Concept explainers
(a)
Interpretation: The number of pies required for each production run is to be calculated along with the annual cost of setup and the holding cost of the pies.
Concept Introduction:
Economic order quantity (EOQ) refers to the ideal order quantity that an organization should buy to minimize inventory costs such as ordering costs, holding costs, and shortage costs.
(b)
Interpretation: The total optimal number of pies that should be baked each time in the new oven is to be calculated.
Concept Introduction:
Inventory management is nothing but the holding, ordering, and utilizing the organization’s inventory. This includes the management of the organization’s resources, raw material, components, and finished goods.
(c)
Interpretation: The number of years will it require for the new oven to pay for itself is to be calculated when the cost of the new oven is $350.

- Because Home-Style does not use preservatives in their cookies, shelf life is an issue. Therefore, Home-Style runs small batches of cookies in order to meet demand but not have excess inventory. The production team schedules batches of chocolate chip cookies every three days. They adjust the number of cookies per production run in order to meet projected demand. For a standard run of 2,000 chocolate chip cookies, they use: 19 cups all-purpose flour 7 teaspoons salt 7 teaspoons baking powder 7 teaspoons baking soda 17 sticks unsalted butter, softened 12 cups packed dark brown sugar 1 3/4 cup granulated sugar 14 large eggs 14 teaspoons vanilla extract 14 cups semisweet chocolate chips Which ingredients are the most perishable and would need to be ordered more frequently? What could the operations manager do to minimize the reorder lead time for these in-demand perishable ingredients? What could Home-Style do to ensure all cookies are sold before their 3-day shelf life expires? What could…arrow_forwardThe Big Buy Supermarket stocks Munchies Cereal. Demand for Munchies is 4,000 boxes peryear (365 days). It costs the store $60 per order of Munchies, and it costs $0.80 per box per yearto keep the cereal in stock. Once an order for Munchies is placed, it takes 4 days to receive theorder from a food distributor. Determine The optimal order sizearrow_forwardA local machine shop buys hex nuts and molly screws from the same supplier. The hex nuts cost 15 cents each and the molly screws cost 38 cents each. A setup cost of $100 is assumed for all orders. This includes the cost of tracking and receiving the orders. Holding costs are based on a 25 percent annual interest rate. The shop uses an average of 20,000 hex nuts and 14,000 molly screws annually.a. Determine the optimal size of the orders of hex nuts and molly screws, and the optimal time between placement of orders of these two items.b. If both items are ordered and received simultaneously, the setup cost of $100 applies to the combined order. Compare the average annual cost of holding and setup if these items are ordered separately; if they are both ordered when the hex nuts would normally be ordered; and if they are both ordered when the molly screws would normally be ordered.arrow_forward
- Berry Computer is considering moving some of its operations overseas in order to reduce labor costs. In the United States, its main circuit board costs Berry $75 per unit to produce, while overseas it costs only $65 to produce. Holding costs are based on a 20 percent annual interest rate, and the demand has been a fairly steady 200 units per week. Assume that setup costs are $200 both locally and overseas. Production lead times are one month locally and six months overseas.a. Determine the average annual costs of production, holding, and setup at each location, assuming that an optimal solution is employed in each case. Based on these results only, which location is preferable?b. Determine the value of the pipeline inventory in each case. (The pipeline inventory is the inventory on order.) Does comparison of the pipeline inventories alter the conclusion reached in part (a)?c. Might considerations other than cost favor local over overseas production?arrow_forwardA manager receives a forecast for next year. Demand is projected to be 600 units for the first half of the year and 920 units for the second half. The monthly holding cost is $2 per unit, and it costs an estimated $55 to process an order. a.Assuming that monthly demand will be level during each of the six-month periods covered by the forecast (e.g., 100 per month for each of the first six months), determine an order size that will minimize the sum of ordering and carrying costs for each of the six-month periods.

The demand for cameras at B&H is 200 cameras per week. Each time that B&H places an order for a new shipment of cameras, it must pay $80 in fixed processing fees. A camera costs B&H $60 to purchase. The cost for B&H to hold a camera in its store for one week is $4. Assume that the lead time for the delivery of a camera is 0 weeks.a. Suppose that B&H places orders for cameras in quantities of 50 cameras at a time and places a new order for cameras each time that it runs out. Draw a graph showing the number of cameras that B&H has on-hand in inventory at each point in time up until the time when it places its fourth-order. Label the points in time at which B&H places a new order. Assume that B&H places its first order for 50 cameras on day 0.b. Suppose again that B&H places orders for 50 cameras at a time.

Assume that the demand is constant throughout the year. QUESTION: How many number 6 screws should Lia order at a time if she wishes to minimize total inventory cost?arrow_forward
- Consider the coffeehouse discussed below. Suppose that its setup cost for ordering was really only $15. Determine the error made in calculating the annual cost of holding and setup incurred as a result of its using the wrong value of K. (Note that this implies that its current order policy is suboptimal.) A specialty coffeehouse sells Colombian coffee at a fairly steady rate of 280 pounds annually. The beans are purchased from a local supplier for $2.40 per pound. The coffeehouse estimates that it costs $45 in paperwork and labor to place an order for the coffee, and holding costs are based on a 20 percent annual interest rate.arrow_forwardHelp need. management accounting Lebar Daun Sdn Bhd is planning to use the economic order quantity model to determine the optimal order levels of raw materials. Material Z is consumed evenly over the year and the current usage is 120,000 units. The material is purchased in boxes and each box contains 12 units of material Z, at a price of RM252 per box. A safety stock of 200 boxes is kept. The cost of placing and handling orders is estimated to be RM6,300, which is based cost incurred for similar orders that have already made. The cost of RM6,300 was for 30 orders. The inflation of 2 per cent should be added to the above ordering costs. Besides, the company estimates to be charged the transporation cost of RM15 per order. It should be assumed that ordering costs change in proportion to the number of orders place. Other costs which relate to material Z such as insurance, interest and space costs for a year, were calculated at 15 % of the purchase price. Required: a.
