Visualization of the experts´ opinion consistency for group discussion

How to guide discussions in the group of experts from the divergent to convergent thinking is one of the hot issues of Hall for Workshop of Metasynthetic Engineering. This paper presents a method for consistency analysis and visualization of group´s opinions. The consistency of group can be measured through the Euclidean distance. The raw experts´ opinions are shown and analysed, and multidimensional scaling methods are used to visualize the group state to scattered-point graph. The group consistency analysis and visualization can be unified by drawing the group consistency on the graph directly. Finally, the visualizations of experts´ opinion and group state are implemented in the case of the simulation-based weapons acquisition to verify the validity of the method.
