Projects may be evaluated and compared according to the Net Present Value (NPV) of their cash flow. The NPV is the discounted expected revenues minus the costs over the lifetime of the project. Traditional NPV calculations do not take into account the uncertainty in the variables that influence the revenues and costs. We present a simulation approach to incorporate uncertainty in the NPV calcul...

Projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. An integer programming model is formulated for the project portfolio selection and scheduling.Two heuristic algorithms, genetic algorithm (GA) and simulated annealing (SA), are presented to solve the problem. Results of cal...

this study highlights the costs and benefits of indigenous beef cattle fattening schemes in shinyanga urban and kishapu districts in tanzania. specifically, in this study the net profit (np) for fatteners between beef cattle fattening schemes has been determined. the schemes were divided into two main categories, scheme 1 in which the animals were fed on cottonseed hulls (cshl) based diets and ...

In this paper we conjugate the operative usability of the net present value with the capability of the fuzzy and the interval approaches to manage uncertainty. Our fuzzy interval net present value can be interpreted, besides the usual present value of an investment project, as the present value of a contract in which the buyer lets the counterpart the possibility to release goods/services for m...

For one–period projects under certainty, the notion of Net Present Value (NPV) formally translates the notion of economic profit, where the discount rate is the cost of capital. Under uncertainty, the cost of capital is the expected rate of return of an equivalent-risk alternative that the investor might undertake and is often found by making recourse to the Capital Asset Pricing Model. This pa...
