The assessment level of experts in group decison making based on reciprocal judgment matrices

It is an important research topic to analyze the assessment level of experts in group decision analysis according to consistency analysis. In this paper, an analytic method is proposed to solve the problem for ranking and classifying the assessment level of experts based on preference information of reciprocal judgment matrices in group decision analysis. Firstly, the concept of reciprocal judgment matrix and its consistency is introduced. Then, the induced matrix and vector of every expert are constructed to calculate the deviation between the judgment matrix given by every expert and the complete consistency judgment matrix, and ranking and classification of assessment level of experts are obtained. Finally a numerical example is given to illustrate the use of the proposed analysis method.
