Engineering Economy - Applying Theory to Practice by Ted G. Eschenbach

By Ted G. Eschenbach

This completely revised moment version combines real-world difficulties, mini-cases, and examples with an excellent theoretical beginning in engineering economic system. The booklet covers the entire ordinary issues integrated within the basics of Engineering (FE) examination. It essentially illustrates suggestions and methods-such as fee estimating, sensitivity research, likelihood, and a number of objectives-needed for winning software of engineering financial system in perform. additionally, absolutely built-in ExcelRG spreadsheets through the textual content, functionality as fundamental analytical instruments for problem-solving and realizing.

Sample text

Because engineering economy focuses on the future consequences of current decisions, much of the data analyzed are estimates rather than exact quantities. Thus, the uncertainty in these estimates should be explicitly addressed. Chapters 17 and 18 on sensitivity and probability analyses present the tools to do this. 3 THE DECISION-MAKING PROCESS The real world contains messes [Ackoff], not problems. A chaotic conglomeration of conflicting objectives, undefined constraints, and incomplete or contradictory data is a mess, not a problem.

These seven steps provide a logical framework for making engineering economy decisions and solving other problems. Chapter problems will focus on the economic evaluation of alternatives, but the real world requires that you deal with the entire decision-making process. Hammond (1999) details a similar process for making good decisions. 3 is useful as a guide. However, effective real-world decision making must modify it and consider other factors. This section clarifies how decisions are and should be made: • • • • • • Nonlinear process has feedback loops and simultaneous activities.

These include documenting: (1) which alternatives were considered and rejected, (2) data sources, and (3) assumptions. Analysis uses resources of time, people, and money. Action produces results. Analysis vs. Action. 6, instructors and students are often concerned with the quality of analysis. Firms and agencies are concerned with the benefits of action. Once an alternative has been identified as the best, then the cost of delay and further analysis usually exceeds the expected improvement in results.
