摘要:

In practice, engineering economic analysis involves uncertainty about future cash flows. To deal quantitatively with imprecision or uncertainty, fuzzy set theory is primarily concerned with vagueness in human thoughts and perceptions. As an alternative to conventional cash flow models where cash flows are defined as either crisp numbers or risky probability distributions, we propose an engineering economic decision model in which the uncertain cash flows and discount rates are specified as triangular fuzzy numbers. The present worth formulation of this fuzzy cash flow model is derived. The result of the present worth is also a fuzzy number with nonlinear membership function. The present worth can be approximated by a triangular fuzzy number. Deviation between exact present worth and its approximate form is examined. Finally, the fuzzy project selection is performed by applying different dominance rules. To demonstrate the application of the fuzzy present worth function, a comprehensive numerical example is presented.

摘要:

This paper compares and contrasts several previously proposed rate of return capital budgeting methodologies. It focuses on recently proposed overall rate of return methods that provide NPV-consisient project evaluations. The examination is undertaken by introducing a conceptual framework to characterize rate of return methods along the following three parameters: (1) the investment base, (2) the reinvestment rate, and (3) the lime horizon over which projects are evaluated. This parametric framework highlights differences among alternative rate of return methods so that they can be easily compared and contrasted. Additionally, the examination suggests appropriate potential applications for the alternative methodologies.

摘要:

Computer codes for the routine implementation of tbe Teichroew-Robicheck-Montalbano (TRM) rate-of-return formulation are presented. Project cash flow sequences are classified as one of the four TRM cases and then analyzed. Project investment rates (PIR) are calculated for user specified minimum attractive rates of return.

摘要:

Recently, Formato derived a useful formula of the amount of periodic equal payment in a skip payment loan with arbitrary skips using a second-order finite difference equation. We rederive his formula using simple arithmetics and provide an intuitive explanation of the formula. We also extend his result to the case that periodic payments occur in a geometric-gradient-series.
