Rule 13 handles the case that some experts assign an integer that is less than 3 with non-confidence, while some confidently assign an
integer that is greater than 3 to express the same relationship with high confidence. In this case, it can be seen that
these experts have different opinions on determining the weighting; moreover, they show different confidence in making the decision.
Therefore, the larger weighting with higher confidence is adopted as the integrated weighting, and the confidence degree is set to “S”. Table
3 shows an illustrative example of this rule, where two experts (E1 and E4) have assigned weights that are less than 3 with non-confidence,
and three experts (E2, E3, and E5) have assigned values that are greater than 3 to represent the same relationship with high confidence;
therefore, the integrated weighting is equal to 5 by finding the maximum of values 5, 5 and 4, and the integrated confidence degree is “S”
(Sure). Another rule that is similar to this rule is given as follows:
