Abstract: The traditional case-based reasoning has some drawbacks, and it does not satisfy the demand of actual decision problem. This paper proposes a problem resolving method of conversation group case-based reasoning. It gives the resolving process and arithmetic in particularly and gives the structure of case base. A two level index based method is provided for the case index problem. The technique can overcome the limitation of traditional CBR, meet the requirement of decision problem. In the end, it gives a prospect to its application.
