This ninth edition of Engineering Economy emphasizes that the essential prerequisite of successful engineering application is economic feasibility. We present the concepts and technique of analysis useful in evaluating the economic feasibility of systems, products, and services. Our Objective is to help the reader understand the significance of the economic aspects of engineering and to become proficient in the evaluation of engineering proposals in terms of worth and cost.
