Understanding Engineering Economy
Engineering economy is a branch of economics that focuses on the evaluation and comparison of engineering alternatives in terms of their economic viability. It provides the tools necessary for making informed decisions regarding investments in projects, equipment, and infrastructure. Key concepts in engineering economy include:
- Time Value of Money: The principle that money available today is worth more than the same amount in the future due to its potential earning capacity.
- Cost-Benefit Analysis: A systematic approach to estimating the strengths and weaknesses of alternatives in order to determine the best option.
- Investment Appraisal: Techniques used to assess the profitability and financial viability of proposed investments.
