Unlike inconsistency, disagreement is calculated based on the differences between the opinions or evaluations of the expert panel. If the disagreement among the expert panel is beyond a certain range (which is considered to be 10%), then a brief session should be conducted with the experts to try to convince that particular expert whose judgment was different from the rest. There are additional tests such as an F-test that can be performed to determine whether the disagreement among experts in a panel is statistically significant or not [6]. “Understanding and resolving the disagreement is an important aspect of the research and for building the decision model” [6].
