As supervisor of a facilities engineering department, you consider mobile cranes to be critical equipment. The purchase of a new, medium-sized truck-mounted crane is being evaluated. The economic estimates for the two best alternatives are shown in the following table. MARR is at 15% per year. You can use the assumption of repeatability in this case.
Show that the same selection is made for the following methods:a. RORAI method
b. AWC method
c. PW method
Upload the picture of your complete solutions including the correct cash flow diagram (for plus points) and your conclusion.
You are faced with a decision on an investment proposal. Specifically, the estimated additional income from the investment is $125,000 per year; the investment cost is $400,000; and the first year estimated expense of $20,000 and will increase a rate of 5% per year. Assume an 8-year analysis period, no salvage value, and MARR = 15% per year.
a. Calculate the PW and FW of this proposal?
b. What is the ERR ( Ԑ=MARR) of this proposal?
c. What is the Simple and Discounted payback?

- Dupont is considering licensing a low liquid discharge (LLD) water treatment system from a small company that developed the process and owns the license. Dupont can purchase a 1-year option for $100,000 that will provide time to pilot test the LLD process or Dupont can acquire the license now at a cost of $1.8 million plus 25% of sales paid annually to the license owner. If they wait 1 year, the cost will increase to $1.9 million plus 30% of sales paid annually. If sales are estimated to be $1,000,000 per year over the 5-year license period, should Dupont purchase the license now or purchase the option now and possibly license it after the 1-year test period?
