An Efficient Model for the Approximation of Intuitionistic Fuzzy Sets in terms of Soft Relations with Applications in Decision Making

Algorithm 1

Procedural steps for better decision with the help of score function.

(1)	Compute the upper IF soft set approximation and lower IF soft set approximation of an IF set with respect to the aftersets;
(2)	Compute the score values for each of the entries of the and and denote them by and for all ;
(3)	Compute the aggregated score and ;
(4)	Compute ;
(5)	The best decision is ;
(6)	If has more than one value, say , then we calculate the accuracy values and for only those for which are equal;
(7)	Compute for ;
(8)	If , then we select ;
(9)	If , then select any one of and .
