Engineering economics, previously known as engineering economy, is a subset of economics concerned with the use and "application of economic principles" in the analysis of engineering decisions. As a discipline, it is focused on the branch of economics known as microeconomics in that it studies the behavior of individuals and firms in making decisions regarding the allocation of limited resources. Thus, it focuses on the decision-making process, its context and the environment

As a discipline though, it is closely related to others such as statistics, mathematics, and cost accounting. It draws upon the logical framework of economics but adds to that the analytical power of mathematics and statistics

Engineers seek solutions to problems, and along with the technical aspects, the economic viability of each potential solution is normally considered from a specific viewpoint that reflects its economic utility to a constituency. Fundamentally, engineering economics involves formulating, estimating, and evaluating the economic outcomes when alternatives to accomplish a defined purpose are available.

Since engineering is an important part of the manufacturing sector of the economy, engineering industrial economics is an important part of industrial or business economics. For this reason, the major courses that are covered in this course are:

• The economics of the management, operation, and growth and profitability of engineering firms;

• Macro-level engineering economic trends and issues;

• Engineering product markets and demand influences; and

• The development, marketing, and financing of new engineering technologies and products.

This Course Includes the following topics.

• Introduction: Engineering economy defined, measures of financial effectiveness, non-monetary factors and multiple objectives. Principles of engineering economy.

• The Economic Environment: Consumer and producer goods, measures of economic worth. price, supply, & demand relationship. production. factors of production laws of return.

• Cost Concepts & Analysis: Sunk & opportunity costs. fixed, variable, and incremental costs, recurring & nonrecurring costs. direct, indirect. and overhead costs, standard costs. Break-even analysis, unit cost of production, cost-benefit analysis, feasibility studies, value analysis in designing & purchasing.

• Time Value of Money: Simple interest, compound interest, cash flow diagrams, interest formulas, nominal versus effective interest rate, continuous compounding.

• Depreciation and Depletion: Purpose of depreciation, types of depreciation, economic life and what can be depreciated?

• Comparing Alternatives: Present economy, selection among machines, materials, processes, and designs, payback period method, present worth method, uniform annual cost method, rate of return method, alternatives having identical lives, alternatives having different lives.

• Linear Programming: Mathematical statement of linear programming problems graphic solution. Simplex method and duality problems.
