A novel hybrid MCDM approach based on DEMATEL, AHP and TOPSIS to evaluate green suppliers

Abstract

This study present a new hybrid strategic decision-making framework for multi-criteria assessment for Green Supply Chain supplier selection, which joins numerous green processes with order allocation for vibrant supply chains to deal with market differences. More precisely, the established approach replicates the knowledge attainment and manipulation in a way same to the decision makers who have congregated significant knowledge and expertise in procurement domain. DEMATEL is first applied to find the causal relationship between the criteria and to find out the most affecting criteria. AHP method is used for evaluation of green supplier criteria weights, which are qualitatively expressive. Thereafter, using TOPSIS method, the criteria application is quantitatively assessed for order allocation of suppliers. As a result, the approach produces decision-making knowledge, and thereafter, the established combination of rules for order allocation. To illustrate the applicability of the developed framework, a real-life study Indian electronics industry is developed, and the results are analysed accordingly.
