Single-Valued Neutrosophic SWARA-TOPSIS-Based Group Decision-Making for Prioritizing Renewable Energy Systems

Abstract

In this paper, new outcomes on the evaluation of sustainability factors for Renewable Energy Sources (RESs) under Single Valued Neutrosophic Sets (SVNSs). Multiple Criteria Decision-Making (MCDM) model and the SVN-Stepwise Weight Assessment Ratio Analysis (SWARA) with SVN-Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) termed as ‘SVN-SWARA-TOPSIS’ are applied to solve the RESs selection problem. Five sustainability indicators RSTEE (resource, social, technology, environmental and economic) and twelve criteria are considered for RESs selection. In the proposed SVN-SWARA-TOPSIS method, three decision experts are selected for assessing the sustainability factors to the evaluation of RESs. In the developed framework, weight of the assessment of sustainability criteria are estimated by SVN-SWARA approach and preference order of RES options is determined by SVN-TOPSIS method on SVNSs setting. Finally, comparative and sensitivity assessments are discussed to analyse the validity of obtained result.
