Abstract

In the resolution of group decision making problems where the consensus process can not be held face to faceby the experts it is usually difficult for them to be able to identify the closeness of the opinions of the rest of the experts, and thus, it is difficult to have a clear view of the current state of the consensus process. In this paper we present a tool that creates consensus diagrams that can help experts to easily comprehend the current consensus state and to easily identify the experts that have similar or very different opinions. Those diagrams are based on several new similarity and consistency measures.
