A Combined BWM-TOPSIS Approach Versus AHP-TOPSIS Approach: An Application to Solid Waste Management

Abstract

Multi-Criteria Decision Making (MCDM) is a tool used to evaluate and choose alternatives between multiple criteria when a decision is required. One trusted MCDM techniques is the Analytic Hierarchy Process (AHP). Recently, scholars have expressed a heightened interest in the Best-Worst-Method (BWM). In comparison to AHP, BWM is highly efficient in determining criteria weights. So, this paper illustrates how an approach combining BWM and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) improves the ranking of alternatives over an AHP-TOPSIS approach. The evaluation used seconder data from an earlier decision study to choose the suitable recycling collection method for recovered fiber. The BWM-TOPSIS approach provided precision advantages over the AHP-TOPSIS technique. The approach deserves increased use while undergoing further testing in future studies.
