Rule 7 is used to handle the case that some experts assign “X” (no relationship) with high confidence while others confidently assign an
integer (having some degree of relationship) for the same relationship. In this case, it can be seen that these experts
have different opinions on determining the weighting; moreover, they show high confidence in making the decision. Therefore, the system
will return to ask the experts to check and reconsider their ratings. Table 3 shows an illustrative example of this rule; that is, two experts (E1
and E4) have assigned “X” with high confidence, and one expert (E3) has assigned an integer to represent the same relationship with high
confidence; that is, a conflicting opinion exists. In this case, the system will ask them to check and reconsider their ratings.
