The Study and Application on a Method of Group Decision-Making on Case-Based Reasoning

This paper presents a method of group decision-making based on CBR. This method involves two steps. Firstly, decision-making problems are expressed by cases and the decision tree is created via ID3 algorithm. Then each decision-maker´s preference is incorporated via utility theory to attain group consistent preference; and on the basis of the group preference, the similar case is retrieved in the decision tree to get the solution. At the end of the paper, an example is given, which shows that the method is feasible.
