Is the design/device technically feasible? What does it cost/will it pay for itself? Practicing engineers are routinely faced with these crucially important questions. To answer the first question, engineers draw upon their technical skills, which have been carefully honed through courses in engineering science/design as well as by professional experience. The second question is often more difficult for engineers to answer affirmatively. This may be true because economic principles were addressed only as an afterthought in their engineering coursework, or possibly not at all! Those students who were fortunate enough to have taken a course in engineering economy have little difficulty answering the 'Will it pay...?' question, which is frequently just as important a question as 'Will it work?' This statement strikes many engineering students as unbelievable; yet later on, their professional careers will be significantly affected by their ability to deal competently with the economic aspects of engineering.
This twelfth edition of Engineering Economy provides exciting insights and thought-provoking inquiries into the principles, concepts, and techniques of engineering economy. The primary audience for this text is undergraduate students in engineering. As in previous editions, the twelfth edition reflects current theory and practice in the file of engineering economy by way of comprehensive and lucid content. In this edition an attempt has been made to demonstrate how the analysis of alternatives and the ability to earn an adequate return on capital investments are related to the well-being of flourishing and profitable enterprises.
