For the circumstance of those ESs with relatively closer 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 on the consistency degree of those different views. For the circumstance of those views being not very close to each other and also not very different from each other, we designed two synthesis functions for synthesizing 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 of this paper, we present a discussion about some further research topics of conflict-resolution in the group problem.展开更多

文摘It is not objective to rate the decision-making factors in the traditional failure mode and effect analysis,so fuzzy semantic theory is used in this paper.Six fuzzy semantic scales and their corresponding semantics are summarized,and a defuzzification method is studied to obtain the fuzzy value table of the six fuzzy semantic scales.For the conflicts between experts in the traditional failure mode and effects analysis,a conflict-resolution algorithm is studied to obtain the failure risk order.Finally,a certain type of industrial valve is used as an example to prove the validity of the theory proposed in this paper.
