Study the supplier evaluation and selection in supply chain disruption risk based on regret theory and VIKOR method

PurposeIn the supply chain disruption risk, the issue of supplier evaluation and selection is solved by an extended VIKOR method based on regret theory.Design/methodology/approachConsidering the influence of irrational emotions of decision makers, an evaluation model is designed by the regret theory and VIKOR method, which makes the decision-making process closer to reality.FindingsThe paper has some innovations in the evaluation index system and evaluation model construction. The method has good stability under the risk of supply chain interruption.Originality/valueThe mixed evaluation information is used to describe the attributes, and the evaluation index system is constructed by the combined method of the social network analysis method and the literature research method to ensure the accuracy and accuracy of the extracted attributes. The issue of supplier evaluation and selection is solved by an extended VIKOR method based on regret theory.
