Concept explainers
a)
To determine: The total annual cost for different order sizes.
Introduction:
Total cost of inventory:
The total cost involved in ordering and carrying an inventory and the costs associated with the management and handling of associated activities.
b)
To calculate: The economic order quantity (EOQ) and to determine the implications of making error in calculating economic order quantity.
Introduction:
Economic order quantity (EOQ):
EOQ is the quantity of units a company must add to its inventory so as to minimize the total inventory costs. It will determine the ideal order quantity which will decrease the inventory management costs.

- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.arrow_forwardEpworth Co. predicts that it will use 360,000 gallons of material during the year. It anticipates that it will cost $72 to place each order. The annual carrying cost is $4 per gallon. a. Determine the most economical order quantity by using the EOQ formula. b. Determine the annual order and carrying costs at the EOQ point.arrow_forwardAbey Kuruvilla, of Parkside Plumbing, uses 1,250 of a certain spare part that costs $26 for each order, with an annual holding cost of $27. a) Calculate the total cost for order sizes of 25, 40, 50, 60, and 100 (round your responses to two decimal places). b) What is the economic order quantity? units (round your response to two decimal places).arrow_forward
- The materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. She knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. She also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four days. If the order size was 1,000 kilograms of resin, what would be the average inventory level?arrow_forward21. The expected annual usage of a particular material is 540,000 units, and the standard order size is 36,000 units The invoice cost of each unit is P900, and the ordering cost per order is P240. Assuming the company does not maintain safety stock. What is the ordering cost?arrow_forwardGiven the following information, compute the economic order quantity, annual holding cost, annual order cost, and annual total inventory cost. Annual requirements (R) = 50,000 units Order cost (S) = $150 per order Holding rate (k) = 15% Unit cost (C) = $100 per unitarrow_forward
- Corry Corporation purchases 1,200,000 unit per year of one component. The Fixed Cost per order is $25. The annual carrying cost of the item is 27% of its $2 cost. Show Computations and Explanations. Determine the EOQ under each of the following conditions: A. Using the same data above, compute the EOQ. (Format: 11,111) B. What if the order cost is zero, what is the EOQ?

The owner, David Gold, estimates that the demand for the salamis is pretty steady at 175 per month. The salamis cost Gold $1.85 each. The fixed cost of calling his brother in New York and having the salamis flown in is $200. It takes three weeks to receive an order. Gold's accountant, Irving Wu, recommendsan annual cost of capital of 22 percent, a cost of shelf space of 3 percent of the value of the item, and a cost of 2 percent of the value for taxes and insurance. How many salamis should Gold have on hand when he phones his brother to send another shipment?arrow_forwardWalrus Company has the following information available concerning one of its inventory items: Cost of placing an order $30.00 Unit carrying cost per year $3.00 Annual unit demand 6,625 Safety stock 125 Average daily demand 25 Normal lead time in days 10 If there is a delay in shipping the item, approximately how many days can be covered by the safety stock? a.5 days b.110 days c.26 days d.31 daysarrow_forward
- Ottis, Inc., uses 640,000 plastic housing units each year in its production of paper shredders. The cost of placing an order is $30. The cost of holding one unit of inventory for one year is $15.00. Currently, Ottis places 160 orders of 4,000 plastic housing units per year. Compute the economic order quantity. Economic order quantity = 1600 Compute the ordering, carrying, and total costs for the EOQ. How much money does using the EOQ policy save the company over the policy of purchasing 4,000 plastic housing units per order?arrow_forwardDiscount-Mart, a major East Coast retailer, wants todetermine the economic order quantity (see Chapter 12 for EOQformulas) for its halogen lamps. It currently buys all halogenlamps from Specialty Lighting Manufacturers in Atlanta. Annualdemand is 2,000 lamps, ordering cost per order is $30, and annualcarrying cost per lamp is $12. a) What is the EOQ?b) What are the total annual costs of holding and ordering(managing) this inventory?c) How many orders should Discount-Mart place with SpecialtyLighting per year?arrow_forwardEOQ, reorder point, and safety stock Alexis Company uses 916 units of a product per year on a continuous basis. The product has a fixed cost of $60 per order, and its carrying cost is $3 per unit per year. It takes 5 days to receive a shipment after an order is placed, and the firm wishes to hold 10 days' usage in inventory as a safety stock. a. Calculate the EOQ. b. Determine the average level of inventory. (Note: Use a 365-day year to calculate daily usage.) c. Determine the reorder point. d. Indicate which of the following variables change if the firm does not hold the safety stock: (1) order cost, (2) carrying cost, (3) total inventory cost, (4) reorder point, (5) economic order quantity. a.
