This book is intended for undergraduate engineering students taking the introductory engineering economics course at the university level. The third edition of Contemporary Engineering Economics has been thoroughly revised and updated while continuing to adopt a contemporary approach to the subject, and teaching, of engineering economics. This text aims not only to build a sound and comprehensive coverage of engineering economics, but also to address key educational challenges, such as student difficulty in developing the analytical skills required to make informed financial decisions.

Preface What is "Contemporary" About Engineering Economics? Decisions made during the engineering design phase of product development determine the majority of the costs of manufacturing that product (some say 85%). As design and manufacturing processes become more complex, the engineer is making decisions that involve money more than ever before. Thus, the competent and successful engineer in the twenty-first century must have an improved understanding of the principles of science, engineering, and economics, coupled with relevant design experience. Increasingly, in the new world economy, successful businesses will rely on engineers with such expertise. Economic and design issues are inextricably linked in the product/service life cycle. Therefore, one of my strongest motivations for writing this text was to bring the realities of economics and engineering design into the classroom and to help students integrate these issues when contemplating many engineering decisions. With the advent of information technology, the Internet becomes an indispensable tool in exchanging information. Accordingly, we have developed a comprehensive companion website to the book to provide numerous teaching and learning aids. I believe that our website is a critical resource for transitioning the teaching of engineering economy into the twenty-first century. Of course my underlying motivation for writing this book was not simply to address contemporary needs, but to address as well the ageless goal of all educators: to help students to learn. Thus, thoroughness, clarity, and accuracy of presentation of essential engineering economics was my aim at every stage in the development of the text. Changes in the Third Edition In the complex and changing world of a global economy in an age of information, the practice of engineering economics is dynamic and as new developments occur, they should be incorporated into a textbook such as this one. In addition, the author and publisher are constantly seeking ways of improving the book in terms of clarity and understanding. As a result, we have made several important changes in this edition, including the following: The overall book design style has been changed. The new design format allows us to use a second color more effectively to highlight the most important information and separate examples from the main text reading, providing an effective study and review tool for students. There are 17 chapters, including three new chapters. Each chapter is classified into one of five parts: Part I: Financial and Cost Information; Part II: Money and Investing; Part III: Evaluating Business and Engineering Assets; Part IV: Development of Project Cash Flows; and Part V: Special Topics in Engineering Economics. All sections were updated to reflect the latest tax laws, interest rates, and other financial developments. A discussion on end-of-chapter "Computer Notes" is consolidated into the website for Contemporary Engineering Economics: http://www.prenhall.com/parkorhttp://www.eng.auburn.edu/~Park/cee.html This allows us to remove all Microsoft Excel spreadsheet discussions from the main text. Now students can download various spreadsheet templates from the website and open directly in Excel for Windows. The obvious benefit is that it is no longer necessary to enter the spreadsheets by hand. Users can then modify the basic templates for the specific problem at hand. About one third of examples and self-test questions in the main chapters are either new or revised ones to reflect the contemporary nature of economic decision problems. In Chapters 9 and 14, some of the advanced topics (or optional materials) such as the multiple-rates of return problems and risk simulation have been removed from the main text and placed in the Appendix.
