Abstract Wind energy has become one of the main sources green having reached a peak 220 GW installed wind capacity in 2020 European Union according to TPA report (2021). With expansion installments, project management field also had numerous challenges terms estimating projects worth implementing capital and operating costs, as well benefits. The present article presents method evaluating proje...

The publication of ISO 15686-5 is significant for studies related to the life-cycle costs buildings. Among many economic evaluation methods, NPV method recommended use by this standard. This study explains concept and PV, then provides an explanation NPV, points out limitations in practical application method.

Patients who have undergone angioplasty experience difficulty modifying at-risk behaviors for subsequent cardiac events. The purpose of this study was to test whether an innovative approach to framing of risk, based on 'net present value' economic theory, would be more effective in behavioral intervention than the standard 'future value approach' in reducing cardiovascular morbidity and mortali...

The history of polio vaccination in the United States spans 50 years and includes different phases of the disease, multiple vaccines, and a sustained significant commitment of resources. We estimated cost-effectiveness ratios and assessed the net benefits of polio vaccination applicable at various points in time from the societal perspective and we discounted these back to appropriate points in...

    Project scheduling   Net present value   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 or more sub-projects including activities interrelated by finish-start-type precedence relations with a t...

This research models the development decision when net rents are growing geometrically and uncertainly, and capital intensity is variable. We derive simple rules for the optimal timing of land development projects based on the commonly used internal rate of return and net present value criteria. We show that, even under certainty, projects are optimally delayed beyond the point where net presen...

distinguishing productive zones of a drilled oil well plays a very important role for petroleum engineers to decide where to perforate to produce oil. conventionally, net pay zones are determined by applying a set of cut-offs on perophysical logs. as a result, the conventional method finds productive intervals crisply. in this investigation, a net index value is proposed, then; diffusivity equa...
