Comparison of proposed IVIFE with other IVIF methods.

Method(s)	Alternatives					Preference order
	IVIFE (proposed)	4	1	5	2		3
IVIFV [52]	1	4	2	5	3
IVIFP [28]	4	1	5	2	3
IVIFE [34]	5	2	4	3	1

Note. In [52], the first three criteria are taken as cost and last three are taken as benefit. In [28], function is used, IVIF values are changed to IFV by taking the mean, value is taken as 0, and value is taken as (), where is the number of criteria. In [34], the linear order is achieved using TOPSIS method.
