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 items 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?

Lindsay Electronics, a small manufacturer of electronic research equipment, has approximately 6,900 items in its inventory and has hired Joan Blasco-Paul to manage its inventory. Joan has determined that 12% of the items in inventory are A items, 34% are B items, and 54% are C items. She would like to set up a system in which all A items are counted monthly (every 22 working days), all B items are counted quarterly (every 62 working days), and all C items are counted semiannually (every 123 working days). How many items need to be counted each day?
The total number of items that need to be counted each day is _ items? (round response to the nearest whole number).
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.
Ray wishes to determine the optimal order quantity for its best-selling bike in his bike store. 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?

- 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?

Demand is projected to be 600 units for the first half of the year and 920 units for the second half.

- d. 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_forwardPeet'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?arrow_forwardCOMPUTING REORDER POINTS (ROP) FOR IPHONES WITH AND WITHOUT SAFETY STOCKAn Apple store has a demand (D) for 8,000 iPhones per year.

- Problem 20-40 (Algo) In the past, Taylor Industries has used a fixed−time period inventory system that involved taking a complete inventory count of all items each month. However, increasing labor costs are forcing Taylor Industries to examine alternative ways to reduce the amount of labor involved in inventory stockrooms, yet without increasing other costs, such as shortage costs. Here is a random sample of 20 of Taylor's items.

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.

HAL uses the drive housings at a fairly steady rate of 720per year. Suppose that the housings are shipped in trucks that can hold 40 housingsat one time. It is estimated that the fixed cost of loading the housings onto the truckand unloading them on the other end is $300 for shipments of 120 or fewer housings(i.e., three or fewer truckloads).
