Abstract
The study performs multi-dimensional decision-making using the Evaluation of Distance from Average Solution (EDAS) with improved entropy weighting applied to figure out the best configuration for the ORC-VCR arrangement from a thermo-economic and environmental perspective. It is intended to maintain the operation of ORC-VCR’s complete energy efficiency alongside producing minimal environmental impact. Besides EDAS, grey relational analysis has been conducted for an effective and precise determination of non-naïve operation controls. Moreover, objectively a novel cross-judgemental analysis has been implemented to measure the difference in opinion (DIO) between grey relational analysis and EDAS. The study has concluded in 30 % improvement in the desirability score of optimal operational setting for the ORC-VCR arrangement through EDAS. Judgemental analysis has proved the significance of EDAS from the perspective of a popular method like grey relational analysis, projecting a < 10 % DIO.
