2.4.1 Total Cost in Material SelectionIn many cases, economic selection among materials cannot be based solely on the costs ofmaterials. Frequently, a change in materials will affect the design and processing costs, and shipping costsmay also be altered.Care should be taken in making economic selections between materials to ensure that anydifferences in shipping costs, yields, or resulting scrap are taken into account. Commonly, alternativematerials do not come in the same stock sizes, such as sheet sizes and bar lengths. This may considerablyaffect the yield obtained from a given weight of material. Similarly, the resulting scrap may differ forvarious materials.In addition to deciding what material a product should be made of, there are often alternativemethods or machines that can be used to produce the product, which, in turn, can impact processingcosts. What could be the factors affecting the cost of materials that one should consider?
Determine the FW of the following engineering project when the MARR is 15% per year. Is the project acceptable? (5.4) *A negative market value means that there is a net cost to dispose of an asset. Investment cost Expected lifeMarket (salvage) value* Annual receiptsAnnual expenses $10,000 5 years -$1,000 $8,000 $4,000
13) The independent projects must have positive and negative cash flows to obtain a PW value that can exceed zero, which means that they must be revenue projects. Select one: True False 14) capitalized cost is considered as the present worth of projects that has a short life or when the planning horizon is very short. Select one: True False
A food processing plant consumed 600,000 kW of electric energy annually and pays an average ofP2.00 per kWh. A study is being made to generate its own power to supply the plant the energy required, and that the power plant installed would cost P2,000,000. Annual operation andmaintenance,P800,000. Other expenses P100,000 per year. Life of power plant is 15 years; salvage value at the end of life is P200,000 annual taxes and insurances, 6% of first cost; and rate of interest is 15%. Using the sinking fund method for depreciation, determine if the power plant is justifiable. Compute using the present worth, annual worth, and rate of return.
Respond to the question with a concise and accurate answer, along with a clear explanation and step-by-step solution, or risk receiving a downvote. A company wants to buy a production device for their new factory. They have two alternatives, whose cash flows are given in the following table. Salvage value is 20% of the initial cost. According to these cash flows, choose the best alternative knowing their payback periods. Alternative A Alternative B Initial Cost Annual Income Useful Life P3,000,000 P3,500,000 P1,200,000 P1,000,000 4 vears 8 years
Mustang Auto Parts, Inc. is considering one oftwo forklift trucks for its assembly plant.• Truck A costs $15,000 and requires $3,000 annually in operating expenses. It will have a $5,000salvage value at the end of its three-year servicelife.• Truck B costs $20,000, but requires only $2,000annually in operating expenses; its service life isfour years, at which time its expected salvage valuewill be $8,000.The firm’s MARR is 12%. Assuming that the trucksare needed for 12 years and that no significantchanges are expected in the future price and functional capacity of each truck, select the most economical truck on the basis of AE analysis.
As a Project Engineering had been tasked to make an analysis and to recommend to yourcompany on the economic justification on option to purchase a new or 3-year old used truck tobe used for the company's project construction activities as well as providing some rentalbusiness for three years. As the truck is not used for the whole time, 5-days a month it is beingrented out. The new truck having better fuel efficiency and lower maintenance cost. Based onyour data gathering, you have this information derived for the analysis.(Refer to attached image) b) Based on Payback Period evaluation, which unit will you recommend to your management to be purchased and why?
During your first month as an employee at Engro. Industries (a large drill-bit manufacturer),you are asked to evaluate alternatives for producing a newly designed drill bit on a turningmachine. Your boss’ memorandum to you has practically no information about what thealternatives are and what criteria should be used. The same task was posed to a previousemployee who could not finish the analysis, but she has given you the following information:An old turning machine valued at $350,000 exists (in the warehouse) that can be modified forthe new drill bit. The in-house technicians have given an estimate of $40,000 to modify thismachine, and they assure you that they will have the machine ready before the projected startdate (although they have never done any modifications of this type). It is hoped that the oldturning machine will be able to meet production requirements at full capacity. An outsidecompany, Descon Engg. Inc., made the machine seven years ago and can easily do the…
The following are data from a production, calculate; The Break-even point in terms of sales value and in . The production demand is at 20,000 units. What is the cw1ent production profit? If the management decides to lower dow11its selling price by 50% given the same demand, will this be a sound decision? Justify. Monthly Fixed Factory Overhead Cost = P600,000 Monthly Fixed Selling Overhead Cost = Pl20,000 Va1iable Manufacturing Cost per Unit = P220 Va1iable Selling Cost per Unit = P30 Variable Distribution Cost per Units = P50 Selling Price per limit = P400
