ENGINEERING ECONOMICS subset of economics for application to engineering projects.
Engineering economics is a challenging subject as it requires some level of technical expertise in engineering.
For economics students solving engineering economics assignments
problems often gets troublesome and they end up either doing them wrong
or seeking help from companies that charge them exorbitantly high
Engineering economics, earlier known as engineering economy
Is a subset of economics for application to engineering projects. Engineers look for solutions to problems, and the feasibility on the economic front of each possible solution is normally weighed along with the technical aspects.
In the curriculum of some U.S. programs, engineering economics is often a necessary course. It is a topic dwelling upon the Fundamentals of Engineering examination, and questions might also be framed on the Principles and Practice of Engineering examination; both are part of the Professional Engineering registration process.
Considering the time value of money is vital to most engineering economic analyses. Cash flows are discounted using an interest rate, I except in the most basic economic studies.
For every problem,
there are generally quite a few possible alternative solutions. One alternative that must be considered in each analysis, and is often the adopted choice, is the option of doing nothing.
The opportunity cost of making one choice in preference to another must also be considered. There are also noneconomic factors to be considered, like colour, style, public image, etc.; such factors are termed attributes.
Costs as well as revenues are to be considered, for each option, for an analysis period that is either a fixed number
of years or the projected life of the project. The salvage value is often forgotten, but is vital, and is either the net
cost or revenue for decommissioning the project.
Some other topics that may be considered in engineering economics are
inflation uncertainty replacements depreciation Resource depletion
taxes tax credits accounting cost estimations or capital financing
All these topics are the most important skills and primary knowledge areas in the field of cost engineering.
Since engineering is a vital part of the manufacturing sector of
the economy, engineering industrial economics is a pivotal part of industrial or business economics.
Major topics in engineering industrial economics 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 product.
