listed above cannot change much since the grocery store is limited in storage capacity, and can therefore assumed to remain constant over time. The store has calculated that having less than 3 weeks of supply will create problems keeping stock available for clients. What annual cost of goods sold will bring about this condition (3 weeks of supply)?e. The grocery store is increasingly popular and management has calculated that, on average, the cost of goods sold increase by $5 million per year, reflecting better sales. How many years will it take for the grocery store to require expansion?arrow_forwardCassie Company manufactures a line of deluxe office fixtures. The annual demand for its miniature oak file is estimated to be 5,000 units. The annual cost of carrying one unit in inventory is P10, and the cost to initiate a production run is P1,000. There are no miniature oak files on hand, and Cassie has scheduled four equal production runs of the miniature oak file for the coming year, the first of which is to be run immediately. Cassie has 250 business days per year. Assume that sales occur uniformly throughout the year and that production is instantaneous. If Cassie does not maintain a safety stock, the estimated total carrying costs for the office fixtures for the coming year based on their current schedule is Answer: Refer to Cassie, the number of production runs per year of the miniature oak files that would minimize the sum of carrying costs and setup costs for the coming year is Answer:arrow_forward
