Question

Engineering Economy problem.

Please, when answering this problem, it will be more than appreciated if you can present clearly the analysis, in order to learn and understand it. Example: Present Value = 20,000(P/F, i, n)+45,000(A/F, i, n)(P/F, i, n)... Thanks in advance!

There are two manufacturing processes that can be used by a company to reduce energy losses in the equipment’s. The following cost information for these two processes is known:

By doing the following analysis, select which manufacturing process must be selected (A or B):

a) Find the Present Value for Process A and for Process B, with an interest rate of 12% annually computed quarterly

b) Find the Quarterly equivalent uniform value for Process A and for Process B with an interest rate of 8% annually computed quarterly

c) Find the Capitalized Cost for Process A and for Process B with an interest rate of 14% annually computed quarterly

Process A Process B Initial Cost $170,000 $220,000 Operation and Maintenance Cost $7,000 quarterly $5,000 quarterly Useful Life (Life Cycle) 2 years 4 years Residual Value $30,000 $42,000

Explanation / Answer

(a) 14% annual rate = 12/4 = 3% quarterly rate

PROCESS - A

Present Value, PV = $170,000 + $7,000 x P/A (3%, 8) - $30,000 x P/F (3%, 8)

= $170,000 + ($7,000 x 7.02) - ($30,000 x 0.79)

= $(170,000 + 49,140 - 23,700) = $195,440

PROCESS - B

Present Value, PV = $220,000 + $5,000 x P/A (3%, 16) - $42,000 x P/F (3%, 16)

= $170,000 + ($5,000 x 12.6) - ($42,000 x 0.62)

= $(170,000 + 63,000 - 26,040) = $206,960

(b) 8% annual interest rate = 2% quarterly rate

Process A = $170,000 x A/P (2%, 8) + $7,000 - $30,000 x A/F (2%, 8)

= $170,000 x 0.14 + $7,000 - $30,000 x 0.12

= $(23,800 + 7,000 - 3,600) = $27,200

Process B = $220,000 x A/P (2%, 16) + $5,000 - $42,000 x A/F (2%, 16)

= $220,000 x 0.0737 + $5,000 - $42,000 x 0.0537

= $(16,214 + 5,000 - 2,254) = $18,960
