Sensitivity Analysis of Investment in a Surface-mount Placement Machine
We are considering investing in a surface-mount placement (SMP) machine: a $480,000 initial
investment, annual savings of $92,500 for a 10-year period, and a salvage value of $46,000.
Assume a MARR of 10% per year.
Determine how sensitive the annual worth (AW) for the investment is to errors in estimating the
initial investment, the annual savings, the salvage value, and the MARR. Specifically, for an
error range of ± 50% for each parameter, what is the impact on AW?
