Engineering economics is one of the most practical subject matters in the engineering curriculum, but it is an always challenging, ever-changing discipline. Contemporary Engineering Economics ( CEE ), now in its fi fth edition, was fi rst published in 1993, and since then, we have tried to refl ect changes in the business world in each new edition along with the latest innovations in education and publishing. These changes have resulted in a better, more complete textbook, but one that is much longer than it was originally intended. This may present a problem: Today, covering the textbook in a single term is increasingly diffi cult. Therefore, we decided to create Fundamentals of Engineering Economics ( FEE ) for those who like contemporary but think a smaller, more concise textbook would better serve their needs.
