The one in bold, I already sold. Spartan Castings must implement a manufacturing process that reduces the amount of particulates emitted into the atmosphere. Two processes have been identified that provide the same level of particulate reduction. The first process is expected to incur $340,000 of fixed cost and add $40 of variable cost to each casting Spartan produces. The second process has fixed costs of $100,000 and adds $70 of variable cost per casting. a. What is the break-even quantity beyond which the first process is more attractive? The break-even quantity is 8000 castings. b. What is the difference in total cost if the quantity produced is 5,000? The total cost of process 1 is greater. Find the difference in total cost?
Dingizwe Manufacturing Corporation has a flat-file processing system. The information processing facility is very large. Different applications, such as order processing, production planning, inventory management, accounting systems, payroll, and marketing systems, use separate tape and disk files. The corporation has recently hired a consulting firm to investigate the possibility of switching to DBMS. REQUIRED: Prepare a memo to the top management team at Dingizwe explaining the advantages of a DBMS. Also, discuss the necessity of a database administrator and the job functions this person would perform
Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 5555% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,800 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $800 and a per loaf ingredient cost of $0.35 Current multifactor productivity for 640 work hours per month =0.27loaves/dollar (round your response to three decimal places).
An injector machine goes down roughly 20% of the time (the injector gums up and needs to be cleaned, a quick process). One operator is assigned to service three identical such machines. Each machine can produce 100 parts/h if running properly (i.e., not down). The operator is paid $10/h and each machine costs $20/h to operate. Consider 8hr/shift a) Please fill in the table below: b) How many parts can you produce per shift? c) What is the unit cost fper part for this operation? d) If you hire another operator at the same rate to assist the first operator, what is the unit cost now? e) Is it worth hiring another operator at the same rate to assist the first operator, in case more than one machine goes down at the same time?
The Holt Million Corporation’s plant manufactures two different products: X and Y. The plant has three different machines: A, B, and C. Each performs different tasks and can work on only one unit of material at a time. Details for each product are shown in the table below: Product X Y Demand Per Week 200 units 100 units Selling Price $150 $160 Machine Operation Required A, B, C B, B, C Operation Times in Minutes 20, 15, 15 15, 15, 15 Raw Materials Needed RM-1, RM-2 RM-2, RM-3 Raw Materials Costs RM-1 = $40/unit, RM-2 or RM-3 = $20/unit Each product uses raw materials with costs as shown in the above table where the processing times and the machine required for each operation are also shown. Each machine is available 4,800 minutes per week. There are no system foul-ups. Demand is deterministic (i. e., no uncertainty). Operating expenses, including labor (but excluding raw materials) total $12,000 per week. Assuming…

Manufacturing Company uses FIFO method of accumulating costs in a two-department process. Materials are introduced at the inception of the process except for a special material which is added in department 2 at 60% completion as to overhead. Inspection is done at the end of the process in both departments. Production data for Department 2 are given below: In process, beginning, (80% labor, 70% overhead)2,000 Transferred in 14,900 In process, ending (40% labor, 20% overhead) 3,000 Normal spoilage 200 Abnormal spoilage (found at 30% completion as to laborand 15% as to overhead due to internal failure) 400 Cost data for the month:In process beginning:Transferred in 15,020 Special materials 1,900 Direct labor 4,388 Overhead 11,044 Current costs:Transferred in 137,080 Special materials 14,030 Direct labor 46,000 Overhead 113,564 The cost of units transferred to finished goods is?The cost of spoilage charged to revenue is?
Mack’s guitar fabrication shop produces low cost, highly durable guitars for beginners. Typically, out of the 100 guitars that begin production each month, only 80 percent are considered good enough to sell. The other 20 percent are scrapped due to quality problems that are identified after they have completed the production process. Each guitar sells for $300. Because some of the production process is automated, each guitar only requires 10 labor hours. Labor is paid at $10/hour, materials cost is $40/guitar, and overhead is $2,000. a) Calculate the labor and multifactor productivities. b) After some study, the operations manager recommends 3 options to improve the company’s multifactor productivity: (1) increase the sales price by 10 percent, (2) improve quality so that only 10 percent are defective, or (3) reduce labor, material, and overhead costs by 10 percent. Which option has the greatest impact on the multifactor productivity measure?
CarCity is a big retailer for car parts and accessories. The store stocks different types and sizes of car tire. One of the best selling tires is the Tiger Model R125, which is currently purchased from a factory in Indonesia. An analysis of the purchasing operation shows that approximately 3 labor hours are required to process a purchase order, regardless of the quantity purchased. Salaries in the purchasing Department average OMR 12 per hour, including employee benefits. In addition, a detailed analysis of 15 previous purchase orders showed that OMR 132 was spent on telephone, paper, and other consumables directly related to the ordering process . Shipping cost from Indonesia is OMR 230 for a container. A container has a capacity of 800 tires. The lead time for shipments from Indonesia is 15 days. Finally, CarCity’s financial analysts established a holding cost of 20% for this type of tire. The annual demand for the R125 tire is constant at a rate of 8400 units. The store purchases…
