Question

Four mutually exclusive service alternatives are
under consideration for automating a manufacturing
operation. The alternatives were ranked in
order of increasing initial investment and then
compared by incremental rate of return analysis. The rate of return on each increment of investment
was less than the MARR. Which alternative should
be selected?

Expert Solution
Step 1

For mutually exclusive services, an alternative is selected on the following basis:

  • Increment on capital is justified itself on a rate of return equal to or greater than MARR.
  • An alternative with higher investment is compared with alternative of lower investment. The difference between the investments of the alternatives is termed as investment alternative.
