Concept explainers
a)
To calculate: The EOQ.
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.
b)
To calculate: The EOQ when holding cost is doubled.

- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.arrow_forwardSoutheastern Bell stocks a certain switch connector at its central warehouse for supplying field service offices. The yearly demand for these connectors is 15,000 units. Southeastern estimates its annual holding cost for this item to be $24 per unit. The cost to place and process an order from the supplier is $73. The company operates 300 days per year, and the lead time to receive an order from the supplier is 3 working days.arrow_forwardYellow Press, Inc., buys paper in 1,500-pound rolls for printing. Annual demand is 3,000 rolls. The cost per roll is $1,000, and the annual holding cost is 28 percent of the cost. Each order costs $75. Part 2 a. How many rolls should Yellow Press order at a time? Yellow Press should order enter your response here rolls at a time. (Enter your response rounded to the nearest whole number.) Part 3 b. What is the time between orders? (Assume 200 workdays per year.) The time between orders is enter your response here days. (Enter your response rounded to one decimal place.)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_forwardAbey Kuruvilla, of Parkside Plumbing, uses 1,200 of a certain spare part that costs $25.00 for each order, with an annual holding cost of $24.00. a) Calculate the total cost for order sizes of 25, 40, 50, 60, and 100 (round your response to the nearest whole number). b) What is the economic order quantity? units (round your response to the nearest whole number).

It costs RO 10 to make and receive an order, and it takes 16 work days to receive it. The annual holding cost is 15 % of purchase price. The price RO 1 per kg. The company is operating 6 days per week. What is the economic order quantity (EOQ)? Round-up to the nearest integer- Select one: a. 593 kg b. 693 kg c. 690 kg d. 267 kgarrow_forward
- You are the operations manager of a firm that uses the continuous review (EOQ) system to control your inventory. Suppose the firm operates 52 weeks per year, 365 days, and has the following characteristics for its primary item: Demand = 25,000 units/year %3D Ordering Cost = $30/order Holding Cost = $8/unit/year Lead Time = 2 weeks Standard Deviation in weekly demand = 100 units %3D What is the economic order quantity for this item? Between 400 and 450 units O Between 450 and 500 units Fewer than 400 units O Greater than 500 unitsarrow_forwardHi Tech Corporation (HTC) expects to order 295,000 memory chips for inventory during the coming year, and it will use this inventory at a constant rate. Fixed ordering costs are $300 per order; the purchase price per chip is $32; and the firm’s inventory carrying costs is equal to 18 percent of the purchase price. EOQ=2309.75. If HTC is able to negotiate a reduction in the fixed ordering costs to $250.00 per order, but HTC decides to carry a safety stock of 28 days of memory chip sales. With the reduced fixed ordering cost and the increased average inventory due to the safety stock carried, what is the additional total inventory costs due to the decision to balance out uncertainty by carrying the specified safety stock?arrow_forwardGiven the following information, formulate an inventory management system. The item is demanded 50 weeks a year. PARAMETER Item cost Order cost Annual holding cost Annual demand Average weekly demand Standard deviation of weekly demand. Lead time. Service probability Optimal order quantity Reorder point units units VALUE $12.00 $194.00/order 21% of item cost 24,700 units 494 /week 20 units 2 week 95% a.
