We consider a project scheduling problem with permitted tardiness and discrete time/resource trade-offs under maximum net present value objective. In this problem, a project consists of a set of sequential phases such that each phase contains one...

In this paper, we address a new problem in the context of project payment scheduling when project activities are allowed to be crashed with the purpose of maximizing the contractors net present value

(NPV). We assume that the contractor...

, and is based on two models, conventional and organic. The objective of the model is to maximize the net present value over a 10-year planning horiz on. The data for analysis has collected from the Agricultural Research Organization of Mazandaran province in 201...

Nowadays installed power capacity of grid-connected photovoltaic (GCPV) systems has an exponential

increase around the world. Since these systems are more expensive than other conventional electricity

resources, ...

for solar inverter and panel, respectively. The analysis is accomplished by determining the economic parameters, including net present value (NPV),

internal rate of return (IRR), and payback period time (PBT) for all PV structures with the same...

The objectives of this research were to determine the impacts of irrigated wheat breeding in reducing costs, Net Present Value (NPV), Cost-Benefit Analysis (CBA) and Internal Rate of Return (IRR) for Mehregan, Shush, Baharan and Narin bread wheat...

in Iran is carried out. Several economic indices, including net present value (NPV), internal rate of return (IRR), benefit-cost ratio (BCR), payback period time (PBT), and levelized cost of energy (LCOE) are determined to unveil the effectiveness...

in developing countries with predominantly imported equipment and unstable economic

conditions. The new policy is described, and the economic perspective is cleared by computing the economic indices, including net present value (NPV), internal rate...
