In the so called “Group Problem” (we would like to term it “Group-Consulting TypeCooperation”), ESs of the same cooperating group may have different views towards the same problem,and the differences may sometimes be very great. For the circumstance of those ESs with relativelycloser views, we present in this paper three methods of consistency treatment and a method for calcula-ting the maximal deviation of the confidence value about the cooperating group’s common view based onthe consistency degree of those different views. For the circumstance of those views being not very closeto each other and also not very different from each other, we designed two synthesis functions forsynthesizing multiple views. These two circumstances are formally defined in this paper. A comparison be-tween these two functions and the combining function in is also demonstrated. In the last section ofthis paper, we present a discussion about some further research topics of conflict-resolution in the groupproblem.
