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.

- Flemming Accessories produces paper slicers used in offices and in art stores. The minislicer has been one of its most popular items: Annual demand is 6,750 units and is constant throughout the year. Kristen Flemming, owner of the firm, produces the minislicers in batches. On average, Kristen can manufacture 125 minislicers per day. Demand for these slicers during the production process is 30 per day. The setup cost for the equipment necessary to produce the minislicers is $150. Carrying costs are $1 per minislicer per year. How many minislicers should Kristen manufacture in each batch?arrow_forwardA certain piece of production equipment is used to produce various components for an assembled product of the XYZ Company. To keep in-process inventories low, it is desired to produce the components in batch sizes of 150 units (daily requirements for assembly). Demand for each product is 2500 units per year. Production downtime costs an estimated $200/hr. All of the components made on the equipment are of approximately equal value: Cp = $9.00/unit. Holding cost rate = 30%/yr. In how many minutes must the changeover (setup) between batches be completed in order for 100 units to be the economic order quantity?arrow_forwardItem X is a standard item stocked in a company’s inventory of spare parts. Each year, the firm uses about 2,000 units of Item X, which costs Php 1,000 per unit. Storage costs, which include insurance and cost of capital, amount to 18 percent of item unit cost. Placing an order for more of Item X costs Php 400. The company operates 360 days per year and Item X is received 9 days after placement of order. How many units of Item X should be ordered each time? When should Item X be ordered? How much would be Item X's total annual purchasing cost? How much would be Item X's total annual procurement cost? Including its total annual purchasing cost, how much would be Item X's total annual inventory cost? What is Item X's average inventory level? How much would be Item X's total annual storage cost?

- The daily demand for printer paper at the School of Business is approximately normal with a mean of 15.2 boxes and a standard deviation of 1.6 per day. The Administrative Assistant reviews the inventory every 30 days, and the lead time is 5 days. The division set a policy of satisfying 96% of the demand for paper. If there are 125 boxes of printer paper in inventory at the beginning of this review period, how many boxes of printer paper should be ordered? What is the variance of demand during the review period plus the lead-time period? What is the standard deviation of demand during the review period plus the lead-time period? A. Variance = 76.80 Standard deviation = 8.76 B. Variance = 89.60 Standard deviation = 9.47 C. Variance = 9.47 Standard deviation = 89.60 D. Variance = 12.8 Standard deviation = 3.58arrow_forwardItem X is a standard item stocked in a company's inventory of spare parts.

It anticipates receiving a lot of 3,000 chips in week 3 from another firm that has gone out of business.At the current time, Noname purchases the chips from two vendors, A and B. A sells the chips for less, but will not fill an order exceeding 10,000 chips per week.a. If Noname has established a policy of inventorying as few chips as possible, what order should it be placing with vendors A and B over the next six weeks?b. Noname has found that not all the DRAM chips purchased function properly. From past experience it estimates an 8 percent failure rate for the chips purchased from vendor A and a 4 percent failure rate for the chips purchased from vendor B.
