The change in the amount of money over a given time period is called the time value of money; it is the most important concept in engineering economy. The time value of money can be taken into account by several methods in an economy study, as we will learn.
The engineering economics is concerned the systematic evaluation of the benefits and costs of projects involving engineering design and analysis. Engineering economics quantifies the benefits and costs associating with engineering projects to determine if they save enough money to warrant their capital investments.
Fundamentally, engineering economics involves formulating, estimating, and evaluating the economic outcomes when alternatives to accomplish a defined purpose are available. In some U.S. undergraduate civil engineering curricula, engineering economics is a required course.
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.
As a subdiscipline practiced by civil engineers, engineering economics narrows the definition of the fundamental economic problem and related questions to that of problems related to the investment of capital, public or private in a broad array of infrastructure projects.
Economics and the world Economics helps us understand the world around us and how it really works. It also helps us to understand people, governments, businesses and markets and why they make the economic choices they do.Jun 30, 2021
Scarcity explains the basic economic problem that the world has limited—or scarce—resources to meet seemingly unlimited wants. This reality forces people to make decisions about how to allocate resources in the most efficient way possible so that as many of their highest priorities as possible are met.

1.3 Performing an Engineering Economy Study An engineering economy study involves many elements: problem identification, definition of the objective, cash flow estimation, financial analysis, and decision making. Implementing a structured procedure is the best approach to select the best solution to the problem.
