Applications of VIKOR Method in Supplier Selection: A Meta-Regression Analysis

OpenAlex İngilizce

Purpose -This study attempts to systematically analyze empirical studies using VIKOR method in solving supplier selection problem and to identify the factors affecting mean S (MS) scores through use of meta-regression analysis.Design/methodology/approach -The sample size of this meta-analysis study consisted of 44 empirical papers obtained from nine databases and meeting the inclusion criteria.Findings -Systematic review results revealed that the use of VIKOR method has been increasing rapidly in the solution of supplier selection problems.Meta-regression analysis results suggested that the number of decision makers, number of alternatives, number of criteria, country and sector variables did not affect MS scores.Discussion -Using the fuzzy VIKOR method to solve the supplier selection problem were identified to provide a lower MS score, while using the integrated VIKOR method ensured a higher MS score.Detailed studies will provide a better understanding of the relationship between MS scores and the qualities of studies reporting these scores.
