Definition of Engineering Economy
Engineering the profession in which a knowledge of the
mathematical and natural sciences gained by study, experience and practice is applied with judgment to develop ways to utilize, economically, the materials and forces of nature for the benefit of mankind
Engineering Economy systematic evaluation of the economic
merits of proposed solutions to engineering problems

Principles of Engineering Economy
1 Develop the alternatives The choice is among the alternatives. The
alternatives need to be identified and defined for subsequent analysis.
2 Focus on the Differences Only the differences in expected future
outcomes among the alternatives are relevant to their comparison and should be considered in the decision.

3 Use a Consistent Viewpoint The prospective outcomes of the
alternatives, economic and other, should be consistently developed from a defined viewpoint or perspective.
4 Use a Common Unit of Measure Using a common unit of measurement to
enumerate as many of the prospective outcomes as possible will simplify the analysis and comparison of the alternatives.

5 Consider All Relevant Criteria Selection of a preferred alternative requires
the use of a criterion or several criteria. The decision process should consider both the outcomes enumerated in the monetary unit and those expressed in some other unit of measurement or made explicit in a descriptive nature.

6 Make Uncertainty Explicit Uncertainty is inherent in projecting the
future outcomes of the alternatives and should be recognized in their analysis and comparison.
7 Revisit Your Decisions Improved decision making results from an
adaptive process; to the extent practicable, the initial projected outcomes of the selected alternatives should be subsequently compared with actual results achieved. 8
