Huston University of Cincinnati Cincinnati Ohio INTRODUCTION Engineering is the profession that is devoted to the application of scientific knowledge for practical purposes. Through the application of scientific knowledge engineers are continually developing products processes and services for the benefit of society. Engineers have been instrumental in many of the advances of society. For example the state of modern transportation can be linked to the efforts of engineers. While undertaking such pursuits the engineer is typically faced with a variety of alternatives. These alternatives may include material selections the degree of computer automation the selection of an applicable safety system and the means of manufacturing. Each alternative will have inherent technical advantages and disadvantages that the engineer must evaluate. The evaluation of any alternative will also have to consider the constraints of the particular problem or project. The engineer will typically be well informed about the technical aspects of various alternatives. However the engineer must also have a sound understanding of the economic feasibility of the various alternatives. Indeed money is a scarce resource that must be allocated in a prudent fashion. This chapter provides a foundation in the basic principles of engineering economics. Through the application of these basic principles the engineer will be able to address economic issues. One such issue is the economic feasibility of alternatives. Engineering economics offers a means to assess any receipts and disbursements associated with an alternative. Such an assessment will consider the magnitude and timing of the receipts and disbursements. Inflation and taxes may also be factors that enter into the economic evaluation of an alternative. The basic principles of engineering economics also provide methods for the comparison of alternatives and the subsequent selection of an optimal .
