Chapter 4.7, Problem 24P
Summary Introduction
Interpretation: the optimal order quantity
Concept introduction: EOQ is calculated on two costs, ordering costs, i.e. the cost of placing an order or cost of acquiring inventory, and carrying costs or holding costs ,i.e. The cost of keeping the inventory in the firm, like store keeping costs, obsolescence losses, rent of storage facility etc. EOQ gives us the balance between these two costs as these costs are inversely related to each other.

The sales of Whole Care mouthwash at Jen's of Michigan over the past six months have averaged 2,000 cases per month, which is the current order quantity. Jen's of Michigan's cost is $12.00 per case, and ordering cost is $38. The company estimates its cost of capital to be 12 percent. Insurance, taxes, breakage, handling, and pilferage are estimated to be approximately 6 percent of the item cost. Lead time is 3 days, and considering weekends and holidays, Tom's of Maine operates 250 days per year.
Based on the above information please answer the following questions
What is EOQ?
What is the cost reduction?
What is the reorder point?
What is Time between Orders (TBO)?
The purchasing agent for a company that assembles and sells air-conditioning equipment in a Latin American country noted that the cost of compressors has increased significantly each time they have been reordered. The company uses an EOQ model to determine order size. What are the implications of this price escalation with respect to order size? What factors other than price must be taken into consideration?

- (a) Ignoring taxation, calculate the optimum order level of inventory over a one-year planning period using the EOQ model. (b) Estimate the level of safety inventory that should be carried by Toyzrfun Ltd. (c) If Toyzrfun Ltd were to be offered a quantity discount by its suppliers of 1% for orders of 30 000 units or more, evaluate whether it would be beneficial for the company to take advantage of the quantity discount. Assume for this calculation that no safety inventory is carried. (d) Estimate the expected total annual costs of inventory management if the EOQ had been (i) 50% higher, and (ii) 50% lower than its actual level.

- I need a detailed explanation on how to solve this problem: A paint shop implements an inventory policy on its stock of white paint, which costs the store $6 per can. Monthly demand for cans of white paint is normal with mean 28 and standard deviation 8. The replenishment lead time is 14 weeks. Excess demand is backordered, but costs $10 per back ordered can in labor and loss of goodwill. There is a fixed cost of $15 per order, and the holding cost is based on 30% interest rate per annum. In your computations, assume 4 weeks per month. - Write down the model name and parameters. - What are the optimal lot size and reorder points for white paint (include the formulas)? - What is the optimal safety stock (include the formula)? *** Suppose the paint shop from the above problem adopts a service level policy. - What are the optimal lot size and reorder points for white paint, such that 90% of the cycles are filled without backordering (include all formulas)? - What is the fill rate…arrow_forwardSuppose Stanley's Office Supply purchases 50,000 boxes of pens every year. Ordering costs are $100 per order and carrying costs are $0.40 per box. Moreover, management has determined that the EOQ is 5,000 boxes. The vendor now offers a quantity discount of $0.20 per box if the company buys pens in order sizes of 10,000 boxes. Determine the before-tax benefit or loss of accepting the quantity discount. (Assume the carrying cost remains at $0.40 per box whether or not the discount is taken.)arrow_forwardThe maintenance department of a large hospital uses about 816 cases of liquid cleanser annually.

- Annual demand for a product is 11,960 units; weekly demand is 230 units with a standard deviation of 50 units. The cost of placing an order is $125, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.80 per unit. To provide a 98 percent service probability, what must the reorder point be? Suppose the production manager is told to reduce the safety stock of this item by 125 units. If this is done, what will the new service probability be?arrow_forwardEach year, Y Company purchases 20,000 units of an item that costs $640 per unit. The cost of placing an order is P 480, and the cost to hold the item in inventory for one year is $150. Determine the EOQ. What is the average inventory level, assuming that the minimum inventory level is zero Determine the total annual ordering cost and the total annual holding cost for the item if the EOQ is used.arrow_forwardAn engineer has decided to pursue ordering option for a particular item on an as needed basis as oppose to stocking it. To stock the item, inventory inspection costs $500 annually. The cost to place an order is estimated at $125. For the ordering option, there is an additional $85 special delivery charge per order. Demand for the $20 item is 2,300 units per year. The annual holding cost rate is 40% of the item price. Calculate range of the order quantity that will make it economical to order this item every time. If the engineer decides to stock the item what is the order quantity that is economical.arrow_forward
