Wind energy has been operating in Poland for over 20 years, but many opinions on its profitability are based publications from other countries and simulations prepared by manufacturers. However, the truth is that climatic specificity of various price relationships, especially prices subsidies, significantly differentiate this depending country. The publication aimed to look at wind farms three ...

• Techno-economic assessment of subcritical water and ethanol extraction (SWE EE) Both SWE EE are at high maturity stage (TRL-9) in industrial setting. had lower cost manufacturing (COM) than for same baseline throughput. Increasing raw materials increased COM both EE. Net Present Value (NPV) was double NPV The techno-economic feasibility (TEA), technology readiness level (TRL), environmental i...

Open-Pit Production Scheduling (OPPS) problem focuses on determining a block sequencing and scheduling to maximize Net Present Value (NPV) of the venture under constraints. The scheduling model is critically sensitive to the economic value volatility of block, block weight, and operational capacity. In order to deal with the OPPS uncertainties, various approaches can be recommended. Robust opti...

While a great portion of the scheduling literature focuses on time-based criteria, the most important goal of management is maximizing the profitability of the firm. In this paper, the net preset value criterion is studied taking account of linear time-dependent cash flows in single machine and flow shop scheduling problems. First, a heuristic method is presented for the single machine scheduli...

this paper presents a comprehensive theoretical, experimental, and economic study on the application of nanofluids as heat transfer fluid in waste heat recovery systems. the research work was conducted in a steel-making complex in which a plate heat exchanger had been used to recover heat from hot process water. the system was theoretically modelled and the effects of using nanofluids as heat t...

This article discusses how to quantify the forecasting quality of IT business value. We address a common economic indicator often used to determine the business value of project proposals, the Net Present Value (NPV). To quantify the forecasting quality of IT business value, we develop a generalized method that is able to account for asymptotic cases and negative valued entities. We assess the ...
