Comparison of Ranking Results and the Optimal Choice Obtained by Different Methods.

Method in Reference	Method Introduction	Ranking	The optimal choice
Zhang et al. (2015)	Developed a heterogeneous MCGDM method based on the degree of deviation, the alternatives’ relative closeness and the TOPSIS method.	A4 > A3 > A2 > A1	A4
Cheng et al. (2017)	A solution to the HMCGDM problem of HAD considering distance measurement under the triangular fuzzy sets decision-making environment is proposed.	A4 > A3 > A2 > A1	A4
Fei et al. (2021)	A heterogeneous MCGDM method that takes into account the different backgrounds and preferences of DM is proposed. The process is based on DST and incorporates belief entropy.	A4 > A3 > A1 > A2	A4
Our Method	We propose a novel IFSs based MCGDM method, which considers the reverse supply chain strategy of the CMW recycling alternatives.	A3 > A4 > A2 > A1	A3
