- The Siler Construction Company is about to bid on a new industrial construction project. To formulate their bid, the company needs to estimate the time required for the project. Based on past experience, management expects that the project will require at least 24 months, and could take as long as 48 months if there are complications. The most likely scenario is that the project will require 30 months. a. Assume that the actual time for the project can be approximated using a triangular probability distribution. What is the probability that the project will take less than 30 months? b. What is the probability that the project will take between 28 and 32 months? c. To submit a competitive bid, the company believes that if the project takes more than 36 months, then the company will lose money on the project. Management does not want to bid on the project if there is greater than a 25% chance that they will lose money on this project. Should the company bid on this project?arrow_forwardAssume the cost of homeland security border fence is $3 million per mile.

- I have two projects that I am evaluating: project A, where the initial investment is 5,000TL and the annual return is 5,000TL, and project B where the initial investment is 8,000TL and annual return is 6,000TL. Both projects are for 5 years. I have done my calculations and I cannot select between these two. What is my MARR?

One million pallets will be handled by the palletizer each year during the seven-year expected project life.

- Suppose the MARR is 10% with probability 0.25, 12% with probability 0.50, and 15% with probability 0.25; what is the probability that Alternative A is the most economic alternative? Two investment alternatives are being considered. Alternative A requires an initial investment of $15,000 in equipment; annual operating and maintenance costs are anticipated to be normally distributed, with a mean of $5,000 and a standard deviation of $500; the terminal salvage value at the end of the 8-year planning horizon is anticipated to be normally distributed, with a mean of $2,000 and a standard deviation of $800. Alternative B requires endof-year annual expenditures over the planning horizon. The annual expenditure will be normally distributed, with a mean of $8,000 and a standard deviation of $750. Using a MARR of 15%, what is the probability that Alternative A is the most economic alternative?arrow_forwardA project in Guatemala has initial costs of $25 million, but is expected to have a low salvage value.

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 ( E=MARR) of this proposal? c.
