- Overview

Fundamentally, engineering economics involves formulating, estimating, and evaluating economic outcomes when alternatives to achieving a stated purpose are available.

Engineering economics, formerly known as engineering economics, is a subset of economics that involves the use and application of principles of economics in engineering decision analysis. 

As a discipline, it focuses on a branch of economics known as microeconomics because it studies the behavior of individuals and companies when making decisions about the allocation of limited resources. 

Therefore, it focuses on the decision-making process, its context and environment. It is pragmatic in nature, combining economic theory with engineering practice. However, it is also a simplified application of microeconomic theory, as it assumes that factors such as price determination, competition, and demand/supply are fixed inputs from other sources.

However, as a discipline, it is closely related to other disciplines such as statistics, mathematics and cost accounting. It draws on the logical framework of economics, but adds the analytical power of mathematics and statistics.


- The Four Fundamentals of Engineering Economics

  • Principle 1: A dollar earned today is worth more than a dollar earned in the future. 
  • Principle 2: The only thing that matters is the difference between alternatives. 
  • Principle 3: Marginal revenue must exceed marginal cost. 
  • Principle 4: Additional risk is not taken without the expected additional return.
