Textbook Question
Chapter 6, Problem 45P
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.
- a. Which alternative is preferred, based on the repeatability assumption? (6.5)
- b. Show, for the coterminated assumption with a five-year study period and an imputed market value for Alternative B, that the AW of B remains the same as it was in Part (a). [And obviously, the selection is the same as in Part (a).] Explain why that occurs in this problem. (6.5)

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
It is estimated that an investment alternative with an
initial investment cost of 150000 TL will generate
annual revenues of 85000 TL and annual expenses of
20000 TL. It is expected to have a scrap value of 95000
TL at the end of its 5-year life. Find out how sensitive
the investment decision of this investment alternative
is to its revenues. (MARR: %10)
An agricultural land requires a 20PK motor to pump water from a water sources. The number of operating hours (motor hours) each year depends on height rainfall, so the hours of operation are variable. The motor is used in the long term 4 years time. There are 2 alternatives proposed for the procurement of these motors:Alternative A:The cost of buying an automatic electric motorbike is Rp. 1,400 million with a final value of Rp. 200 million With a lifespan of 4 years. Operational costs of Rp. 840k per hour, and maintenance fee of Rp. 120 million per year.
Alternative B :The cost of purchasing a gasoline motorbike is Rp. 550 million with a final value of zero. With age used for 4 years.Operational costs consist of:• Gasoline costs Rp. 420k per hour• Maintenance fee of Rp. 150k per hour• Operator fee Rp. 800k per hourQuestion :Determine in how many hours each year the two motors must operate, in order to cost the two alternatives are equal. Use MARR 10% per year. When used during 1,000…
