Three mutually exclusive design alternatives are being considered. The estimated sales and cost data for each alternative are given in Table 1. The MARR is 20% per year. Annual revenues are based on the number of units sold and the selling price. Annual expenses are based on fixed and variable costs. Determine which selection is preferable based on AW. Assume all units are produced and sold each year.

An industrial park is being planned near a river. The river occasionally floods, and as a result theindustrial park planners are trying to decide how large of an embankment to build as protection. Theembankment is expected to last 50 years. The MARR is 12%. If the water rises above theembankment (regardless how much) and flooding occurs, the cost is $300,000. Using the data below,find the expected annual costs in each case and determine which embankment height should beselected.Embankmentheight(meters)Initial Costof EmbankmentProbability of water rising aboveembankment in any given year2.0 $100,000 0.3302.5 $165,000 0.1253.0 $300,000 0.0403.5 $400,000 0.0204.0 $550,000 0.01 Please attach an actual excel file too.
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
The MARR is 7% per year, capital investment is $118,894, annual expense is $32,856, annual revenue is $60,700, market value at the end of useful life is $11,768. The useful life is 8 years. Use the contaminated assumption. The study period is 5 years. What is the FW?
Engineering Economics Bawal gumamit ng excel( Don't use Excel) A small company has P20,000 in surplus capital that it wishes to invest in new revenue producing projects. Three independent sets of mutually exclusive projects have been developed. The useful life of each is five years and all market values are zero. You have been asked to perform an IRR analysis to select the best combination of projects. If the MARR is 12% per year, which combination of projects would you recommend?
The PW of five independent projects have been calculated at an MARR of 12% per year. Select the best combination at a capital investment limit of (a) $25,000, (b) $49,000, and (c) unlimited.

A company purchases a new filtration system by borrowing the $30,000 purchase price. The loan is to be repaid with 4 equal annual payments at an annual compound rate of 12%. It is anticipated that the system will be used for 9 years and then be sold for $2,000. Annual operating and maintenance expenses are estimated to be $9,000/year. A savings of $15,000/year is realized over the present system. The firm uses a MARR of 15% for its economic analyses. Determine PW, AW and FW.
Two designs are suitable for housing track and field events. Design N costs $800,000 with annual upkeep costs including maintenance, repair, heat, and janitor service, of $25,000 a year. Its life is expected to be permanent. Design T costs $450,000 with annual upkeep costs for the previous items of $35,000 a year. However, with this design, repairs costing $15,000 will be required every 5 years, and the life will be 25 years with a probable salvage at that date of $50,000. The minimum required rate of return is 10%. Use present worth analysis to compare these two alternatives.
The owner of a downtown parking lot has employed a civil engineering consultingfirm to advise her on the economic feasibility of constructing an office building onthe site. The project engineer has assembled the following data: The analysis period is to be 15 years. At the end of that time the salvage value is expected to be equal to the initial investment.MARR is 10%. What should the engineer recommend?

A piece of production equipment is to be replaced immediately because it no longer meets quality requirements for the end product. The two best alternatives are a used piece of equipment (E1) and a new automated model (E2). The economic estimates for each are shown in the accompanying table. The MARR is 15% per year. Which alternative is preferred based on the: (c) repeatability assumption. Use FW method. FW (E1) = $_____? FW (E2) = $_____? The best alternative is E_____?

Standby power for pumps at water distribution booster stations can be provided by either gasolineor diesel-powered engines. The estimates for the gasoline engines are as follows: Gasoline First cost, $ −150,000 M&O, $ per year −41,000 Salvage value, $ 23,000 Life, years 15 If the incremental PW-based ROR equation associated with (Diesel – Gasoline) is 0 = – 40,000 + 11,000(P∕A,Δi*,15) + 16,000(P∕F,Δi*,15), the first cost of the diesel engine is closest to: (a) –190,000 (b) –110,000 (c) –60,000 (d) – 40,000
