Study on Experts_ Judgment Level of Group Decision Making Based on Numerical Value Decision Matrix

It is an important research subject to carry on the classification to the level of judgment experts or experts´ judgments in the group decision and analysis. With respect to the problem of the level of experts´ judgment to the preference information of numerical decision matrix in the group decision making, an analytic method is proposed Firstly, the relevant characters of numerical decision matrix and group consistency are analyzed. Then, based on defining the educe matrix of numerical decision matrix are given by each expert, a taxis approach to judgment experts´ level are given. Meanwhile, based on defining the fuzzy relation matrix between the two experts, classified approaches to judgment experts´ level are given. Finally, a numerical example is given to illustrate the efficacy and rationality of arithmetic.
