Multi-criteria group decision-making method for green supplier selection based on distributed interval variables

Abstract

Addressing the multi-criteria group decision making problem with interval attribute values and attribute weights, this paper proposes a decision method based on attribute distribution information. The selection of green suppliers is taken as an example for decision analysis. First, in the case of group decision-making, the quantitative values of the evaluation attributes of green suppliers are imputed by decision-makers, and the relevant distributions are constructed for each attribute. Next, combined with the ranges of attribute values, the random interval values are used to describe the information represented by each attribute to overcome the loss caused by the aggregation of individual expert information into group information. We then propose the distributed interval weighted arithmetic average (DIWAA) operator and corresponding operation rules, which realizes the fusion of qualitative data and quantitative judgment. Thus, the proposed approach allows ensuring reasonable results of the multi-criteria analysis. We also construct a ranking method for alternatives based on distributed interval comprehensive scores. Finally, we verify the feasibility and effectiveness of the proposed method for the task of green supplier selection through numerical experiments.

A New Multi-Attribute Decision Making Method for Overvalued Star Ratings Adjustment and Its Application in New Energy Vehicle Selection

“…The evaluation value of each alternative under different attributes is given by each expert, which is denoted by various linguistic term sets. Common linguistic term sets include intuitionistic fuzzy sets [32], probabilistic linguistic term sets [33], interval values [34], linguistic distribution assessments [35], and so on. There are abundant decision making methods in the field of multi-attribute decision making, such as TOPSIS [36], TODIM [37], VIKOR [38], ELECTRE [39], MULTIMOORA [40], and so on.…”

“…Yang et al constructed an evaluation index system for the coordinated development of regional ecology based on ecological, economic, social, and policy factors; used the closeness to construct the value function to calculate attribute weights, and finally evaluated the regional ecological development performance of 27 cities in China based on the proposed heterogeneous decision model [46]. Huang et al used interval numbers to represent the attribute information in the group decision matrix, and then proposed a distributed interval weighted average operator to integrate qualitative data and quantitative judgments; then, they defined relevant operation rules, and finally ranked and selected the best green suppliers [34]. To solve the problem that different approximation methods for rough sets affect the results, Wang et al first proposed an attribute metric method based on fuzzy sets, and then constructed Choquet integral operators based on the attribute metric and matching degree, and finally used the operators to rank and select the alternatives [47].…”

Conceptual approach to valuation of climate change in EU countries through the prism of economic activities

“…Hwang and Yoon introduced the TOPSIS method in 1981. It is based on the concept that the best-chosen alternative has the shortest distance from the ideal positive solution and the longest distance from the negative ideal solution (Huang et al, 2021). The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a classical multi-attribute decision-making method widely used in various fields for decision-making or evaluation (Jureviciene et al, 2020;Liao et al, 2020;Skica et al, 2020;).…”

Sustainable/Robust Supplier Selection in the Post-Pandemic Era: Using Data Envelopment Analysis

“…The selection of sustainable suppliers embraces economic criteria, ethical business practices, and environmental and societal impact with the raised awareness of corporative social responsibility (Čiković et al, 2022b). Supplier evaluation includes an ecological commitment to reduce adverse environmental effects by integrating green supply chain management (Huang et al, 2022). The green concept is incorporated into the entire supply chain procedure from procurement, production, packaging, storage, and distribution (Shin & Cho, 2022).…”
