Providing a New Approach in Engineering Economics

Engineering economy set of mathematical techniques for economic evaluation of investment projects that present value and internal rate of return method are among the most important of these methods. Managers and investors have many reasons to using internal rate of return greater willingness shown. This is while the serious problems associated with using internal rate of return method. In recent years, several articles have been published in order to fix the way in which we can approach the Magni in 2010. The aim of this paper is to simplify and facilitate the model is, in other words, by eliminating some of the most simple and straightforward algorithm to calculate the rate of return Magni way we present period.
