IASC2
The minimum extreme point of the centroid of an interval type-2 fuzzy set over with upper membership function and lower membership function can be computed using the following procedure:
The maximum extreme point of the centroid of an interval type-2 fuzzy set over with upper membership function and lower membership function can be computed by the following procedure:
Sort ) in ascending order and call the sorted by the same name, but now . Match the weights with their respective and renumber them so that their index corresponds to the renumbered .
