Study on Divergence Based on the Grey Relational Degree in the Group Decision-Making
Expert is a very important factor that affects the outcome of decision-making. This paper applies the grey relational degree in measuring the similarity on the evaluation of decision-making scheme between individual expert and expert group, and establishes the research model of expert's decision-making divergence, which provides some theoretical basis for expert’s evaluative reliability and fairness, reveals some possible bias in attribute understanding as well as important deficiencies or loopholes that existed in schemes. Besides, it provides a better way of man-machine interface for hall for workingshop of metasynthetic (HWME) and a good chance for further discussion about minority’s different opinions. Finally, the approach is proved to be effective in revealing the divergence and deviation of decision making through the example.
