6) Suppose that you have to decide between three mutually exclusive alternatives regarding the manufacturing techniques of the plant you are working in as an engineer. Following list is given: First investment (initial cost) Salvage value Operating cost per hour Useful life (year) Technique A ($) Technique B ($) 20,000 7,000 4 5 40,000 20,000 2 20 Technique C ($) 30,000 5,000 6 4 Here, system A, B, and operates 6, 12, and 20 hours a day, respectively. Assume that each are working 310 days per year. Assuming MARR is 12%, find the followings for each of these alternatives: a) Assuming a very long life for each, capitalized cost (CC)? b) Capital recovery (CR) c) Now suppose that revenue values for all are the same and given by $70,000. Which one would you prefer by using the AW analyses?
