MABAC framework for logarithmic bipolar fuzzy multiple attribute group decision-making for supplier selection

Abstract

In this article, we introduce logarithmic operations on bipolar fuzzy numbers (BFNs). We present some new operators based on these operations, namely, the logarithm bipolar fuzzy weighted averaging (L-BFWA) operator, logarithm bipolar fuzzy ordered weighted averaging (L-BFOWA) operator, and logarithm bipolar fuzzy weighted geometric (L-BFWG) operator, and logarithm bipolar fuzzy ordered weighted geometric (L-BFOWG) operator. Further, develop a multi-attribute group decision-making (MAGDM) methodology model based on logarithm bipolar fuzzy weighted averaging operator and logarithm bipolar fuzzy weighted geometric operators. To justify the proposed model’s efficiency, MABAC (the multiple attribute border approximation area comparison) methods are applied to construct MAGDM with BFNs established on proposed operators. To demonstrate the proposed approach’s materiality and efficiency, use the proposed method to solve supply chain management by considering numerical examples for supplier selection. The selection of suppliers is investigated by aggregation operators to verify the MABAC technique. The presented method is likened to some existing accumulation operators to study the feasibility and applicability of the proposed model. We concluded that the proposed model is accurate, effective, and reliable.

Bipolar Fuzzy Multi-Criteria Decision-Making Technique Based on Probability Aggregation Operators for Selection of Optimal Artificial Intelligence Framework

“…The outcome of MCDM is substantially influenced by the choice of a suitable AO, which also affects the robustness and dependability of the decision-making process. Because of the significance of the AOs in MCDM, various scholars diagnosed various AOs in the setting of BFS, such as Jana et al [44] devised Dombi, Wei et al [45] devised Hamacher, Riaz et al [46] diagnosed sine trigonometric, and Jana et al [47] interpreted logarithmic AOs within bipolar FS. There are various genuine-life dilemmas within BFS, where probabilistic information is required but all abovementioned AOs cannot consider the probabilistic information while aggregating the bipolar fuzzy information.…”

“…Jana et al [16] introduced innovative logarithmic operations for bipolar fuzzy numbers. They devised new operators based on these operations, namely, logarithmic bipolar fuzzy weighted averaging (L-BFWA), logarithmic bipolar fuzzy ordered weighted averaging (L-BFOWA), logarithmic bipolar fuzzy weighted geometric (L-BFWG), and logarithmic bipolar fuzzy ordered weighted geometric (L-BFOWG) operators.…”
