11. Selecting among alternatives: Useful lives are unequal among alternatives
In this video, I explain Selecting Among Alternatives When Useful Lives Are Unequal as an important topic in Engineering Economics.
The lecture focuses on how to compare engineering alternatives when their useful lives differ, including cases where the useful life is longer than the study period and when it is shorter than the study period.
You will learn how to properly adjust cash flows using the concepts of repeatability (replacement chain) and co-terminated (study period) analysis, and when each approach should be applied.
The video also covers the concept of Imputed Market Value, explaining how to estimate and use it when an alternative’s useful life exceeds the analysis period to ensure fair economic comparison.
These methods are essential for accurate decision-making in projects involving equipment selection, replacement analysis, and long-term investment planning.
This video is intended for students studying Engineering Economics, Industrial Engineering, Mechanical Engineering, and Management Engineering.
